People who often like to change their image, and pay attention to even the smallest details in the image, often get colored contact lenses. These small accessories allow you to emphasize or radically change the natural shade of the iris, to give it an extravagant and unusual look due to a variety of patterns. In addition, these devices can additionally be used for vision correction .
How are contact lenses made?
To find the perfect accessories, it is important to carefully study their main characteristics.
First you need to determine the material of manufacture. There are two large groups of described devices - hard and soft colored contact lenses. More than 90% of the used drugs are of the latter type, they are made from hydrogel or silicone hydrogel . Rigid accessories are made from special polymers, they are recommended only for correcting severe variants of astigmatism and keratoconus.
The next stage of lens selection involves choosing their color and saturation. There are several varieties described by the devices:
- toning, translucent;
- overlapping the natural tone of the iris;
- "Crazy" or carnival.
The first specified type of accessories is more suitable for light eyes. It allows you to make the natural shade of the iris deeper and more saturated, but do not change it radically.
For dark-colored eyes, color contact lenses with an opaque layer of pigment are recommended. They provide a change of any shade of the iris to the desired tone.
Carnival devices are usually used in creating images on a photo shoot, themed parties, costumed celebrations. Accessories like "crazy" are distinguished by a huge variety of shocking patterns and unnatural shades. With their help, you can even change the color of the sclera.
Another important characteristic in the choice of contact lenses is the frequency of their change. There are several recommended periods for wearing them:
- day;
- 1-2 weeks;
- month;
- up to six months;
- 12 months (traditional).
It is worth noting that even the best color corrective contact lenses are not recommended to be used constantly and regularly. Ophthalmologists are advised to wear them not more often 3-4 times a week for several hours, preferably in the daytime. The fact is that in the evening and with insufficient volume of light the pupil expands, accordingly, the colored part of the accessory gets into the field of vision, which is perceived by the brain as visual disturbances.
Colored contact lenses with diopters
Usually, the corrective devices are produced in a shade form, since their translucent structure allows to see clearly regardless of the degree of enlargement or narrowing of the pupil and without interference.
Other varieties of colored lenses with diopters are less common, although they are also quite in demand. Specialists do not recommend the use of overlapping iris and carnival accessories of such a plan often and for a long time. The allowed wearing time is 2-4 hours, 1-2 times in
Color contact lenses without diopters for eyes
If there are no problems with vision, there are no special restrictions on the duration of the use of carnival, color or pupil diameter-enlarging lenses.
The main thing is to buy quality accessories with sufficient gas permeability and high water content (about 70%). This provides free access of oxygen to the cornea of the eye, as well as moisturizing the surface of the eyeball, which prevents irritation and pain during prolonged wearing of contact lenses.
