Buying Sunglasses Guide (Blog)

What to Look for When Buying A Pair of Sunglasses?

Sunglasses give us essential UV protection when we are outside, which makes life easier and more comfortable. If you spend the entire day outside on a bright, sunny day without applying sunscreen, you risk damaging the surface of your eyes and experiencing eye problems. Standards for labeling and UV protection are optional; they are not necessary.

Therefore, getting a pair of fashionable sunglasses to protect your eyes cannot be easy if you don't know what to look for or grasp the optical jargon for the lenses. But with proper guidance, you can make well-informed choices.

Sunglasses are an essential piece of eyewear. In addition to completing your appearance, it shields you from the sun’s harmful rays. Whether you are purchasing designer or prescription sunglasses online, a few considerations could make or break your choice. Have a look at some of the factors to think of while buying sunglasses below:

Opt. for Larger Sunglasses

Who said that size is unimportant? Insufficient UV protection from your sunglasses can make sunlight more easily harm your eyes. Therefore, while buying sunglasses online, be careful to check the sizes. Choose large or wraparound eyewear. It will reduce the number of UV rays that reach the eyes, making it safe to wear sunglasses. Because you'll be wearing your larger sunglasses for extended periods of time in the sun, keep fit and comfort in mind while selecting them.

Check the Color of the Lens

There are many different shades of lenses for sunglasses, including grey, green, and brown. Although the color of the lens can influence the amount of contrast observed, sunlight absorption is unaffected. Certain lens colors might increase contrast for athletes who play sports like baseball or golf.

Investigate UV Protection

Without question, the first component is one of the most crucial. Don't let the price or color intimidate you. The lens's degree of darkness, color, or price has no bearing on how well it blocks UV radiation. Specific chemicals can be added to the lens material to boost UV immersion when making lenses.

Alternatively, specific lens coatings can be used after both glass, and plastic lenses have absorbed UV rays. Wear UV-ray-blocking sunglasses at all times. Some labels may have stated UV absorption up to 400nm, which is the same as 100% UV absorption.

Check to See if They Can Sufficiently Obscure Light

Make sure the sunglasses you wish to buy have excellent light-blocking abilities in addition to UV 400 protection. The ability to make any pair of sunglasses light-blocking is available.

They should therefore block between 75% and 90% of visible light. When wearing sunglasses in front of a mirror, if you can clearly see your eyes through them, they are not dark enough to hide sunlight.


Polarized lenses provide a number of advantages. Therefore they should, at the very least, be taken into account when purchasing sunglasses. Polarized lenses work by blocking light rays from entering your eyes after they have been reflected off of surfaces.

Since the light that enters your eye through a polarized lens has already been filtered, the wearer sees a different way of seeing that reduces glare, produces less eye strain, and generally delivers better vision.

Polarized lens technology can lessen glare's effects, improving eye comfort and driving safety by obscuring reflections. This problem can be resolved while simultaneously improving eye comfort and relaxation.

Not to mention, polarized lenses may present colors and visuals in previously unimaginable ways. Learn to perceive the smallest details with accuracy and cleanliness that routinely astounds you.

Measure the Caliber of the Lens

It's important to take the hue and lens quality into account. Instead of a darker tone, seek out a consistent tone. You can walk straight while looking through the distance of the lenses to check for flaws like the edge of a door by holding the glasses out at arm's length. The glass should then be placed over the line with care. If the straight edge curved, bent, swung or behaved in any other manner, the lens would not be flawless.

Comfort and Suitability

Before selecting the finest eyeglass fit, there are numerous factors to consider. The distance between the arms of the frame, the length of the bridge on the nosepiece, and the thickness of the lens. Your appearance and vision may be made or broken by the fit.

The finest sunglasses for filtering stray UV rays while commuting wrap around the eyes and fit tightly. Additionally, they keep out allergens and dust. You have found the ideal fit if the sunglasses are cozy to wear and shield your eyes from the sun.


Choosing secure sunglasses is a difficult option. We know that protective eyewear comes in a wide range of sizes and materials. At this stage, things might become very perplexing.

But there is one specific factor to take into account when purchasing sunglasses: your way of living. Consider your regular daily activities and hobbies. Surprisingly, using this technique can give you the qualities you want.

Face Shape

Remember when we talked about the sizes of sunglasses? Truly blind purchasing is an impossibility. Before buying sunglasses, it is important to consider the form of your face. It demands all of your attention.

Have you got an oval or an oblong face? Your sunglasses, regardless of style, should balance and highlight the features of your face. You can’t recklessly go huge with your sunglasses without properly examining your face.

Choose Quality Over Pricey Options

Optometrists and ophthalmologists advise wearing hats and sunglasses when going outside on a sunny day, especially if you reside in a nation close to the equator or at a high elevation. That eye safety doesn't have to be pricey is what's exciting.

Costly items are not always of the highest caliber or offer the best eye protection. Therefore, it’s not always true that pricey sunglasses will give your eyes enough light protection. Cheaper sunglasses can occasionally be more practical than more costly ones.


A lens that is really shatterproof does not exist. Every pair of sunglasses must adhere to fundamental FDA requirements for impact resistance. When hit, glass lenses are more prone to break than plastic ones.

However, polycarbonate lenses, which are more impact-resistant than conventional plastic ones, are typically used in sports sunglasses. Look for scratch-resistant polycarbonate lenses if you decide to buy eyeglasses.

Steps to Check the Lens’ Quality

You may make sure that the lenses of non-prescription sunglasses are made correctly by carrying out the following procedures:

1. Look at anything with a rectangular pattern, such as a floor with tiles.

2. Cover one eye while keeping your glasses at a comfortable distance from your face.

3. Move the glasses carefully up, down, and side to side while looking through the lenses.

4. If the rectangular lines stay parallel, the lenses will be right. If the lines move or waver, particularly in the middle of the lens, try a new pair.


Sunglasses are crucial for eye protection since they reduce glare in any season or location where exposure to the sun's rays and their reflection could harm your eyes and vision. The considerations mentioned above should be examined before choosing a pair of sunglasses.
