But there is a great alternative to glasses – contact lenses, which perform both corrective and aesthetic functions. The availability of these products has made them very popular among a wide range of consumers, but unfortunately not everyone has knowledge about their quality characteristics.
Contact lenses are divided into rigid and soft, depending on the material they are made of. Rigid lenses, made of silicone polymer and used for the correction of astigmatism, can put a slight pressure on the cornea of the eye. While soft lenses are more elastic and, when put on easily, take the shape of the cornea.
The main advantage of contact lenses is that they do not limit the field of vision at all and allow you to see objects very clearly even with a high degree of ametropia. In addition, unlike glasses, contact lenses protect the eyes in case of injury. So, if a person who wears glasses risks breaking the lenses and injuring the eyes when falling, then the one who prefers contact lenses to glasses can avoid such troubles.
Contact lenses also differ in design. Spherical contact lenses are intended for the correction of hyperopia and myopia, astigmatism is corrected by toric contact lenses, and presbyopia, or as this disease is commonly called senile farsightedness, is corrected by multifocal contact lenses.
But the purpose of contact lenses is not limited only to vision correction, although this function is a priority in the innovative development of these products. There are cosmetic contact lenses designed to correct congenital or acquired defects of the eye. But the most popular among young people are decorative contact lenses, which can give the natural color of the eyes a certain shade depending on the color of the lens.
Such colored lenses can be worn by people with perfect vision, they are absolutely harmless, and their variety gives a special charm to the owner of any eye color. A blonde with brown eyes can easily 'turn' into a blue-eyed beauty with the help of colored contact lenses and vice versa. It is noteworthy that fantasies about experiments with colored lenses are multifaceted, and at the same time, the owner of such products does not experience discomfort or eye fatigue when wearing them.
