Sunglasses serve a greater purpose than simply reducing sunlight. Beyond visual comfort, they provide crucial protection and optimize visual function, especially for the visually impaired. It’s not just about light transmission; it’s about how the lens enhances their vision. Introduction: Sunglasses can be transformative for those with visual impairments. While many see them as a…
Sunglass lenses should be able to: reduce glare and haze to provide clearer, sharper vision, enhance color definition, reduce reflections off the lenses, and most importantly, 100% UV protection. If you have read the other posts on Lens Technology, what you may have realized is that sunglasses are more than a tint used to decrease…
Decreasing light levels with a tint may give a greater level of visual comfort, but may not offer enough protection against wavelengths of light known to be harmful to the sensitive tissues of the eye. Specifically, protection from the high energy, damaging, short wavelength UV light. Lens materials such as plastic and poly carbonate have…
Tints not only vary in color, but also vary in transmissibility. The amount of light that is transmitted is the amount of light allowed to pass through the lens. The darkness of the tint does not indicate it’s capability to protect against harmful UV light. While you may think that sunglasses are just glasses with a…
