päikesekaitseprillid

Päikesekaitseprillid, which translates into English as sun‑protective sunglasses, are eyewear designed to shield the eyes from harmful ultraviolet radiation while enhancing vision comfort in bright conditions. They were first popularized in the early 20th century when motor racing and the emerging leisure industry demanded high‑performance eye protection. Modern models incorporate advanced lenses that block 99 to 100 percent of UVA and UVB rays and are available in a wide range of colors, tints, and optical densities.

Common lens technologies include polarized, photochromic, and mirrored coatings. Polarized lenses reduce glare from reflective surfaces such as water or pavement. Photochromic lenses darken automatically when exposed to sunlight. Mirrored coatings reflect a portion of visible light, further reducing brightness. Beyond optics, the frames are constructed from materials such as acetate, metal, polymer, and natural composites. Acetate frames offer flexibility and a lower cost, while metal frames provide durability and higher weight‑bearing stability.

Choosing appropriate päikesekaitseprillid involves evaluating lens colour against environmental conditions, confirming UV protection levels, and ensuring a comfortable frame fit. When worn correctly, these glasses reduce the risk of cataracts, photokeratitis, and other eye disorders while improving visual clarity and reducing eye fatigue.
