Sunglasses are more than just an accessory that makes a style statement. They protect the eyes from the sun's UV rays, glare and headaches, and also prevent premature aging of the fragile skin around the eyes besides preventing the eyes from watering and squinting.
Keeping all the following points in mind is essential when purchasing shades:
• Ultraviolet protection - Sunglasses should ideally protect the eyes from both UVA and UVB rays, so look for those labelled UV400.
• Polarized lens protection - Polarized lenses reduce glare from surfaces like water, glass and snow. They are a smarter option than your regular tinted glasses as they help the wearer see way better.
• Lens tint - Tinted lenses provide great protection from the sun's glare as these absorb the light passing through the glasses. Different tints provide different benefits, e.g. grey lenses reduce brightness; brown, amber and green lenses reduce sun glare (but these distort colors); yellow lenses sharpen images; and rose lenses provide a good contrast for objects viewed against blue or green backgrounds.
• Polycarbonate lenses - Whether the lenses are tinted or polarized, make sure they are polycarbonate as they are shatter resistant.
• Fashion - Trends come and go, but classic styles stay. Let your choice be dictated by the shape that best suits your face. Try to avoid frames that are heavy as these can cause headaches. Frames made of titanium are a good bet because they are light, durable and flexible.
• Frames made of titanium are light and durable
• Opt for polycarbonate lenses that are shatter-proof
• Polarized lenses work to reduce glare from surfaces
