Glasses To Treat Visual Impairment

Third generation glasses can prevent and can treat visual impairment in many cases where there is still activity in the retina.

Visual impairment affects many people in our country. Spain follows the WHO classification of visual disorders. So, according to this organization, a person is considered legally blind when their visual acuity is 20/200 after applying all possible correction and in the best of eyes.

However, it is considered blind or blind when vision is less than 20/400 or when the visual field is less than 20 degrees. The normal thing is to have a visual acuity 20/20 and a visual field of 180 degrees.

This means that there are numerous cases of blindness in which there is still some activity in the retina and in which lights and shadows are still perceived. While in many of them visual acuity is below the limit of blindness.

According to the WHO, around the world there are about 285 million legally blind people. Of the total, 39 million are blind and 246 million have low or very low vision. And one fact to keep in mind is that  80% of the world’s total cases of visual impairment can be avoided or treated. This is because they are the cases to which the eSight 3 glasses are directed.

The third generation eSight glasses allow the visually impaired to :

• Watch.
• Move.
• Gain independence.

It is a device similar to the glasses used for virtual reality, but which  are designed to improve and even restore sight to people with very low or almost no vision. In this article we tell you more details about these glasses that improve the quality of life of people with visual disabilities.

How are glasses designed to treat visual impairment?

In appearance, eSight glasses are very similar to virtual reality glasses , but their operation varies.

The glasses consist of two frames, one inside in which the usual prescription lenses can be mounted. Above the internal glasses is the other frame that has two small OLED screens. Each one is in front of each eye, and it is in them where the image we want to see is shown.

The outer frame can be moved up with a slight movement in order to be able to wear inner glasses with the usual prescription. This allows the user not to have to change glasses to interact with their environment on a regular basis when it suits them.

In fact, they can be considered as small binoculars  that generate an image so powerful that the eye is able to decipher it. However, its operation is more complex than this.

There were already devices capable of achieving similar results, so the most cutting-edge technology has been integrated with the aim of facilitating the vision of everything that is around us and not just a specific point.

They are programmed with the patient’s data.  For this reason, the image that it receives is treated with an algorithm that provides an image appropriate to their characteristics. What is achieved is an individualized solution for each person.
