Other problems with the eyes

The ability for the eyes to focus ideally is called emetropia, and is when parallel rays of light entering the eye and join at the retina. Individuals with emetropia do not generally need prescription lenses. Prescription glasses are fitted to a person to compensate for visual problems that individual is suffering. Myopia- nearsightedness, or shortsightedness, is when distant objects are blurred. This is caused by their images being focused in front of the retina of the eye instead of on it. Hyperopia-farsightedness, long-sightedness is a condition when the eyeball is too short from front to back. This causes images to be focused behind the retina, thus making object at a distance clearer.

Astigmatism is a condition in which the unequal curvature of one or more refractive surfaces of the eye causing blurred and halo vision.

Presbyopia occurs in most people during the aging process. The eye’s crystalline lens loses elasticity resulting in the inability to focus on nearby objects.

None of these conditions are disease, nor are they life threatening.

Every computer user experiences eyestrain at one point or another.

Most people begin to experience a problem with reading, performing close work, and doing work on their computer at some time in their life. Every computer user experiences eyestrain at one point or another. Perhaps you have a deadline and have been pushing yourself night and day, or perhaps you’re tired to start with and either can’t or won’t take a break.

Generally, we sit further away form the computer screen than we hold a book when reading a book we find we still have difficulty focusing. For many, we simply adjust the viewing options to make the text is larger. However, for many of us, this doesn’t correct the problem. We may notice this problem more when we simultaneously try reading a hard copy and then focusing on the screen.

It becomes obvious for a few computer users that ordinary reading glasses don’t work all the time. For individuals who spend long hours working at a computer this can create serious eyestrain and discomfort.

Many times the problem isn’t with our eyesight, but with our work area, such as bad lighting. Despite that the screen is lit, you need good ambient lighting to avoid eyestrain. This is especially true if you are trying to focus on the computer screen and read a hardcopy.

Glasses designed especially for computer work can help reduce eyestrain, headaches, and blurred vision. Many of the computer glasses on the market are coated with Melanin tint, which reduces the blue and violet light from computers and indoor fluorescent lighting, which can harm your eyes. You may discover that a quality pair of computer glasses will help you make it through the workday with less eyestrain and fatigue.
