It is advisable your work space has computers set up at eye level to minimize visual fatigue. To be able to work at this range with little fatigue may require an especially designed lens power in your spectacles. There are few novelty products which are designed for office work which allow your eyes to focus with little fatigue. Discuss this at your consultation.
Consider evenly illuminated work environment with the light source not reflecting directly off the computer screen, as to introduce glaring or reflected sheen.
If time allows having few minute breaks every 20-30min is advisable. This may not only help with concentration and information acquisition but accommodative fatigue. Frequent blinking also helps the eyes stay well moistened.
Safety spectacles have saved a lot of eyes from injury, so do consider them. You can have safety lenses made to almost any prescription you need.
Do discuss these with our staff.
