Blue Light Glasses - Pretavoir Opticians Online
UV and blue-violet light are present everywhere: outdoors due to the sun and indoors due to artificial light and electronic devices such as cell phones, tablets, and laptop computers. As most people are at risk of overexposure to harmful light in their day-to-day activities, Blue Light glasses with coatings such as Prevenia, Blue Max and Blue Control aim to offer a solution to improve eye protection.
From Essilor, Crizal Prevencia lenses are the result of several years of research in collaboration with the Vision Institute in Paris, France. By gathering expertise in the areas of cellular biology, physics and photometry, this research led to the identification of a precise spectrum of light wavelengths toxic to retinal cells. Based on this discovery, they developed the first clear lenses that selectively filter blue-violet light and contribute to preventing its harmful effects on the eye.
From Zeiss, Blue Protect UV offers excellent Blue Light protection aswell as blocking UV light from causing any premature ageing of the eye.
From TruOptics, their excellent Blue Max helsp selectively block blue light whilst allowing all other wavelengths pass through.
Each of the Blue lens coatings also have a slight lens filter which provides a calming infuence on your visual comfort.
