Today, colored lenses, black, are not only an object for vision correction, but also a stylish accessory. However, contact or scleral lenses were not widely available until the mid-1990s.
Initially, this type of optics was developed for people suffering from hypersensitivity of the eye. To this day, with such diseases as microophthalmia, aniridia, keratoconus, transparent degeneration, scleral lenses are indispensable. They are also essential in case of surgical complications and chemical eye burns. They are made from special polymers, which are characterized by good oxygen permeability. Despite the therapeutic effect, the scleral lens, due to the presence of the tunnel effect, can distort vision in a person with normal vision. Therefore, the restrictions on wearing them include the minimum time (no more than 6 hours a day, or even less) and a ban on driving vehicles.
It is known that black lenses have firmly entered thecinema of the whole world, and they were the first to be used in Hollywood. But the actors didn’t feel much pleasure at the same time, since working with such optics means giving an additional load on the eyes, and this is very tiring and subsequently impairs vision.
Modern black lenses are safe, by purchasing such a product, you can be sure that the color of the eyes will change dramatically, but at the same time it will look absolutely natural. With such lenses it will be convenient in any situation. And except for the black color of the eyes of those around you, you will not be surprised by anything.
Black lenses for the whole eye are slightly different in properties. They are designed for various theatrical performances or costume parties, Halloween celebrations or any other entertainment where a significant change in the traditional image is required. Black lenses will help the wearer to put the final accents when creating a certain image (for example, an alien or a vampire). Yes, and others will not disregard such a character. For a person who tries on such optics, the perception of the surrounding world will not change, since the central part of the lenses is transparent. However, a variant of deterioration in visibility is possible with a sharp expansion of the pupil. It can be bright sunlight or an excited state. Then part of the pupil falls under the colored zone and visibility is slightly limited.
Wearing and caring for such optics as black lenses is no different from ordinary ones. But ophthalmologists say that withoutspecial cosmetics are indispensable here. In addition, be sure to pay attention to possible contraindications and the expiration date at the time of purchase.
Despite the fact that for the first time scleral lenses were available to the general public in the US, they are now illegal to sell there. After all, infections introduced when using black lenses easily cause blindness. You can buy such optics from us only in the online store. But before buying, you should think again. Maybe he alth is more important? After all, each person has his own physiological characteristics, and what is convenient and comfortable for one is unacceptable for another.
