The use of corrective eyeglasses or contact lenses is sometimes considered to worsen eye tension on a regular basis
. On the other hand, both nearsightedness and farsightedness are thought to be caused by vision tension. The eyes muscles need proper rest and relaxation during daily usage. This is also true for the rest of the muscles around the body. During the recent years, the importance of relaxation for ocular health is being increasingly recognized. Many eyewear users may be indulged in the fact that these magic eyeglasses or contact lenses easily help them restore normal vision. However, the use of corrective devices will actually increase the amount of exercise the eyes have to do, resulting in visual deterioration. This is not a tale but a real fact, testified by the fact that most wearers need to buy new glasses or contacts with a stronger prescription.
The most important thing the eyes should receive is eye exercise. In fact, there are a number of eye exercises that can reduce eye strain and improve eye relaxation. The majority of these exercises only need to be maintained five minutes every day. Over time, eyesight will gradually improve. The simplest form of eye exercise is to look out the window. The twenty-first century is witnessing the rapid development of the PC industry that more and more jobs and occupations rely on the use of a computer. Spending a lot of time indoors or working at a computer is very easy to cause eyestrain. It is widely encouraged to look out the window for several minutes after two or three hours of indoor working.
Another eye exercise is to look up as far as possible with the body sitting or lying down for five seconds. The next step is to make the eyes to center again for a few seconds. And then look down for another five seconds. Similar steps involve looking to the left and the right repeatedly. Palming is another type of eye exercise that is also widely recommended. These eye exercises discussed before are centrally focused on the eyes. Full body relaxation is also beneficial to the eyes.
