Several Bad Habits of Watching TV Harm Eyes

When you do like this, the contrast of light will be very high. If this continues, the eye vision will be badly influenced and get harmed.

Switch the TV programs frequently.
According to a new research, compared to watching TV for a long period, to switch the TV programs is more harmful to the eyes. The changing moment is the very time of having the most stimuli. The screen would turn black and again light up suddenly; and at this moment, the sudden change of light will stimulate the eyes.

Nowadays, there are TV sets on most of travel buses. Owing to the limited space and the vibration of buses, it could be installed the TV sets of size 14. Despite that, the body of travel buses is often rather long, and the angles for watching TV is not ideal. The scientific sayings suggest that the distance between people and TV sets should be 4 to 6 times as long as the diagonal line of the screen and the angle should not be less than 45 degrees. In the travel buses, the condition could not meet the requirements. Under such condition, the eyes could be easily harmed. In addition to this, the running bus sometimes causes the unclear TV vision. After a period of time, the eyes suffer from pains, the vision becomes unclear, and even there will be headache, nausea, and other discomfort, so it is better to reduce the time to watch TV on the bus.
