How to prevent tired eyesight

This condition consists in the hardening of the eye muscles . The eye activates these, to focus closely, which modify the thickness of the lens, a transparent lens located behind the pupil, whose function is to focus the light rays to form a good image in the retina.

With the passage of time, these muscles lose strength and become less powerful, causing the lens to lose its flexibility.

Advances and a little more

The first symptoms of presbyopia They are well known: see badly up close, need plenty of light and feel tired when you read at the end of the day. It is a physiological process that reaches its maximum level at 65 years and affects approximately one thousand 800 million people in the world.

While the presbyopia it can not be prevented or mitigated by the consumption of certain vitamins or through visual training, the good news is that it is easy to detect and correct, either with glasses, contact lenses or surgery, using lasers or lenses implanted inside the eye.

What is monovision?

In Mexico, there are numerous solutions to correct the problem of "tired eyesight". One of them is the surgical procedure called monovision , which uses a laser or radiofrequency treatment that emits heat waves. These techniques allow modifying the shape of the cornea (transparent part with a vault shape that protects the eyeball), especially the eye that is not dominant (almost always the left), in order to adjust its focusing ability.

Thus, in a short time it is possible to significantly improve the sharpness with which objects are observed. Another option is progressive intraocular lenses. The possibility that this type of lens works is very high.

However, it is necessary to inform the patient both about the characteristics of the surgical intervention and the results of the same. Expectations are always high and, sometimes, it is not possible to recover a perfect focus ability or decreases night vision.

On the other hand, there are bifocal lenses that allow to see far from the top and from near by the bottom, without more than the natural inclination of the head. Habituarse to them is relatively easy, and only requires special attention in the first days of use, when going up and down stairs.

One drawback is that they do not allow a clear view at intermediate distances, which forces the person to approach or adopt uncomfortable positions. Another solution are the multifocal lenses , that allow a clear vision at any distance, simply by varying the inclination of the head, without needing to approach the object. It is a good alternative for those who require a broad visual field.
