Spectacles

The most widespread method of shortsightedness correction is spectacles. With all their advantages spectacles bring a lot of inconvenience to their owner: they get dirty all the time, steam up, sli off from the bridge of the nose, prevent from going in for sports or just engage in physical activity. In order to avoid the overstrain of the eyes spectacles are chosing by the 8th line of the table and, as a result, do not provide 100 % of teh eyesight. They limit the side vision greatly, affect the stereoscopic effect and space perception, which is especially important for drivers and in case of an accident the broken lenses can cause a serious trauma. Besides, the incorrectly chosen spectacles can be the reason for the constant overstrain of the eyes and gradual development of eye diseases connected to it.
