Until recently, we wore Essilor Crizal Prevencia computer glasses - the best we could find. They cost about €80.00 from a French optician. Now we wear ScreenTech computer glasses. They are noticeably better. And they cost only £39.97!
Computer glasses should be labeled 'UV400.' According to one manufacturer, this is what distinguishes more expensive computer glasses from "cheap" ones. As a result, all of our computer glasses are UV400.
All of our computer glasses can be worn over another pair of glasses. Alternatively, you can get an 'Essilor' coating on prescription lenses. Or non-prescription or prescription lenses under the Crizal® Prevencia™ label. But these options are much more expensive.
One of the benefits of having a separate pair of computer glasses is that they are best worn only while you are at your computer or tablet – we need some natural blue light getting to our eyes. People who wear blue-blocking glasses all the time start exhibiting new problems in their energy. This can result in less energy, lower mood, reduced creativity and/or weaker immunity.
If you want the best eye-protection during the day - not to mention maximum blue light-reduction for 2 to 3 hours before bed, for better sleep - ScreenTech computer glasses are your best choice.
