Experts have downplayed speculation that there will be a significant upswing in blindness in three to five years, caused by exposure to blue rays.

A recent article titled “Warning: blindness to breakout on a large scale within 3 to 5 years” stated that viewing high-frequency blue rays increases the risk of eye diseases.

However, experts have pointed out that only those exposed to the high frequency and energy for a long period of time will experience retina damage. There is a major difference between the exposure reponsible for significant damage and that present in most people's daily living environments.

Blue-ray is, to a certain extent, detrimental to people’s eyesight, but not all blue rays are harmful. In daily life, blue rays are contained in, among other things, flat panel displays, fluorescent lights, liquid crystal displays (LCDs) and phone screens.

Liu Hongwei, associate research fellow at Beijing Institute of Ophthalmology, stressed that people have built-in protection mechanisms to defend against light damage. What's more, the body's antioxidant system can protect against damage from blue rays. According to Liu, the key is simply to stay away from excessive and unnecessary exposure.

Experts suggest that people pay special attention to light sources in their daily lives in order to limit exposure. Protective blue-ray glasses should be worn only under the guidance of a doctor.
