Buying Sunglasses



Factors To Consider When Buying Sunglasses


A quality pair of sunglasses can help keep your eyes healthy and your vision clear. Here are some factors to consider when purchasing your next pair.


UV protection


When choosing sunglasses, UV protection is non-negotiable, as the sun’s ultraviolet rays can permanently damage your eyes. Sunglasses should have both UVA and UVB protection and should block UV wavelengths of up to 400 nanometres.


Don’t be fooled by dark or mirrored lenses; they don’t necessarily provide UV protection. Dark lenses without UV protection are even more dangerous than wearing no sunglasses at all because the low light will cause your pupils to dilate, allowing more UV rays to enter your eyes.


Size


You want the least possible amount of UV light to enter your eyes, and you should shield them from the sun by choosing sunglasses that are the appropriate size. Large shades will cover more of your face and better protect your skin and eyes. A wrap-around pair is the most beneficial, as it will protect your eyes from the sides as well as the front.


Color and tint


Grey-tinted glasses will reduce overall brightness with little color distortion, while amber-tinted glasses can enhance depth perception in low-light situations.


Mirrored lenses work well to decrease the amount of light that enters your eyes. Gradient lenses are darker on the top than the bottom, and can be advantageous for driving and everyday use, but won’t work well at the beach, on a boat or while skiing.


Quality


Check the quality of the lenses by holding them at arm’s length. Look through the lenses at something straight in the distance, such as a door or window frame. Then, move the glasses horizontally and vertically. If the straight edge of the door frame distorts, curves or sways, the lenses are of poor quality.


Polarization


Polarization is different from UV protection. Polarized lenses offer increased protection from the glare off surfaces such as water or snow. The lenses have a chemical applied to them that blocks some of the light from passing through and subdues blinding glare. Polarized lenses are beneficial for driving, boating and winter activities.
