Special glasses for preventing and treating eye diseases

Russian scientists have designed and built special glasses to prevent and treat eye diseases in the elderly.

Until recently, visual impairment at an advanced age was considered inevitable and incurable.

The author of this invention, Mikhail Ostrovski, Academician of the Russian Academy of Sciences is currently working at the NMEmanuel Institute of Biochemical Physics, saying that the eyes of animals and humans are the most convenient tool to continue. Natural sunlight collection.

Many animals have yellow lenses in their eyes, capable of blocking ultraviolet rays and even blue-violet rays. These are the two most dangerous colors for the retina.

In humans, in adolescence, the lens is almost colorless, giving extremely short light in the visible spectrum (400-500 nanometers) and does not allow ultraviolet rays to enter the eye. Over time, the lens gradually fades and turns yellow (so when people are young they look at the blue sky).

As a natural reflex, in the retina the eye appears to have additional yellow filters. Therefore, yellow lens is the object of research by scientist Mikhail Ostrovski.

In this study, scientists learned about how light energy turns into a visual signal in the eye's visual cells. Next, the sight signal is transferred to the brain to synthesize information, and people see the world around them.

In other words, light is the unit that carries visual information. However, there is still the concept of 'visual paradox'.

The fact is that in risky situations, light can negatively affect the retina. So scientists have investigated the process of light rays that damage eye cells. The results of the study suggest that they have a relatively simple way of thinking.

As is known, in the case of patients with cataracts, surgical intervention is required to replace artificial lenses. The idea of ​​these scientists is to need surgery to implant a yellow lens rather than a colorless one. At that time, this artificial part will act as a color filter, not allowing dangerous rays to penetrate the retina.

According to Academician Mikhail Ostrovski, so far the Institute of Biochemical Physics called NMEmanuel has implanted nearly 1.3 million yellow artificial lenses. The result was a 10-fold decrease in the number of retinal burns and other complications.

He also said that the institute has developed a model of solar lenses in the form of yellow artificial lenses, capable of protecting the eyes of those who have pathological distortions in the eye mesh from the harmful effects of rays. blue purple.

New type glasses look like normal sunglasses. The only other thing is that it is made of a material that can block dangerous light rays to protect the retina from the negative effects of intense light.
