As temperatures rise, many people start wearing sunglasses when going out. But do your sunglasses really protect your eyes? In fact, not everyone knows that choosing sunglasses is quite a science. Poorly selected sunglasses may even trigger glaucoma. So what kinds of sunglasses are best suited for summer? While style and comfort play a big role in choosing the right pair of sunglasses, the right lenses can also make a big difference.
Different optical lenses offer different levels of protection, so you can choose the right lens based on your personal needs.
1. Tinted Lenses
During production, chemical substances are added to give the lenses color, allowing them to absorb light of specific wavelengths. This is the most common lens type for prescription sunglasses. But please note that darker lenses don’t automatically offer more protection. Look for 100% UVA/UVB protection when you buy sunglasses.
2.Photochromic Lenses
Photochromic lenses, also known as “photosensitive lenses”, contain silver halide chemicals. These clear, colorless lenses darken into tinted lenses when exposed to strong light for eye protection, making them suitable for both indoor and outdoor use. So photochromic lenses act as both prescription glasses and sunglasses, offering a convenient, all-in-one solution that protects the eyes from the sun’s UV rays and reduces glares and blue light.
3. Polarized Lenses
Polarized lenses are special lenses coated with a vertically oriented special film that only allows light traveling in one direction to pass through. They filter out harsh, parallel glare reflected from sunlight on water, land or snow, softening the light for comfortable vision and reducing glare for clearer object viewing. Polarized lenses can alleviate glare from asphalt roads, glass walls, water surfaces and snow, eliminate reflections and glare, enhance color contrast in scenery, and provide excellent resistance to strong light.
Sunglasses were not created merely for fashion; wearing them is an effective way to protect your eyes from UV damage. You can get more details about Universe sunlens by https://www.universeoptical.com/sun-lens/
