Best Sunglasses of 2021 [Buying Guide]

Best Sunglasses to buy

If you’re extremely light-sensitive, you ‘re likely to see sunglasses as an accessory to your outfit or a luxury you can do without if you lose them when you leave your house.

The reality is that sunglasses are an essential piece of safety equipment that everybody can wear.

Recent reports have shown that the prevalence of cataracts, glaucoma, macular degeneration, and other eye disorders is increasing and the average age of those affected is dropping.

Optometrists suggest that everybody wears shades, even on gloomy days, because much like our bodies, our eyes will get sunburned, and it can lead to long-term harm and a greater risk of eye issues as we’re older.

Besides the average person knocking around town on a sunny day, sunglasses are essential for drivers, hunters, hikers, military personnel, and law enforcement.

To these men and women, eyewear is a vital protective device that covers their eyes in ways that go well beyond possible sun exposure.

Why do we wear sunglasses?

Why do we wear sunglasses?

Sunglasses, often lovingly referred to as sunglasses, have long been the world’s favorite item of defensive eyewear helping to obstruct dazzling sunshine.

Substantially minimizing the harm and distress done to your eyes when exposed to high-energy artificial light, sunglasses become your best friend during long summers.

In some situations, sunglasses often act as visual aids to help fix or support people with vision disabilities.

Visual clarity:

Besides convenience, sunglasses have also been known to increase visual visibility due to their defensive role. When you are a patient who has been given mydriatic eye drops, sunglasses of different kinds may be used to make eye exams smoother.

Sunglasses should also be used to see better through the sun, removing the haze that is transmitted at certain angles from the surface of the water.

sunglasses Fashion trends

Universally, sunglasses were perceived to be a very hip style reference. Each year, different varieties of designer sunglasses make their way into the front line of fashion trends, posing as essential accessories to complete the summer look.

Sunglasses are typically seen to add a ‘coolness’ factor to the wearer, depending on the particular shapes in vogue.

Hiding emotions:

Hiding emotions

Feeling anti-social? Step out with a pair of mirror shades so that you can easily prevent eye contact with someone you’re not referring to. Sunglasses can be used to conceal your feelings for both personal and technical purposes, such as poker.

Concealing Abnormalities:

Conceal your Abnormalities

Severe vision disability can make the eyes look in the opposite direction all the time, so this awkward condition can be stopped by offering a pair of sunglasses.

Alternatively, those with bloodshot eyes, exophthalmos, cataract, nystagmus, dilated or contracted pupils, or even just a black eye due to physical abuse may use sunglasses to hide their eyes.

Eyes protection:

Eyes protection with sunglasses

Extended sensitivity to both visible and unseen light elements is particularly detrimental to the skin, and this is where sunglasses come in handy. Sunglasses shield you from UV radiation, which is believed to cause a variety of disorders.

Types of Sunglasses

Different Types of Sunglasses

Many sunglasses are designed to shield our eyes from the adverse effects of the sun. Sometimes the sunglasses labels offer protection against UV light and other forms of natural radiation.

It is important to learn what kind of light you need to shield your eyes from, and what kind of light is not inherently harmful.

Ground and polished

Ground and polished

Any non-prescription glasses are ground and polished to enhance the appearance of the lenses. Non-prescription lenses that are not ground and polished do not damage the eyes

You want to make sure that the lenses you buy are made properly. To judge the quality of non-prescription sunglasses, look at something with a rectangular pattern, such as a floor tile. Place your glasses at a safe angle and cover one eye.

Slowly push the lenses from side to side, then up and down. If the lines are straight, the lenses are fine. If the lines are wiggling, especially in the center of the lens, try another pair.


Polarized lenses

Polarized lenses remove transparent glare — sunlight that reflects off shiny surfaces such as concrete, car windows, chromed walls, or snow. They may be particularly useful for driving and fishing.

Polarization has little to do with the absorption of UV rays, but often polarized lenses are often paired with a UV-blocking agent. Check the mark to ensure that the lenses have full UV protection.


photochromic lenses

The photochromic lenses naturally darken in bright light and become brighter in low light. The rest of the darkening takes place in about half a minute, while the lightning takes approximately five minutes. Photochromic lenses are available in a uniform or gradient tint.

While photochromic lenses can be good UV-absorbent sunglasses (again, this advantage must be mentioned on the label), it takes time for them to adapt to specific light conditions.

Gradient lenses

Gradient lenses

Gradient lenses are continuously shaded from the top to the bottom or from the top and bottom to the center. Single gradient lenses (dark at the top and lighter at the bottom) can cut the glare from the sky but allow you to see below.

They’re good for driving because they don’t block the view of the windshield. However, they are not as good at reducing the light in the icy surroundings or at the beach.

Double-gradient lenses (dark on top and bottom and lighter in the middle) may be ideal for activities where light is filtered out of the water or snow, such as sailing or skiing.

Double-gradient lenses are not approved for driving because they make the windshield look dark.

Blocks 90% of infrared rays

Blocks 90 percent of infrared rays

Infrared wavelengths are invisible, producing heat. Sunlight has low levels of infrared rays, and infrared is well tolerated by the eye.

Many manufacturers of sunglasses make safety promises for their products dependent on infrared protection, but testing has not shown a near correlation between eye disease and infrared radiation.

Mirror coated

Mirror coated

Mirror surfaces are thin films of various colored lens coatings. Although they do minimize the amount of visible light reaching your body, do not believe that they can completely shield you from UV radiation.


blue light blocking glasses

This is also unclear whether the blue light is detrimental to the retina. The lenses that block all the blue light are usually amber and make your surroundings look yellow or orange.

The tint is said to make distant objects appear more distinct, especially in snow or haze. Of this cause, amber sunglasses are popular with skiers, hunters, boaters, and pilots.

Wraparound style

Wraparound style sunglasses

Wraparound lenses are designed to prevent the sun from reflecting through the frames and in the eyes.

Research has found that enough UV rays are placed into ordinary eyeglass frames to reduce the advantages of safety lenses. Large-framed sunglasses can shield the eyes at all angles.

Lens darkness

Lens darkness sunglasses

A medium lens is perfect for day-to-day use, but if you use glasses in very bright conditions, use a darker lens.

The color and the degree of darkness do not tell you much about the capacity of the lenses to suppress UV radiation.


Impact-resistant sunglasses

All sunglasses must meet with the health effect requirements set by the Federal Food and Drug Administration (FDA). Neither lens is completely unbreakable, but plastic lenses are less likely to crack when struck by a projectile or a stone than glass lenses.

Many non-prescription sunglass lenses are made of rubber. Polycarbonate plastic sunglasses, used in many sports, are especially sturdy, but easily scratched. When you buy polycarbonate lenses, look for lenses with scratch-resistant coatings.

Blocks 99 percent of ultraviolet rays

ultraviolet rays

With this option, you can also buy sunglasses. Long-term exposure to ultraviolet ( UV ) radiation in sunlight is associated with cataracts and eye growth, including cancer.

UVB radiation is known to be more damaging to the eyes and skin than UVA radiation.

Both plastic and glass lenses absorb some UV light, but UV absorption can be improved by adding chemicals to the lens material during production or by applying special lens coatings.

Search for shades that block 99 percent to 100 percent of all UV rays. Any manufacturers’ labels say “UV absorption up to 400 nm.” This is the same thing as 100% UV absorption.

Radiation Protection

Radiation is one of the key threats of our eyesight and is perhaps the least known. Even the worst infomercials or cheapest convenience store sunglasses are “100 percent UVA and UVB security,” so what does that mean? The dictionary definition of radiation is as follows:

  • The mechanism by which energy is released as particles or waves.
  • The full cycle in which energy is released by one body transferred through an intermediary medium or vacuum and absorbed by another body.

The main part of this term, as far as the eyes are concerned, is the last four words: “absorbed by another object.” As the sun releases radiation, exposed eyes absorb it and harm will occur.

Our eyes are especially vulnerable to sunlight, and the cells in the eye are not recycled nearly as easily as our skin cells are, and damage from solar radiation has long-lasting consequences.

Much like we (should) put sunblocks on when we’re outside to prevent sunburn, we (should) cover our eyes when we’re outside, for the same reason.

If we can’t slather lotion on our eyeballs, the next best thing to do is wear sunglasses to contain the most dangerous radiation — ultraviolet. Let’s have a look at the various forms of UV radiation that can do harm to our skin.

As the name suggests, ultraviolet (UV) radiation experiences wavelengths higher than violet light, with the lowest wavelength visible to humans. UV radiation is divided into three types: A, B , and C.

UVA Rays:

UVA rays account for 95% of Ultraviolet radiation entering the Earth’s surface. UVA rays do not differ in intensity across the year, and while much less intense, they are 30-50 times more abundant than UVB rays.

Recent findings have also demonstrated that UVA rays are capable of leading to the growth of skin cancer and photoaging, and have been related to the development of some forms of cataracts.

UVB Rays:

Such rays are very strong and are the main cause of sunburn and cancer, which can be very harmful to the body.

UVB rays range in strength during the year and are much higher in the summer months between 10 a.m. and 4 p.m. – this is the time of year when the Earth’s axial inclination is tilted towards the sun, allowing UVB rays more oriented.

While UVB rays are most powerful in the summer, they have the potential to burn or affect the skin and eyes all year round, and their effect is intensified by snow.

UVC Rays:

The good news is that while this is the most effective and thus theoretically most harmful of the UV spectrum, nearly all of it is absorbed by the ozone layer.

The bad news is that the ozone layer is thinning, and there is an growing possibility that UVC will inevitably infiltrate to the atmosphere, followed by a host of severe health threats.

The U.S. Environmental Protection Agency ( EPA) has an impressive sun protection feature on its website, and does a fine job in describing the UV Index. Except at the lowest ranking of 0, the EPA still advises that sun glasses be used.

Frame Sizes

sunglass frame size guide

Eye-glasses come in a variety of sizes. Several sizes fit one person, but it is important to be as accurate as possible to ensure a good fit.

Eyeglasses are sized in three sizes, each representing a different section of the lens.

Lens Size:

The size of the lens measures the horizontal width of each lens, ranging from 40 mm to 62 mm. The size of the lens represents only the real size of the lens, without some portion of the frame.

Bridge size:

The height of the bridge calculates the distance (connected to the bridge) between the two lenses. The height of the bridge can change based on the form of the particular profile.

Temple length:

The length of the temple determines the scale of the temple from the hinge that links the lens to the end of the rim.

use the chart below to convert your measurement to a frame size that may suit your face.

Suggested Frame SizeFace Size (temple to temple)
49MM115MM or 4.5″
52MM127MM or 5″
54MM130MM or 5.125″
55MM135MM or 5.25″
57MM140MM or 5.5″
58MM146MM or 5.75″
61MM152MM or 6″

Frame Material

Choosing a frame material that suits your intent is important as it plays a major role in the comfort, protection and versatility of your new glasses.

Various materials adapt themselves to diverse purposes, price levels and types. There are distinct advantages and drawbacks to each material.

Metal Frame

Metal is one of the materials that is widely used in the production of sunglasses frames. Its malleability, corrosion resistance and ease of modification make it very easy to conform to multiple face shapes and frame types.

Metal frames tend to be more costly, less durable and not suitable for action sports.

Nylon Frame

Nylon frames should be the starting point for sports and performance workouts. Nylon frames are immune to temperature fluctuations and remain super-flexible while preserving the stiffness needed for protection.

Companies use various brand names for their frame nylons, including Grilamid (not company-specific) and O-Matter (specific to Oakley). Nylon frames prove to be smaller, lighter and heavier than conventional metal frames.

Plastic Frame

Sunglasses can be made from a wide range of plastic frames, from acrylic to polyurethane. Plastic frames are usually the cheapest frames available and can be a nice choice if there is a price problem.

Aluminum Frame

Aluminum frames are designed to be lightweight and extremely corrosion resistant. Its common use is for high-end eyewear manufacturers because of its distinctive appearance.

Pure aluminium is actually very soft and weak; however, consumer aluminium with minimal quantities of silicon and iron is hard and solid, making it a sturdy pair of eyewear.

Polycarbonate Frame

This flexible, durable plastic gives serious impact resistance and can be used in many sports and safety glasses.

They tend to be stiff frames, considering their toughness, and are not very flexible. Polycarbonate frames make a good alternative for children as frames can be battered.

Titanium Frame

Generally used in high-end sunglasses, Titanium frames are durable (duhh), scratch-resistant, and appear to be on the higher side of things.

Acetate Frame

Acetate is a plastic, so it’s a little different. Acetate frames are heavier, more durable and inherently lighter than regular plastic frames (usually Acrylic or Polyurethane).

Acetate frames can come with a wide range of colors and materials, and since the color is embedded in the object itself instead of being sprayed over the color appears to last.

Lens Materials

Acrylic Lenses

Acrylic lenses are the perfect option for low-cost sunglasses and the preferred alternative for casual or fashion sunglasses. They maintain much of the reliability and visual consistency of the top-shelf options with slight sacrifices but without a heavy price tag.

Polycarbonate Lenses

Polycarbonate acrylic lenses are the perfect bet for individuals who are going to be movin’ and shakin’ in their sunglasses. Polycarbonate lenses are made of similar material as aircraft windshields and are nearly indestructible.

Polycarbonate is lightweight and stain resistant (but not scratch resistant), provides a high degree of optical clarity and is 50 times more damage resistant than optical glass. This makes it a very powerful, distortion-free lens.

The main drawbacks are a significantly lower degree of scratch resistance as well as visual transparency that is not as strong as optical glass or NXT.

Optical Glass Lenses

Optical glass lenses are ground and polished to the highest quality to ensure distortion-free vision. Optical glass is highly durable and scratch-resistant.

High standards of distortion-free visibility and scratch tolerance are the key benefits of optical glass lenses. The downside, however is that they appear to be more costly and often spider or split affected, which can pose a challenge to active sports.

Frame Shapes

There are countless choices and types of sunglasses available to fit any design or operation.

Aviator / Pilot

aviator sunglasses frame

Aviator/Pilot sunglasses typically have a metal frame that may have a wire around the bridge of the nose. They’re usually big and bold, with huge, oversized lenses.

They typically have features such as UV protection and polarisation. Ray-Ban, Burberry, and Gucci brands are a perfect place to start shopping for the aviator/pilot sunglass frame.

Butterfly / Oversized

butterfly sunglasses frame

Butterfly sunglasses are typically synonymous with the “oversized” design that provides expanded protection around your face. They are also smaller around the bridge of the eyes and nose.

However once you reach the temple section, the frame becomes thicker, resembling a butterfly shape. This sort of frame is a perfect way to show off one’s individuality when making a style statement from the 50’s, which is still considered trend forward in this day and age.

Cat Eye

Cat Eye sunglasses frame

Cat eye shaped sunglasses are distinguished by circular lenses that flare up close to the temples. Many frames have circular lenses with an expanded part of the eye rim drawn inward and outward.

When it comes to this unique cat eye trend ahead picture, the “brows” are the most convincing decorative inventions. This generally means that various sculptural, added and ornamental effects are integrated on the top edges of the cat-eye rims.

If your style is called “retro” then this sort of frame, which became common in the 1950s and 1960s, is just the style you’re looking for. The Versace, Prada, and Burberry brands are a great place to launch your cat eye journey.


Clubmaster sunglasses frame

A concept influenced by 50’s fashion; the clubmaster sunglasses have both a vintage and a timeless look. The elegant style brings the classic wayfarer to new heights by cutting the lower portion of the frame for a semi-rimless look.

The Clubmaster has a massive appeal for both men and women. Two of Ray-Ban and Maui Jim’s leading sunglass manufacturers deliver excellent clubmaster sunglasses.


oval sunglasses frame

Oval shaped sunglasses have pointed corners that are much broader than taller. Oval frames are capable of softening angularity; while the low profile helps the facial features to take centre stage. The oval form frame is suitable for those with diamond or square faces.


Rectangular sunglasses frame

Rectangular frames are defined by a large frame with solid features within the frame. They are both broader and tall, comparable to oval shaped frames. Sharp rectangular frames express a sporty or “bold statement” look, while a rounded edge gives a softer look.

A rectangular form will match several different shapes and types of the face. Looking at Oakley and Ray-Ban is a good start, as both give a wide range of rectangular frames.


rimless sunglasses frame

Rimless frames are sunglasses that don’t have a rim that extends around the frame of the individual lenses. There are a few drawbacks of rimless lenses, one of which is that they weigh less than most glasses and they have less padding.

On top of it the rims don’t block the vision, making it easy to see more. Rimless sunglasses will also draw more focus to the face and eyes and less attention to the real lenses, resulting in a much more subtle appearance.


wayfarer sunglasses frame

Wayfarer frames are built with a form trapezoidal frame and thick rims. This groundbreaking technology was a new creation for the Ray-Ban brand that took advantage of plastic moulding technology and a new robust plastic called acetate that had only just been created in the 1960s.

It’s great for a rebellious, creative thinker looking to take on the world of fresh and revolutionary thoughts.


Wrap eyewear frame

Wrap eyewear stretches outside the temple region to offer maximum coverage security, typically reserved for sportswear. Wrap sunglasses deliver a semi-circular frame that wraps around the head for a panoramic view.

This means that with the wrap goggles, nothing is going to obstruct your peripheral vision.
