Sunglasses are both an accessory and a practical item. Shape and colour can express your style, but appearance alone cannot tell you how much ultraviolet protection the lenses provide.
Look for the label
The American Academy of Dermatology recommends choosing sunglasses with UV protection and notes that dark-looking lenses do not necessarily provide it. Read the product label and the seller’s specifications rather than judging by tint alone. Requirements and labelling standards can differ by market; use a reputable retailer and ask for clarification when a claim is unclear.
Try the fit
The frame should sit comfortably on the bridge of your nose and around your ears without sliding or pinching. Try moving your head and check that your eyelashes do not touch the lenses. Larger or wraparound shapes can offer more coverage around the eyes, according to the Academy, although comfort and proper fit still matter.
Build an outfit around them
A slim frame can feel understated, while a larger shape can become the focal point of a simple outfit. Choose a case you will use and clean the lenses according to the maker’s instructions. Sunglasses complement other sun-protection measures; they do not replace shade or protection for exposed skin.
