Sunglasses protect our eyes from bright sunlight and also serve as fashion accessories. When choosing sunnies, many factors need to be considered, such as function, style, price and durability. Thanks to online shopping, trendy sunglasses are available at reasonable prices. However, you may be confused by all kinds of different lenses. Let's explore the pros and cons of various shades.
UV protection sunglasses

· UV coatings block the sun's harmful UVA and UVB rays from damaging your eyes.
· Sunglasses that offer 100% UV protection may filter out blue light as well.
· The lens only protects your eyes from the front. You'll still need extra protection like wearing a hat.
· The UV protection in sunglasses will decrease, but it will take years to do so. Replace your eyewear every several years.
