Eye Master is used for reducing the risk of near sightedness. The device is comprised by emitting signals, receiving signals and a time computing system to reduce the risk of near sightedness for reading, writing or looking at a computer screen. The emitting part is fastened near the user’s eyes by means of a hat belt. The receiving part is located inside of a pen container near the book, writing paper or the computer screen. The device sends two kinds of signals to the receiver. There will be a delay time between the two signals when the signals have been sent to the receiver. Then the distance between the emitter and the receiver will be calculated according to the delay time of the signals. The device will generate different short sounds to warn the user if the distance is improper. The advantage of this device is that the body of the user will not be exposed to any active signal such as an infrared light, radio or ultrasonic signal. It is a totally safe device.

Near sightedness is a condition where a person can see close objects very well, but have difficulty seeing objects that are far away. Objects that are far away will appear blurry to people who have nearsighted vision.

Improper reading or writing habits is possibly the commonest cause of nearsightedness in childhood. This device is used to keep a proper distance between the user’s eye and the object in order to reduce the risk of near sightedness.
