                            Best Frames for Your Face Shape

What are the best glasses for your face shape? Some people say that their faces are not suitable for wearing glasses, it's not that you don't have a good face for glasses, but because you don't know what frames are suited for your face shape. Now let's begin. Choose your face shape.


An oval face has slightly wider cheekbones with a gently curved jawline.

Almost every kind of eyeglasses frame look perfect on oval faces, and the styles below are absolutely the best choice for you! They match your face structure so well!


A round face doesn’t have prominent cheekbones and forehead. It is less angular.

Large rectangle and square frames make your face look smaller and help balance your face ship.


Square face has more angular lines with equally wide cheekbones, forehead and jaw.

Round or oval frames can add softness to angular faces.


A heart face has a wider forehead and prominent cheekbones lined with a narrower chin.

We need styles that can visually narrow the forehead and widen the jaw. Aviator or cateye frames can perfectly add softness and balance to your face.


A diamond face is widest at the cheekbones and gradually narrows through to the forehead.

To soften a broader jawline, Polygon and Oversized frames are the best choices for you. They can draw attention to your brows and visually adjust your face shape.

                  How to Measure Your Pupillary Distance(PD)?

PD(or pupillary distance) is the distance between your pupils in millimeter. Your PD is very important for accurately fitting your lenses to achieve vision acurity. In general, this number will be provided on your prescription after the eye exam; if not, you can also get it measured at home. All you need is a friend or a mirror and a ruler.

                               Measure it with a friend’s help

Step 1: Stand with a friend facing you, look straight ahead, and place the ruler on the bridge of your nose.
Step 3: Close your right eye and open the left, then let your friend note the reading directly over your left pupil. That will be your PD.
Step 2: Close your left eye and let your friend align the 0 mm over the center of your right pupil

Step 4For measuring a PD with high accuracy, please do it 3 times and take an average number of them as the final PD measurement.

1. The average PD is between 54mm and 78mm.
2. For those requiring progressive lenses, we strongly recommend you get this information from your optician to ensure the accuracy of your glasses.
3. Your PD may be written in three ways: ▪ PD (OU), written as "64", means the Binocular PD which is for both eyes. ▪ PD (OD), means the Monocular PD for the right eye, PD (OS), means the Monocular PD for the left eye. A Monocular OD is written as two numbers, for example "32/30", "32" represents the PD for the right eye, and "30" for the left eye. ▪ Sometimes PD is written as "62/59" or they are labeled "Far" and "Near". Your PD is usually measured for distance vision, which is "Far PD", or "62" in this example. For reading glasses, doctors measure your "Near PD" or "59" in the example.

Always enter your "Far PD" for distance vision eyeglasses and enter your "Near PD" for your reading glasses only. For most people, the difference between Far PD and Near PD is about 2-3mm.

                               Glasses Lenses and Coatings

Glasses have become an indispensable item for our daily life. In addition to assisting your eyesight, a pair of well-chosen glasses can improve and even change your temperament. Many people who have normal vision also wear a pair of flat lenses. Do you know how to choose the right lens for you? Now let's learn a little bit about lenses and coatings.

Prescription Type

Single vision

The simplest form of glasses or contact lenses is the single-vision lens, made to correct the particular eyesight problem with a single prescription. If you have distance-corrective glasses, your prescription will begin with a (-) and your lens will be concave or curved inward, to correct your vision properly.


There are multiple focal points on the same lens.
If you have difficulty seeing at both close and long ranges, you may need bifocals or multifocal. These glasses correct your vision at multiple distances, allowing you to see clearly — both up close and from a distance.
Because these lenses are highly personalized, they can correct even the most unique eyes, and provide all the benefits of bifocal lenses without the obvious horizontal line.

Reading glasses

It is a kind of optical product, glasses for presbyopia, and belongs to a convex lens. These lenses are convex, or curved outward, and are appropriate for people with prescriptions beginning with a (+).
The reading glasses is to meet the need of the eye presbyopia crowd.

Lens Thickness

The refractive index of the lens, it's the ratio of the speed of light in a vacuum to the speed of light in the lens material, reflects the ability of a lens to refract light. The higher the refractive index of the lens the thinner the edge thickness of the lens. Currently, there are several mainstream lenses on the market, such as 1.57, 1.61, 1.67, 1.71, and 1.74.
1.57 Mid-Index -Standard Lens This index is most suitable for prescriptions with an SPH correction of +/-2.25 and below, or a CYL correction of +/-1.50 and below. 1.61 High-Index-Thin and Light Lens These lenses are thinner and stronger than their 1.5-index counterparts, handling SPH corrections between +/-5.00 and +/-4.00, and CYL corrections of +/-3.00 and below. 1.67 High-Index-Ultra-Thin Lens People with SPH corrections between +/-4.25 and +/-6.75, and CYL corrections between +/-2.25 and +/-3.00. 1.71 High-Index-Super-Thin Lens We typically recommend these lenses for people with SPH corrections between +/-7.00 and +/-9.00, and CYL corrections between +/-3.25 and +/-4.00. 1.74 High-Index-As Thin as Possible Lens These lenses are best for prescriptions with SPH corrections of +/-9.25 and above, and CYL corrections between +/-4.25 and +/-6.00.

For stronger prescriptions, choose a higher index for a thinner and lighter lens.

UV blue blockers aurovila

UV blue blockers

Blocks high-energy visible (HEV) blue light and provides maximum UV protection, suitable for use when Apply to daily wear. If you have difficulty seeing at both close and long ranges, you may need bifocals or multifocal. These glasses correct your vision at multiple distances, allowing you to see clearly — both up close and from a distance. Apply to daily wear watching a computer or TV or mobile phone.

Photochromic aurovila


Photochromic lenses are optical lenses that darken on exposure to specific types of light of sufficient intensity, most commonly ultraviolet (UV) radiation. In the absence of activating light, the lenses return to their clear state. It can be used indoors as ordinary optical glasses and outdoors as sunglasses. 

Polarized Sunglass Lenses aurovila

Polarized Sunglass Lenses

It provides superior glare protection — especially on the water. Polarized lenses contain a special filter that blocks this type of intense reflected light, reducing glare.
These glare-reducing lenses are great for driving, as well as water and snow activities.


Plastic lenses are nice and light but do tend to scratch quite easily.
Glasses lenses can be provided with anti-reflection coatings which virtually eliminate distracting reflections off the lens surfaces. Reducing reflected light is particularly helpful for computer users and night driving.
Anti-reflection coatings also improve the cosmetic appearance of your glasses and can make thick lenses look thinner. The coating is also roughly divided into three: standard
anti-reflection coating, superhydrophobic anti-reflection coating, aoleophobic anti-reflection coating.

lenses coating aurovila

Standard anti-reflection coating

Anti-reflective coating (also called "AR coating" or "anti-glare coating") improves vision, reduces eye strain, and makes your eyeglasses look more attractive. Anti-reflective lenses are important for nearly everyone in the modern world — especially those working around computers or cameras or regularly driving at night.

Super-hydrophobic anti-reflection coating

With a coating of no less than 16 LAYERS, these lenses are immune from attack by dirt and wear and tear. If you live in a rainy area, work, or live around water sources, or simply like to be in and around the water, we recommend looking into this lens coating to help keep your lenses as clear as possible!

Oleophobic anti-reflection coating

With a coating of oleophobic, these lenses are immune from attack by fingerprints and greasy dirt. Almost everyone needs an oleophobic anti-reflection coating, our fingers and skin can't avoid contact with the glasses, so this coating is important for everyone.

                         Bifocal Lenses VS Progressive Lenses

Bifocal literally means “two focuses”, which contains two different prescriptions: an upper section to allow for distance vision and an additional power on the bottom part of the lens to aid in close-up focus. The result is vision clarity between distance and near with one pair of glasses.
However, the intermediate distance of bifocal glasses has poor visual effects. Produce an “image jump” phenomenon and have a poor appearance. Due to its significant shortcomings and the popularity of progressive lenses, bifocal lenses have been basically eliminated.
Progressive lenses are developed on the basis of bifocal lenses. In addition to not having to remove the glasses, the wearer can also move the line of sight gradually between the upper and lower focal lengths when observing far/near objects. The eyeball needn’t constantly adjust the focal length, and there is no obvious dividing line between the two focal lengths.

AUROVILA Bifocal Lenses VS Progressive Lenses

For the crowd

Progressive lenses are suitable for the following crowd:
▪ Myopia control lenses for teenagers -- used to alleviate visual fatigue and control the development speed of myopia.
▪ Anti-fatigue lenses for adults -- for teachers, doctors, and people who use too much proximity and computers to reduce visual fatigue at work. And it eliminates bothersome "image jump" caused by bifocals.
▪ Progressive lenses for middle-aged and elderly -- a pair of glasses which is easy to see near and far. In addition, they have the same beautiful appearance as single lenses.

How to get used to progressive lenses

▪ Look far, then focus on something closer as you lower your eyes to the mid part of the lenses.
▪ Then, take a book and look through the bottom of the lenses.
▪ Next try moving your head and not just your eyes up and down and side-to-side as you look through the different fields of vision.
▪ Remember to use your head to point towards where you wish to look.
▪ Please note that if you look through the corners of the lenses, they will always seem a bit blurry. That’s completely normal!

AUROVILA Progressive Lenses

Notices for wearing

1. When choosing the frame, you'd better choose a large frame. Because the lens is divided into far, middle and near zones, only large frames can ensure a wide enough zone for the near part. Since the learger the lens is, the thicker the edge of lenses will be, it is best to choose a full frame, which can cover the thickness of the edge of the lens.
2.Generally, it takes about a week to adapt, but the length of the adaptation period varies from person to person. When you feel dizzy, you should walk slowly. Since both sides of the lens are astigmatic disorder areas, it is not clear to see objects on both sides through the light of the eyeball, and it is necessary to turn the neck and the eyeball to see objects at the same time.
3. When going downstairs, the glasses should be lower and you should try to see from the distance zone.

                                 Blue Light Blocking Lenses

Compair with regular lensesBlue Light Glasses Reglazing Online | Reglaze Specs
Various types of led light-emitting display devices, such as TVs, computers, and mobile phones, etc, have made the image quality more bright and beautiful, which tends to increase the blue light intensity of led backlights. With the popularity of these electronic products and penetration into all aspects of life, the chance of each person's exposure to blue light has increased dramatically. For ordinary people, blocking long-time exposure to blue light is the most effective way to reduce damage, and the use of anti-blue light glasses can effectively solve this problem.The anti-blue light lens is a lens that prevents blue light from irritating the eyes. The special anti-blue lens can effectively isolate ultraviolet light and radiation and can filter blue light, which is suitable for people who often watch TV, computer or mobile phone.
Bad sleep can be linked to this devastating health issue
Hazards of Blue Light

Damage to Eyes

Harmful blue light has extremely high energy and can penetrate the lens to the retina, causing the atrophy and even death of retinal pigment epithelial cells. The death of light-sensitive cells will result in decreased or even complete loss of vision, which is irreversible. Blue light can also cause maculopathy.

Visual Fatigue:

Because of the shorter wavelength of blue light, the focus is not on the center of the retina, but farther forward. To see clearly, the eyeball is in tension for a long time, causing eye strain. Long-term visual fatigue may cause symptoms such as deepening myopia, double vision, easy serialization when reading and inability to concentrate, affecting people's learning and working efficiency.

Poor Sleep Quality:

Blue light inhibits the production of melatonin, which is an important hormone that affects sleep and regulates jet lag. This is why playing with your phone or tablet before bed can lead to poor sleep or even difficulty falling asleep

                                      How to wear your glasses?

1. Wear glasses with both hands

Slide the arms over your ears and lower the frame gently onto your nose.

Always handle your glasses with two hands to reduce strain on the hinges.

Place the frame lightly on your nose. Too much pressure can cause a lasting indentation to form on the bridge of your nose.

2. Wear your glasses on the top of your nose

When you have your glasses on, touch the nose bridge with your forefinger and push it up so that the frames sit comfortably on the top of your nose.

Unless your optician has specifically instructed you to wear your glasses in another position, your glasses should sit comfortably between your eyes at the apex of your forehead.

Don't stretch them out. Make sure that you don’t rest your glasses on top of your head as it can stretch them out of shape.

3. Don't make them too loose or tight

The distance between the arms of the glasses should be appropriate, keep the arms of your glasses properly bent.

Generally speaking, the distance between the lens and the eye should be twelve millimeters, which is not too far away from the standard. If not, because of the prism effect will

The prismatic effect can cause dizziness, distorted vision, fatigue, etc.

4. Keep the lenses clean

Wipe the lenses with a special eyeglass cloth and clean your glasses regularly with mild soap and water.

Please keep the lens clean, otherwise, it will affect your vision and may deepen your prescription.

5. When not wearing, the glasses should be put into the glasses box

Glasses should also be protected when not in use, by wrapping the lenses in flannel and closing the left and right lens legs in turn. Then place the glasses in the case to protect them from external impacts.

In daily use, remember to fold your glasses when you remove them and place the lenses facing up.

                           How to Clean Your Eyeglasses?

Cleaning your eyeglasses daily is the best way to keep them looking great and avoid scratched lenses. But there’s a right way — and plenty of wrong ways — when it comes to how to clean glasses.

Follow these tips to clean your eyeglass lenses and frames to keep your glasses in top condition. These cleaning tips will also help you keep your sunglasses, safety glasses and sports eyewear in great shape.
1. Wash and dry your hands
Before cleaning your eyeglasses, wash your hands thoroughly. Use lotion-free soap or dishwashing liquid and a clean, lint-free towel.

2. Rinse your glasses under a gentle stream of tap water
This will remove dust and other debris, which can help avoid scratching your lenses when you’re cleaning them. Avoid hot water, which can damage some eyeglass lens coatings.

3. Apply a small drop of lotion-free dishwashing liquid to each lens
Most dishwashing liquids are very concentrated, so use only a tiny amount. Or apply a drop or two to your fingertips before touching the lenses. Use only lotion-free brands.

4. Gently rub both sides of the lenses and all parts of the frame
Make sure you clean every part of your glasses, including the nose pads and the temples of the frame. Also, clean the area where the edge of the lenses meet the frame — dust, debris and skin oils frequently accumulate here.

5. Rinse both sides of the lenses and the frame.
Failing to remove all traces of soap will cause the lenses to be smeared when you dry them.

6. Gently shake your glasses to get rid of most of the water on the lenses
lnspect the lenses carefully to make sure they are clean.

7. Carefully dry the lenses and frame with a clean
lint-free towel. Use a dish towel that has not been laundered with a fabric softener or dryer sheet (these substances can smear the lenses). A lint-free microfiber cloth is also a good choice. Make sure the cloth is perfectly clean. Dirt or debris trapped in the fibers of a towel can scratch your lenses. Also, any cooking oil, skin oil or lotion on the towel will smear your glasses.

8. Inspect the lenses again
If any streaks or smudges remain, remove them with a clean microfiber cloth — these lint-free cloths are available at most optical shops or photography stores.

                                   Cleaning glasses: Don’ts

DON’T use your shirttail, blouse or other clothing to clean your glasses, especially when the lenses are dry. This can scratch your lenses.

DON’T use saliva to wet your lenses. DON’T use household glass or surface cleaners to clean your eyeglasses. These products have ingredients that can damage eyeglass lenses and coatings.

DON’T use paper towels, napkins, tissues or toilet paper to clean your lenses. These can scratch or smear your lenses or leave them full of lint.

DON’T try to “buff away” a scratch in your lenses. This only makes the situation worse.

Eyeglass cleaners and cleaning cloths

Spray eyeglass lens cleaners are available where you purchase your glasses and at your local drug or discount store. These can be helpful if you are traveling or don’t have dishwashing soap and clean tap water available.

If tap water isn’t available, use plenty of the spray eyeglass cleaner to flush away dust and other debris from your lenses before wiping them dry.

If your lenses have anti-reflective (AR) coating, make sure the eyeglass cleaner you choose is approved for use on anti-reflective lenses.

When using disposable lens cleaning wipes, first inspect the lenses for dust or debris. To avoid scratches, blow any debris off the lenses before wiping them.

Microfiber cleaning cloths are ideal for cleaning glasses. These cloths dry the lenses very effectively and trap oils to avoid smearing.

But because they trap debris so effectively, make sure you clean the cloths frequently. Hand-wash the cloth using lotion-free dishwashing liquid and clean water; allow the cloth to air dry.

How to remove scratches from glasses

Unfortunately, there is no magic cure for scratched lenses. Once your glasses are scratched, they are scratched.

Some products are designed to make the scratches look a little less visible. Most of these products are just waxy substances that wear off easily. Results with these products are mixed, depending on the location and depth of the scratches. Also, they often will smear anti-reflective lenses.

Besides reflecting light and interfering with vision, scratches can affect the impact resistance of your eyeglass lenses. For optimum vision and safety, replace your lenses if they become scratched.

When purchasing lenses, choose those that have a durable scratch-resistant coating. And ask your optician if your purchase includes an anti-scratch warranty — especially if scratched lenses have been an issue in the past.

Professional eyeglass cleaning

If your lenses are in good shape but the nose pads or other parts of the frame have become impossible to keep clean, return to where you purchased your glasses.

An eye care professional may be able to deep-clean your glasses with an ultrasonic cleaning device. They also can replace yellowing nose pads with clear new ones.

Store your glasses in a case

Eyeglass lenses can easily get scratched if you fail to store them somewhere safe. This includes when you take them off at bedtime.

Always store your eyeglasses in a clean storage case, and NEVER place them on a table or counter with the lenses facing down.

If you don’t have a glasses case handy, place your glasses upside down with the temples open — somewhere safe, where they won’t get knocked off a table or countertop.

Glasses don’t last forever

All eyeglass lenses will eventually get a few scratches. Eyeglasses lenses are scratch resistant, not scratch-proof.

When purchasing glasses, ask about anti-scratch warranties for your lenses. This is especially important for children’s eyeglasses or if you wear glasses in dusty conditions.

Following the above tips is the best way to keep your glasses clean and scratch-free for as long as possible.

If your lenses are badly scratched and your eyeglass prescription has expired — or you simply want new glasses — schedule an eye exam with an eye doctor near you.

                          How To Measure Your Frame Size

Choosing the right size is the key to ensuring you're getting the right fit. If you want to find a suitable size, you can check the size of your current frame, or measure your current frame yourself.

                              How To Adjust Your Eyeglasses?

Whether you just get your new glasses or have worn them for a long time, the frames may pinch your nose, slide out of place or simply appear crooked. Except for taking them to an optometrist for an adjustment, you can do it yourself by following these instructions.

Stand in front of a mirror and look straight ahead, make sure that the middle of the lenses is level with the center of your eyes. Check for the fit and make some adjustments properly.

Remember to make small adjustments and be extra careful each time.

1. Your glasses are sitting too low on your nose

Use your thumbs to gently push the nose pads closer both sides until they fit comfortably.
Run the earpieces under warm water (not boiling) for 30-60 seconds. Gently bend the earpieces slightly downwards to add curve.

2. Your glasses are sitting too high on your nose


Use your thumbs to gently push out on the nose pads both sides until they sit snugly on your nose.


Run the earpieces under warm water (not boiling) for 30-60 seconds. Gently bend the earpieces upwards to relax the curve.

2. Your glasses are sitting too high on your nose


Gently bend the arms or earpieces with small pliers or your bare hands.

Carefully heat the higher arm with a hair dryer to make the plastic pliable. Slowly move the plastic downward with your hands until it is in the desired position.
