Computers and eyes
Many people are concerned about the increase in computer screen work and their ability to see. It is without doubt an exacting task for the eyes.
Will the computer weaken my eyes?
Many people will have slight inefficiencies within their visual system, but be unaware that their vision or focussing has a potential weakness.
It is not until that person becomes involved in a visually demanding task that these latent problems become manifest. The 2 classic tasks that do this are computers (VDU) and night driving.
The VDU thus doesn't cause the deterioration, but can make you more aware of any slight problems with your eyes. It is also important to remember that the focusing system weakens with age.
Will the computer cause permanent damage to my eyes?
There have been concerns of possible UV damage from the screen.
The scientific bodies state that there is no evidence of this.
Dry, gritty, sore eyes?
What generally happens is that when you are concentrating on the screen, you tend to blink less. This, in addition to being in a dry air-conditioned office or centrally heated room, can disrupt the tear film, resulting in the above symptoms.
How can I make computer work more comfortable?
Check the position of the screen.
Take regular breaks from the screen, this has 2 advantages:
It gives your focussing system a rest.
It reminds your brain that there are 'other' distances to focus at. This can help prevent your focussing system from 'fixing' at the mid-distance avoiding a consequent drop in far distance.
Blink to refresh your tears. Tear comfort (supplement) drops are available to ease any discomfort.
Have an eye examination to make sure your eyes are working efficiently. You may be able to see very clearly, and yet your visual system may be struggling. With VDU work it's not what you see but how you see.
Should my employer pay for the eye examination?
The European Directive states that if you use a VDU for 'most' of your job, then your employer should pay for a regular eye examination. If it is found that you need a prescription specifically for the screen, then they should contribute towards these spectacles. You should check your company's policy with personnel or health and safety.
Remember
when using the screen, it is not what you see, but how you see.
your employer may well pay for your eye examination.
