Why does eyesight drop?

Few people think about the question: "How to save eyesight?" until the moment when it begins to visibly deteriorate. But in the overwhelming majority of cases that led to visual impairment, this could have been avoided. Where is the sight lost?

The age of rapid development of new technologies has led to the fact that reading in transport has become commonplace (or rather, an integral part of the travel process). The habit of reading small print from electronic mobile media on the road has become the source of several problems:

the optical system of the eye is in constant restructuring, trying to focus on the text that trembles at the moment of movement of transport - this eventually reduces the functionality of the optical apparatus of the eye;
the small print of mobile phones strains the eyes, and few people use the possibilities of adjusting the font sizes;
the poorly lit interior of the vehicle tires the eyes.

Working with monitors and watching TV often contributes to a decrease in visual efficiency. And if you watch a movie from a small telephone monitor, then consider that in the near future you are the owner of a pair of glasses.

Reading in dim light will gradually reduce sharpness and quickly "sit" your eyes.

Eyesight drops especially quickly if you get involved in watching movies in 3D. Watching movies with 3D glasses inflicts the greatest damage on children whose optical apparatus is not yet fully formed.

Stressful situations also contribute to a drop in vision Changing blood pressure readings during stress will also affect the eye pressure, which in turn can lead to irreversible changes in the functional characteristics of the optical system of the eye.

Natural sunlight is most favorable for the eyes, but not when the sun's rays are burning mercilessly. This blinding light can damage the eyes not only in summer, but also in winter, when, on a bright sunny day, the rays are reflected from snow crystals and hit the retina of the eye, burning it.

Working with vapors of harmful chemicals leads to the fact that the particles of chemicals, in contact with the cornea of the eye, burn it.

The earliest signs of visual impairment can manifest itself in the form of rapid eye fatigue, increased tearing, or, on the contrary, a feeling of dryness, the eyes are covered with sand, dizziness, and headaches. These are the first hints that you need to take care of your vision, because vision is our main link with the outside world.
