Which color is better for protecting eyesight?

Everyone should pay attention to protecting their eyesight, because watching TV, using computers or playing with mobile phones for a long time can easily affect our eyesight. So you can look at more blue or green plants to improve your eyesight and fatigue.

1. Excessively bright colors can make people feel tired, while overly dark colors can make people feel heavy; red and yellow can give people a dazzling feeling, while cyan and green can bring people a cool and calm feeling. Different colors absorb and reflect light differently. Red reflects 67% of light, yellow reflects 65%, green reflects 47%, and cyan only reflects 36%. Since red and yellow reflect light more strongly, they are prone to glare and are dazzling. Cyan and green have moderate absorption and reflection of light, so they are more suitable for the human nervous system, cerebral cortex and retinal tissue in the eyes. Therefore, people usually feel more comfortable with their eyes when looking at green or cyan colors.

2. Cyan and green give people a cool and calm feeling (moderate reflection of light). The cyan and green colors of grass and trees can not only absorb the ultraviolet rays in strong light that are harmful to the eyes, but also reduce the glare caused by strong light to the eyes. Therefore, staying close to cyan and green colors can protect the eyes.

3. Green is less stimulating and easier for the eyes to adapt. Green and cyan have shorter wavelengths, and their absorption and reflection of light are moderate, causing no adverse stimulation to the human nervous system, cerebral cortex, or retina in the eyes. Taiwanese researcher Lin Youshi said this based on foreign research results. (Because green is in the middle of the spectrum and has a shorter wavelength, it makes people feel more comfortable)

4. Looking at green can relax the ciliary muscles of the eyes. When looking at yellow, the human eye focuses directly on the retina, and when looking at red, it focuses behind the retina (the ciliary muscle needs to work harder than when looking at yellow to pull the focus to the retina). But when looking at green, the focus is in front of the retina (the ciliary muscle is more relaxed than when looking at yellow), and the image is also in front of the retina, so the eye's accommodation function can be relaxed. When looking at green, the ciliary muscle is also more relaxed than when looking at red and yellow. The ciliary muscles of the eyes thus get a rest, reducing eye fatigue.

5. Blue can stabilize emotions, relax the mind and relieve fatigue. Looking at blue, which is also a cool color, such as the sky, can relieve symptoms of eye fatigue. Blue can not only stabilize a person's mental state, but also lower blood pressure, stabilize breathing and relax muscles. Blue can free people from a state of tension and anxiety. In addition, light blue has the effect of stabilizing emotions and reducing fatigue, while dark blue has a more significant calming effect.
