Doctors have coined the term “computer vision syndrome” to describe the ways in which marathon screen sessions can lead to blurred vision, eye irritation, headaches, and neck and back pain.

The report pointed out that these eyewear chains distributed false information to customers that linked blue light to increased cancer risk, as well as other eye problems like macular degeneration and cataracts, none of which have actually been linked to blue light exposure.
