At the same time, research is underway in several European countries to create a new generation of contact lenses that will perform a number of functions in addition to conventional vision correction.
For myopic children who do not want to wear glasses, silicone contact lenses have been developed that are inserted only during sleep. Their action is based on the effect of orthokeratology - changing the shape of the eyes. Lenses put pressure on the cornea, thereby reducing its curvature and slowing the progressive myopia.
Research shows that these lenses are most effective from the age of 5 until the end of the child's vision. Professor of Optometry at Aston University (Birmingham) James Wolfson spoke about the effect of lenses:
“The lens has a rigid structure. At night, the eyelid presses on it and thus the cornea is massaged. From this, it becomes flatter and vision correction occurs. In the morning, the child sees much better, and this effect lasts for several days.
The lenses are designed for six months. They cost around £ 200. Another novelty is lenses with UV protection.
Meanwhile, Swiss scientists have created contact lenses that resemble built-in binoculars for patients with age-related macular degeneration (AMD). Lenses work in conjunction with smart glasses and can magnify 2, 8 times, for which you need to blink the right eye. Blinking with the left eye, the patient returns the lens to its original state.
