Black lenses for the whole eye

To create in the cinematograph various frightening images of demons, witches, vampires and other evil sprites, makeup artists often use black lenses for the whole eye. They are attached not to the pupil, but to the sclera, therefore they are called scleral lenses. Such adaptations are increasingly becoming a necessary accessory in professional photo shoots, clip art, themed parties, Halloween celebrations and masquerades.

What are black contact lenses for the whole eye?

Like the standard, scleral lenses look like a convex circle with a hole in the middle (for the pupil). In addition to the fact that they are large in size, from 22 to 24 mm, these contact lenses have an increased convexity index. This is due to the fact that after putting on the device the cavity between the lens and the surface of the sclera is filled with a special liquid, similar in composition to the lacrimal film.

The described structure is due to the original purpose of scleral lenses. They were invented for the treatment of ophthalmic pathologies:

• chemical eye burn;
• keratoconus;
• microphthalmia;
• strabismus ;
• aniridium;
• transparent degeneration of the eye;
• corneal defects;
• severe stages of the "dry eye" syndrome ;
• presence of scars after surgical operations.

Such lenses reliably protect sclera from external influences, since they are made of stronger materials than corneal ones. At the same time, these devices are very elastic and do not damage the surface of the eyeball. Lenses have high optical characteristics, and also have a multitude of microscopic through holes, through which the necessary oxygen, moisture enters the eye.

Previously, the considered accessories were selected very carefully or made to order, according to individual sclera measurements. Today you can buy black or color scleral lenses for eyes of standard sizes as an additional detail for creating the necessary images. However, their use requires compliance with certain rules.
