Visual fatigue: ambient light is often brightness and color variations, long time with ambient light may cause visual fatigue. 2. Dry eyes: If the ambient light is not used properly, some people in pursuit of the effect of the light on the face may accidentally shoot the light directly into the eyes, prolonged exposure will lead to dry eyes. 3. Retinal damage: part of the ambient light intensity is very large, there are a lot of high-energy short-wave blue light, through the lens directly to the retina, resulting in retinal pigment epithelial cell apoptosis, causing permanent damage to the retina. In addition to this, macular hemorrhage, vision loss, blurred vision and pain may occur.
