Colored lenses

Colored lenses.

Colored contact lenses are associated with fashion. And not by accident. They really can radically change the face of the person. But the scope of the colored lens is wider and often includes medical factors.

Statement

Colored soft contact lenses:

  • Help to cope with the so-called thorn — defect that gives women a lot of experience. The lens, which imitates a black pupil, hides this flaw.
  • Cope with the manifestations of diseases in which there is no part of the iris or change the color of one of the sectors of the iris. In this disease, a special lens with iris painted not only the "mask", but also improves the quality of vision.
  • Apply in case of intolerance eye to sunlight. Such lenses are much safer to shield your eyes from harmful radiation than glasses with tinted windows.
  • By using colored lenses resort with amblyopia ("lazy eye"), to provide a visual load a patient eye. Much easier to "close" the eye lens that prevents entry of light than the old seal the glass on the glasses.

In these cases, ophthalmologists for over ten years using colored contact lenses. In recent years, multi-colored lenses acquire aesthetic value and are often used for cosmetic purposes.

Pick their own contact lenses is undesirable for several reasons:

  • a prescription for contact lenses differs from prescription for glasses. It should include information on the radius of curvature and diameter of the optical power of the contact lens.
  • procedure of selection of colored contact lenses may be slightly different from the conventional technique of selection. The most important element is the proper selection of the so-called centering. It helps to achieve matching between the transparent lens and the pupil area of the eye pupil as well as between lenses and the colored iris area. For all colored contact lenses cosmetic effect will be better, more accurate alignment.
  • It is important to know that contact lenses are contraindicated for people with chronic diseases of the upper respiratory tract.

Forms

All colored contact lenses are divided into two groups:

  1. translucent tinted or "enhancers"
  2. opaque.

The first group includes tinted lenses, which is also called ottenochnymi. They have poor color and give a more intense shade of the natural color of the iris of light eyes. Green eyes can be turned into turquoise, blue — in blue. But with the help of lenses you can not brown eyes "change" in blue or blue to green. Tint lenses have a weak uniform color across the surface of the lens than the peripheral portion, which is transparent in order to hide the edge of the lens against the sclera. Thus, the colored zone diameter slightly less than the diameter of the lens.

The second group — opaque lenses— Able to perform a miracle. Such lenses — bright, dense and intense in color — change any eye. Due to the absorption of light in the pupil area dyes such lenses remain transparent to ensure normal vision. The most natural form is obtained when the lens has "painted" iris of the human eye, with its shimmering color and a dark rim. In these lenses with rim eyes look more attractive and expressive. Tint lenses are addressed bright-eyed. They give a bright, rich and luscious color eyes, but in practice can not change the color of dark eyes. Opaque lenses will change the color of any eye, even the darkest.

The American magazine "Science Digest" published an interesting study of eye color matching human nature.

Recently, a very popular decorative contact lenses. At one time they were sold only as accessories for theatrical performances. With their help, we obtain the "cat" eyes, "thorn" eyes "vampire", "alien", "zombie", and many other characters.

Now decorative lenses are no longer the prerogative of cinema. On these lenses may show stars, hearts, and even a dollar sign. There lenses which have the effect of phosphorescent eyes. The most popular car black crosses instead of the iris and the pupil, which periodically erupts spark (but it's just an optical illusion).

Many companies produce colored contact lenses. Each manufacturer tries to cover the entire scope of opportunities offered by the different staining techniques. In other words, almost every series to be released by the same manufacturer, you can find a lens color intensity, "overpowering" even darker natural color of the iris. Typically, each model series comprises 5 to 15 color variations. From the usual brown, blue, gray, green to exotic turquoise, violet, sapphire and even the colors of fallen leaves.

Terms of use

These lenses have a number of features. Because of a dye having an oxygen permeability of such lenses is extremely small. Therefore, you can wear them continuously up to 2-3 hours. Although the carnival lenses are designed for a month, experts believe that the best way to avoid complications with their use — wear once and then thrown away.

Testing the lens in this category, doctors performed a comparative study of patients using conventional soft contact lenses, and for fans of the carnival lenses. The experimental results showed that the decorative contact lenses in patients was significantly reduced visual acuity, contrast sensitivity, narrowed field of vision.

Using the lens of intense color, it should be remembered that the diameter of the pupil in some cases may exceed the diameter of the central zone of the lens unpainted. Because of that in some areas of the field of view of the image can be a bit vague. This effect is more common in low-light conditions, such as when watching a movie in a movie theater or while driving in the dark.

Lenses and cosmetics

If you wear lenses while using cosmetics, you need to remember a few rules:

  • Packaging should be the mark that the ink was ophthalmologic control, and the shadows fit ladies wearing contact lenses.
  • It is advisable to mascara, eye shadow and powder was finely divided and most dense.
  • Particular attention should be paid to the mascara. Very careful to choose the volume and lengthening mascara — it is composed of microfibers. They can come loose from the carcass and get into the eyes and under the contact lens. In this case, the ideal — mascara with nylon fibers.
  • Try not to overload the face makeup. Only apply mascara to the eyelashes of the upper eyelid. Under the eyelashes of the lower lid is better to carry out a contour line with a pencil. Remove make-up better with wet wipes. And only after you remove the lens.
