A new product range of lenses from Zeiss aims to offer improved blocking of blue light wavelengths, tackling a recognized health issue for people spending extended periods of time working via screens.
Zeiss BlueGuard lenses incorporate wavelength-blocking material into the lens material itself and block up to 40 percent of incident 400 to 455 nanometer light, according to the company.
The ill-effects of excessive exposure to blue wavelengths from screens and displays has been studied for some time, but the Covid-19 pandemic has exacerbated the problem by compelling many people to incorporate online working with their domestic media consumption.
