How to Choose The Best Sunglasses for Yourself

Summary: Summer is coming, which is the hottest season of the year. Whether you like outdoor activities or not, you will also take a series of sun protection products with you, such as sun protection clothes, sun protection caps, sunscreen, sunglasses and so on. I believe many people have a lot of experience in choosing sunscreen clothing, sunscreen hats and sunscreen. Therefore, this article will tell you how to choose the best sunglasses that suit your face shape/type and temperament.

Sunglasses are actually a fashionable item, because they not only give us the functions of sun protection, glasses protection, clear vision, etc., but also bring us more clothing collocation. Just like wearing clothes, some clothes are very versatile, and some clothes are only suitable for certain occasions, so are sunglasses. Before I started selling sunglasses, I have already bought many sunglasses, some of which are unknown brands, some of which are mainstream brands and even luxury brands, and their prices range from dozens of pieces.

Why Do We Need to Wear Sunglasses?

Although summer is the most sunny season, the intensity of ultraviolet rays in spring and autumn is no less than that in summer. Ultraviolet rays with strong penetrating power are reaching the fundus through the pupil. Long-term exposure of eyes to ultraviolet rays will accelerate lens aging and even cause other eye diseases, such as electro-optic ophthalmia, keratopathy, cataract, pterygium, macular degeneration, etc., and leave markings such as melanin precipitation around the eyes. Therefore, the eyes are the parts that need sun protection most, and wearing proper sunglasses is the best eye protection measure.


Can All Sunglasses Effectively Protect Against The Sun?

Because there are many kinds of sunglasses on the market, and their quality is uneven, not all sunglasses can effectively protect against the sun.

Ultraviolet light can be divided into three types: A-ray, B-ray and C-ray, which are called UVA, UVB and UVC for short, and their wavelength ranges are 400-315nm, 315-280nm and 280-190nm, respectively.

A good UV protection lens should eliminate UVA and UVB rays in the wavelength band of 280-400nm. They are usually marked as "UV400" or "UVA/UVB protection". However, ordinary optical resin lenses are generally UV-resistant to UV360-380, which can prevent more than 95% of ultraviolet rays, so that they can block most of the daily ultraviolet rays. Some low-priced and inferior sunglasses on the market, instead of protecting the eyes, may damage them. Therefore, the choice of big brands or sunglasses with guaranteed quality (such as Gentle Monster, Gucci, Exlanss, Ray-Ban, Armani, BVLGARI, MontBlanc, Chanel, Beneunder and so on) can meet the national standard of SPF, protect our eyes, be beautiful, fashionable and durable.

Tip: Regular sunglasses brands will clearly identify the UV logo, so it's right to look for the UV400 logo when purchasing.


What Are The Classifications of Sunglasses?

Sunglasses can be divided into polarized sunglasses, unpolarized sunglasses and sports/eye protection sunglasses according to categories.

Polarized Sunglasses

Polarized sunglasses can be divided into: fishing glasses for daily non-competitive use and polarized driving glasses.

Polarized sunglasses, which are relatively weak in UV protection, are used when the line of sight clarity is high, especially when we are driving, and need to be used to prevent the head-on headlights from dazzling. When fishing enthusiasts are fishing, it's easier to watch the drift with polarizer and their eyes are not tired.

Unpolarized Sunglasses

Non-polarized sunglasses are mainly used to block strong light and ultraviolet rays. Because of their more casual design, non-polarized sunglasses are more suitable for daily wear.

Sports Sunglasses/Goggles

Safety glasses worn in sports, usually advanced equipment has the effects of safety (PC lenses), protection (TR-90 frames, both soft and elastic), comfort (anti-slip nose pads and foot covers) and beauty (matching sports and leisure clothes). Riding glasses, ski glasses, outdoor sports glasses and golf glasses are the main ones.


How to Choose Sunglasses for Different Faces Shape/Type?

Accurately measure your facial data. To determine which face shape you belong to, you need the following four pieces of data:

Tip: This method is unisex.

  • The vertical distance from the middle hairline to the chin
  • The distance between two eyebrow peaks or brow bones.
  • The distance between the cheeks of the face
  • Arc length from chin to below ear


How to Choose the Lens Material of Sunglasses?

Regarding the choice of lens materials, this aspect should be the blind spot in the choice of sunglasses. If you choose myopia glasses, users will pay great attention to this point, but few people will pay attention to it when you switch to sunglasses. In fact, this is an important factor to distinguish inferior glasses.

Wearing inferior sunglasses may deepen myopia. It is recommended that you choose PC lenses, TAC polarized lenses or nylon polarized lenses.

PC Lens

Not only is the anti-impact effect particularly good, but it is also very lightweight and durable, especially suitable for traveling, which is convenient to carry and not easy to be damaged.

TAC Polarized Lens

It is often used on children's sunglasses, because this kind of lens can block dizzy light while resisting ultraviolet rays and strong sunlight, making the vision clearer and softer, and better protecting children's eyes.

Nylon Polarized Lens

Many high-end sun-eye brands will adopt nylon polarized lens material, which not only has super high definition, but also can sort out the messy light from all directions into the same light as the horizontal direction of the eyes, so that you can wear it more comfortably and better protect your eyes.


How to Choose the Lens Color of Sunglasses?

90% of people think that the darker sunglasses are, the better they can block ultraviolet rays. In fact, this view is wrong. The depth of the lens color will only affect the visible light received by the human eye, but the ultraviolet light is invisible, so it has nothing to do with the transmittance.

In other words, some transparent lenses can also block ultraviolet rays because of their material properties and special technology, while some inferior sunglasses, which look dark in color, may not be able to block ultraviolet rays. Therefore, when purchasing sunglasses, the most important thing is to see its function clearly.

The depth of lenses is related to the transmittance, and the most common ones are gray, tan, dark green, yellow and orange, etc.

  • Gray Lenses: strong sunlight, daytime driving, cycling, fishing, etc.
  • Brown Lenses: golf, tennis, daytime driving, cycling, resisting the fierce sunshine, etc.
  • Green Lenses: protect against the fierce sunlight, driving during the day, riding a bike, etc.
  • Yellow/Orange Lenses: cloudy days, tennis, shooting, etc.

In addition, polarized sunglasses can selectively filter sunlight reflected from snow, water and beach, which is very suitable for skiing and most water activities.
