How bad do your eyes have to be to not be able to get laser eye surgery

Distribution of personal computers, plasma panels of TVs and monitors force ophthalmologists to reflect on preventive maintenance and removal of a computer visual not be able to get laser eye surgery syndrome (Computer Vision Syndrome) which is often combined with a syndrome of "a dry eye».

The sight of the person generated during long evolution, in the XX-th century has appeared is a little adapted for work with the computer image. The screen picture bad eyes have differs from natural that it self-shone, instead of reflected. Visual loading essentially increases because of necessity of constant moving of a look from the monitor screen on the keyboard and the paper text. Frequently the workplace is correct and rational to organise impossibility (patches of light on the screen of the monitor from external sources, wrong distance from eyes to the screen, the unsuccessful choice of colours, excessively big brightness of the screen) aggravate a situation.

The greatest general exhaustion is caused by work in a dialogue mode. Special loading on sight is represented by the computer drawing - performance and a correcting of working drawings by means of the not be able to get laser eye surgery personal computer.

The problem consists in the following: many of us spend till 8 o'clock a day in front of the computer, on work, houses or in game club. Even you now read this material, looking at the monitor.

In risk group «computer syndrome» - active users of personal computers at the age from 18 till 40 years. Complaints of the people spending the most part of bad eyes have working hours behind the screen of the monitor, it is possible to divide on two groups:

- The optical


Visual acuity decrease;

The slowed down refocusing from near subjects on distant and back (accommodation infringement);

Doubling of subjects;

Fast exhaustion at reading.

- The physical


Burning in eyes;

Feeling of "sand" under centuries;

Pains in the field of eye-sockets and a bad eyes have forehead;

Pains at movement of eyes;

Reddening of eyeballs.

Research of visual functions at people, within several years of personal computers working behind screens, has revealed decrease in volume of accommodation in comparison with age norm and the big frequency of short-sightedness in comparison with people of the same age, not connected with the computer. At the persons showing the above described complaints, all these changes have been not be able to get laser eye surgery expressed more sharply. Research of influence of the work with the display on sight has shown, that for a labour shift there is a reduction of volume of accommodation, and at some users develops time (so-called false) short-sightedness.

In a modern life without the computer not to manage any more. But how from «inevitable harm» to transform it into really useful assistant?


Do not neglect visiting of the ophthalmologist, and be not engaged in self-treatment.

Use special drops for the eyes, replacing tear

Limit an operating time behind the computer no more than 4 hours per day

Do obligatory pauses in an operating time at a short distance every 20-30 minutes

The correct organisation of a workplace and rational operating mode has great value.

Especially important observance corrected for children and teenagers when refraction formation has not developed yet and excessive loading can lead to short-sightedness development. Children are recommended to spend time at the personal computer only with the informative purpose

Get special points with progressive lenses in which the zone of clear vision corresponds to look moving at work on various distances. Application of such points for intensive users of the personal computer has given decrease in visual exhaustion and improvement of indicators of accommodation in comparison with usual points at 85 % of workers.

At observance of the listed recommendations the quantity of the errors made by the operator, especially in second half of day decreases, irritability and headaches leave, the emotional condition improves. In points with the computer filter comfortably in a premise shined with artificial light sources, (especially luminescent lamps) since points improve spectral structure of light getting to eyes. In them it is comfortable in the street, in cloudy weather - it is visible more accurately and more contrastly, and in a sunny not be able to get laser eye surgery day they do not pass very active short-wave part of a spectrum in eyes. Thus, points with the computer filter can be recommended for constant carrying. And it is very important, for more than 50 % of programmers - people in points.

ALL RECOMMENDATIONS SET FORTH ABOVE SHOULD BE DISCUSSED WITH THE OPHTHALMOLOGIST!

Dryness of eyes rather widespread problem among users the computer. Consider, that the reasons of a wide circulation of dryness of eyes among users of the computer a little:


More rare blinking of the user at work on the computer (frequency of blinking makes about third of usual frequency);

Widely opened eyes at image examining on the monitor, it leads to increase in speed of evaporation of tear from an eye surface.

For syndrome reduction «a dry eye» at work on the computer it is necessary to provide correct working conditions, first of all:


Correctly to establish the monitor screen (the centre see on 10-20 below eyes of the user)

To choose correctly distance (not less than 50 see) to the monitor

Besides, users of the computer should be reminded of necessity more often to blink at first signs of dryness of eyes

It is necessary as from time to time to close eyes and to make some get laser eye surgery circular (rotary) movements

It is useful to arrange 2 - 3 minute breaks at work on the computer, focusing a sight at a long distance.
