The lenses claim to protect your eyes from glare and can help reduce potential damage to your retina from prolonged exposure to blue light. ]]> 2020-09-20 11:51:23 UTC https://padlet.com/s1610017/o3k67il7en2b15y8/wish/761910655 Is it really worth? s1610017 https://padlet.com/s1610017/o3k67il7en2b15y8/wish/761912255 The American Academy of Ophthalmology says you don’t need them and has gone on record as not recommending any kind of special eyewear for computer users. The organization says blue light from digital devices does not lead to eye disease and doesn’t even cause eyestrain. The problems people complain about are simply caused by overuse of digital devices, it says.

“The symptoms of digital eye strain are linked to how we use our digital devices, not the blue light coming out of them,” the AAO says.

Manufacturers claim that blue light glasses can prevent blue light from damaging the eyes. Experts suggest that damage can occur with high doses of blue light but also with a longer duration of less intense exposure.


With the increased use of light-emitting diodes (LED), organic LED, and active-matrix organic LED in technology, people now have chronic exposure to blue light. Experts cannot rule out a yet undiscovered risk of chronic, day-long exposure to LED and blue light.


Some experts suggest that the low levels of blue light emitted from devices are not hazardous, even with prolonged exposure. A 2017 systematic review suggests that there is not enough evidence to support the potential benefits of blue light glasses, and some advertisers have received fines for making misleading claims.
