A special computer mouse has been developed here in Korea to help those with severely poor vision read better.

Researchers at the department of ophthalmology of Seoul National University say they have developed a computer mouse equipped with a special camera lens that can blow up letters or images on the screen for up to 50 times.

One of the researchers who developed the device has lived with poor eyesight all his life. The special mouse can be connected to all kinds of home appliances that provide images, such as televisions and computers.
