Here are some advice.

Complete UVA / UVB Protection

Choose sunglasses that provide full protection against ultraviolet light.

Look for a label or a sticker that says one or more of the following:

• Lenses block 99% or 100% of UVB and UVA rays.

• Lenses meet ANSI Z80.3 blocking requirements. (This refers to standards set by the American National Standards Institute.)

• UV 400 protection. (These block light rays with wavelengths up to 400 nanometers, which means that your eyes are shielded from even the tiniest UV rays.)

Choose the Right Hue

The coating that blocks UV radiation is clear in color, darker lens is not necessarily more effective than a lighter one.

But hue does play an important role in vision or color perception.

Yellow or reddish tinted lenses can make it difficult to distinguish the changes in traffic lights.

Gray, green, and brown lenses minimize color distortion, and are a better choice when driving.

Polarized Lenses

Polarized lenses reduce glare by filtering out the reflected sunlight that bounces off surfaces like water or pavement.

They are a good option for sailors, boaters or water skiers, and even fishermen. Polarized lenses is able to cut down the glare from sea surface, flat and smooth surfaces like road pavement, the hoods of cars or class panels.

The downside is that, It can be difficult to read your cell phone, GPS device, or a liquid-crystal display on a dashboard or ATM machine wearing polarized sunglasses.

Polarization has nothing to do with UV protection, check the label before buying to make sure the polarized sunglasses comes with full UV filtering.

Quality of the Lenses

Most inexpensive sunglasses are likely to have lenses that are stamped out of a mold rather than ground and polished, and stamping method can affect the optical quality.

But, that does not mean that cheap sunglasses does not provide UV protection.

Consistency is a concern with lower-priced glasses, some pair offers great clarity and another from the same brand and model might be badly distorted.

To test the optical quality, the FDA suggests focusing on a vertical edge or line. Move your head back and forth, allowing your eyes to sweep across the lens.

If there is any wiggle in the line, the lenses may have an optical defect, you should choose another pair.

Size Does Matter

Wraparound sunglasses offer the broadest protection against UV damage because they block more of the light that hits your eyes from all sides.

Sunglasses with large lenses and wide temples provide the best protection.

Large lenses cover a wider area of your eyes decreased surface area for UV penetration.

The sunglasses that reach down to your cheekbones are a good choice.

Example, Jackie O’s over sized glasses compare to John Lennon’s small,round shades.

Fitness Also Matters

The sunglasses frame and lenses should fit comfortable on your face.

Sun-glass bridge should fit snugly on your nose, temple bar should not be rubbing and the ear hook should not be pinching.

To prevent overhead light penetration, choose a pair that fits close to your face around the brow area, but not too close until your eyelashes are hitting the lenses.

Whether you go for high end designer sunglasses or a more affordable pair sold at the drugstore near your home, choose a pair of sunglasses that is functional.

Importantly, sunglasses the offer protection to your eye health is one sun-glass trend that will never go out of style.
