Are there any permanent Direct damage from digital screen usage in general? This article is citing a paper that suggests the blue light may cause macular degeneration and they haven't tested in human eyes yet. Another study talks about eye damage from blue leds. Are there any proven studies addressing the blue light produced from smart devices? Any studies about the UV light generation from smart devices(I've read that UV rays are not emitted from digital screens but I couldn't find any paper supporting the claim)
Should we be concerned about the blue light from screens when compared to other sources of the blue light like- fluorescent lamp and Sunlight?
