Short Answer

There is no clinical evidence that digital screen blue light causes retinal damage or blindness.

Detailed Explanation & Evidence

The American Academy of Ophthalmology (AAO) states clearly that the blue light emitted from digital devices does not cause eye disease or retinal damage. The sun emits vastly more blue light than consumer screens. The actual cause of post-screen discomfort is digital eye strain (dry eyes from decreased blinking frequency), which is resolved with the 20-20-20 rule.
