Understanding Sunglass Coatings
Different sunglasses come with various coatings that significantly impact how they protect your eyes and how you see the world. Let’s explore some of the most common types of coatings and their functions.
Anti-Reflective Coating
Enhanced Light Transmission
An anti-reflective coating is frequently applied to eyeglasses. This coating minimizes the amount of light reflecting off both sides of the lenses, thereby increasing overall light transmission. This is particularly beneficial for prescription lenses. While it may reduce some environmental glare, its primary function is to enhance light transmission and minimize glare from the lenses themselves.
Polarized Lenses
Reducing Glare
Polarized lenses are common in sunglasses designed for various sports but are also ideal for anyone spending significant time outdoors. These lenses filter light to significantly reduce or eliminate bright reflections from surfaces like water, ice, snow, glass, or metal. While they make the world appear sharper and slightly dimmer, they can distort the appearance of electronic screens.
Protection in Bright Environments
Polarized lenses help protect your eyes in very bright conditions. However, they do not inherently provide UV protection. Always check for a label indicating UV protection. All polarized lenses mentioned here offer both glare reduction and UV protection.
UV Protection
Shielding from Harmful Rays
Sunglasses should protect your eyes from more than just bright light; they should also shield them from ultraviolet (UV) light. UV exposure can lead to long-term vision issues, including cataracts and certain eye cancers. The American Academy of Ophthalmology strongly advises using sunglasses with UV protection.
Ensuring Complete Protection
With the appropriate coating or materials, sunglasses can offer nearly complete UV protection. Polycarbonate lenses naturally provide UV protection without additional coatings. Always look for a sticker indicating “100 percent UV protection” or UV400 protection to ensure the sunglasses have been tested for UV protection. All sunglasses listed here offer 100 percent UV protection.
