There are various kinds of computer glasses. The simplest computer glasses are made of single vision lenses. The lenses are designed for intermediate range for viewing the computer screen. Normal reading glasses are designed for near range, whose viewing distance is longer than what computer screen needs. As a result, normal reading glasses are not good for computer use. What's worse, some even lean forward with normal reading glasses to compensate the distance, causing backaches and neck pains. Overtime, this can be very serious. For a good protection and healthy life, computer glasses are indispensable.
Some computer glasses are specially made for different purposes, such as bifocal computer glasses. These computer glasses have different segments in the lenses. The upper side is designed for viewing computer screen while the lower side serves to read reading materials at a closer range. If your work requires reading materials while keep working at a computer, bifocal computer glasses will be suitable. A pair of computer glasses will not cost too much, but they can protect your eyes from computer radiations and enable you a better sight. Computer glasses can also reduce glare that make our eyes more difficult to see clearly. For a better and safer life, make computer glasses your safety-ensuring equipment.
