Macular degeneration is a common problem faced by our middle-aged and elderly people. Blue light on mobile phones is generally considered to be an accomplice in causing visual fatigue, blurred vision and macular problems in modern people.
Regarding this blue light (especially harmful blue light within 400 to 440 or 450 nanometers), there are reports exaggeratingly claiming that the potential hidden threat of blue light radiation to humans will far exceed the destructive effects of Sudan red, melamine, SARS, and H1N1. Although this statement is a bit exaggerated, looking at blue light will not cause particularly serious damage, but now the time spent on a mobile phone for a few hours has a great impact on the eyes.

The mechanism by which the macular pigment composed of lutein protects the retina can produce a shield-like effect on the blue light that damages the eyes. There are two commonly accepted conclusions in this regard:
1. Lutein can absorb a large amount of blue light close to ultraviolet light. Therefore, the macular pigment may filter the blue light that damages the photoreceptors and the retinal pigment.
2. As an antioxidant, it has antioxidant activity and limits tissue damage caused by metabolism and light. It may be used as an antioxidant to protect the macula and reduce short-wave visible light damage.
Therefore, we can be optimistic that the effective way to treat and prevent macular degeneration or damage is to supplement lutein.
