How to change eye color without lenses

What it is

Lenses can be a means of vision correction. In some cases, their use is associated with aesthetic purposes. Contact lenses can be not only colored, but also with a variety of designs.

Attention! This article is for informational purposes only. To select crazy lenses, you need to contact an ophthalmologist.

Crazy lenses:

• have characteristics - radius of curvature, optical power, etc. (like regular contact lenses);
• completely change the color of the iris;
• require standard care;
• have a certain wearing period - usually from 30 to 90 days;
• can only be worn during the daytime (wakeful period) for no more than 6 hours;
• It is prohibited to purchase without consulting a specialist.

It must be remembered that crazy lenses (regardless of their optical power or lack thereof) must be properly stored and treated with a disinfectant solution. There are standard contraindications for wearing them: inflammatory and infectious eye diseases, insufficient corneal moisture, etc.

What causes eye color

The color of the eyes is determined by the characteristics of the iris. The iris has a complex layered structure and different localization densities of pigment cells in the layers. Its shade depends on the amount of melanin and the surface pattern, which is created by radially and circularly located vessels and connective tissue fibers. The pattern on the iris is as unique as fingerprints.

The iris consists of 5 layers, but the highest pigment content is observed:

• In the outer boundary layer, consisting of fibroblasts, fibers and pigmentocytes. The structure of this layer determines the color of the eyes.
• In the posterior pigment epithelium, which has an almost black color due to the content of a huge amount of melanin, regardless of the shade of the eyes. Thanks to this layer, the iris is lightproof; rays pass only through the pupil.

The main pigment of the iris is melanin. It gives fabrics a black-brown tone. There is no blue or green pigment in the iris.

These colors are formed due to the following factors:

• different melanin content in the anterior boundary layer,
• different density of connective tissue fibers,
• the ability of light rays to be reflected and absorbed by the layers of the iris.

With high looseness of fibers and a small amount of pigment, part of the spectrum of light rays is scattered, and rays with a wavelength of a certain range are reflected, which results in blue or light blue eye color. With a dense stroma of the iris and a high concentration of melanin, a significant part of the rays is absorbed, resulting in a brown color. Only 2% of people in the iris, in addition to melanin, contain the yellow pigment lipofuscin, which overlaps the blue spectrum and gives the eyes a green color.

Eye color may change with age. Most newborns have blue eyes, which is due to low pigment content. In older people, the eyes become lighter due to degenerative processes in the iris. Also, the cause of color changes can be various ophthalmological diseases, metabolic disorders and pathologies of other organs.

If the shade of the eyes has changed over a short period due to unexplained reasons, spots of a different color or various inclusions have appeared on the surface of the iris, then you should consult a doctor.

How to choose

Decorative “crazy” lenses have a number of characteristics. When choosing them, you need to focus on various indicators, the manufacturer and other factors.

Without diopters

In order to decide which lenses to choose, you need to pay attention to:

• their moisture content (the higher it is, the better);
• material of manufacture;
• manufacturer (it is better to purchase a trusted brand);
• wearing period;
• the number of lenses in the package (some brands are allowed to buy 1 piece, which makes it possible to make the image even more interesting);
• ophthalmologist's recommendations.

Your own preferences are important. The choice of crazy lenses is based on what style and image is needed at the moment.

There is a separate category - scleral lenses. They cover the entire eye completely, which helps achieve the desired effect.

Scleral crazy lenses are more difficult to put on and take off. They require more hydration and care must be carried out more carefully.

With diopters

To choose “crazy” lenses for poor vision, it is not enough to focus only on the above factors. It is also necessary:

• obtain a prescription indicating the required diopters for each eye;
• have lenses with the expected optical power tested by an ophthalmologist;
• evaluate wearing comfort;
• make sure there are no headaches or deterioration in visual function.

It is forbidden to wear contact lenses that have already been used. This may cause eye infection. If changes in refraction are present, such actions entail consequences in the form of visual impairment.

Medical cosmetic lenses

Various types of contact lens coloring are used to mask eye defects (medical cosmetics), change the color of the iris (decorative colored lenses) or enhance the shade of your own eyes (decorative tint lenses). Colored lenses with decorative patterns (cat's eye, dollar, etc.) are also produced, which are used for entertainment.

In this article we will talk about cosmetic lenses for which there are medical indications. Often these lenses are also called camouflage or camouflage .

These lenses are created on the basis of standard hydrogel or silicone hydrogel contact lenses by coloring them at the factory or in a special laboratory. The lenses you will use can be either standard colors or custom-colored for you. The optical power of lenses can be zero, plus or minus refraction.

These cosmetic lenses are suitable for both light and dark eyes.

Below is a list of pathologies for which wearing such lenses is indicated:

. They help cope with the so-called cataract (clouding) - a defect that occurs after injuries or inflammatory diseases of the cornea. A lens that imitates a black pupil hides this defect.

. They cope with the manifestations of diseases associated with deformation of the structure of the iris: such as colobomas, ruptures of traumatic or congenital origin. Also, disorders of pigmentation of the iris: with these pathologies, part of the iris is missing or the color of one of the sectors of the iris is changed. A special lens with a painted iris not only “masks”, but also improves the quality of vision .

· Used for eye intolerance to sunlight. Such lenses protect the eyes from harmful radiation much more reliably than glasses with tinted lenses.

· Colored lenses are used for amblyopia (“lazy eye”) to provide visual stress to the affected eye. It is much more convenient to “close” the eye with a lens that prevents the entry of light than to seal the glass on the glasses.

These lenses have a number of features. Due to the presence of dye, the oxygen permeability of such lenses is less than that of colorless lenses. Therefore, you need to wear cosmetic lenses in a gentle manner.

When using intensely colored lenses, it should be remembered that the diameter of the pupil in some cases may exceed the diameter of the central uncolored zone of the lens. This may cause the image to be somewhat blurry in some areas of the field of view. This effect is more often observed in low light conditions, for example when watching a movie in a cinema or when driving a vehicle at night.

We work with all leading manufacturers of cosmetic lenses : Svetlenz, Concor, Alcon, Adria, NeoCosmo, OcularSinces. Thanks to this, we can produce finished lenses faster than other optics.

Feedback from patients suggests that thanks to the wide range of modern manufacturers, everyone can choose lenses to suit their taste. The only drawback of crazy is that it dries out the tear membrane.

• Svetlana, 20 years old, Irkutsk: “I use crazy lenses from various manufacturers in theatrical productions. If you wear them for a short time - 2-3 hours, then everything is fine. For longer use, you need to carry moisturizing drops with you.”
• Roman, 31 years old, Samara: “I recently tried Adria Crazy scleral ones. At first it was unusual - difficult to put on and take off. Then I got used to it. Sometimes there is a feeling of a foreign body in the eye, so I try not to wear it for a long time.”
• Margarita, 27 years old, Voronezh: “I have been using contact lenses for vision correction for quite a long time. I tried the carnival ones. The effect pleasantly surprised me - everything is visible well, the drawing is bright. I hardly noticed any difference. The only negative is the rather high price of crazy lenses with diopters.”
