Laser in ophthalmology

Laser surgery (light amplification by stimulated emission of radiation) is destined to correct vision problems such as:

  • Nearsightedness : images are not produced on the retina but in front of it
  • Farsightedness : images focus behind the retina

Night vision

Before you can see something in the dark, it is preferable to let the eyes accommodate for half an hour without looking to light sources. It is also preferable to use peripheral vision and concentrate on contours, movements and any abnormal forms. Ideally, objects must be seen starting from the bottom to get a better view of their contours and use a scanning technique. Motorists are concerned by night vision. If most of the accidents occur during night time, it’s partly because of bad visibility, traffic is of course not the issue at night. Lighting of the road is spaced to avoid blinding the driver.

Exercises to improve vision


Exercises to improve vision exist since dozens of years and we can find traces in articles dating from 1920. Part of these exercises aren’t made to improve vision, but to take care of them make them less tired, which will indirectly improve vision. We all spend an awful lot of time in front of the computer screen or fixing something too close to our eyes, this habit tires the eyes a lot, it is therefore very important to take breaks every now and then to relax the eyes and avoid damaging them. Every 3 hours is a good period of time if you work in front of the computer, as an electrician or sewing. During this pause, fix a point that is far during a few seconds, go back to normal and try this a few times more. You can then close your eyes and make them move up and down during a minute. This way, the eyes will get tired less quickly and will take less damage from work, which will improve your vision if you suffer from eye strain.Read more…
