If a person lives in a restricted space for any length of time, such as those confined to bed for months following a serious accident or illness, is the eyesight affected?
I am thinking they won't have the opportunity to focus on far distance.

I chose the lens to be focussed on distance and now, without specs, I can comfortably drive the car and read both the instruments and the road ahead; I can also watch TV at a distance of about 2 metres. As far as the eye is concerned anything beyond a metre or so is infinity. Putting it the other way round the eye is normally focussed on distance and uses muscles to squash the lens to allow it to focus on closer objects.
Thanks, bhg. I'm glad your op is a success, must make a big difference to your life.
I know cataract removal is a relatively straightforward op and I believe the results are permanent, your eyesight won't deteriorate.
Why don't people opt for that instead of laser treatment when they prefer not to wear glasses?
Laser treatment serves a different purpose. If God(or your mum) supplies you with the wrong lens in your eye you are either long or short sighted and need to wear specs to correct. Laser treatment shaves bits off the lens to change its focal length so that you can see clearly without specs at all distances. The original lens remains in place and can still develop cataracts later in life. Cataract removal replaces the lens with the cataract with a clear plastic one and they take the chance to correct long/short sight and astigmatism whilst they are at it.
After a serious accident I was lying in the same position on a hospital bed for several weeks, pretty much in the same position looking at the ceiling. When I was finally able to move to the outside world focusing was not a problem, however adjusting to colour was another matter. Flowers, trees, fields etc. in full colour took quite a while to adjust to.
oh is that Fuchs diesease ? ( not enough layers of the cornea?)
I think the idea of the eye getting tired and myopic with disuse is based in the idea in the fifties that children werent squinty and short sighted - - they needed eye exercises ! ( lazy blighters, beat them!)
anyway, didnt work
No, Florence Nightingale who spent the last twenty y of her life on a day bed ( o god her secretaries went scribble scribble scribble) was short sighted for other reasons ( age) ( than looking at the wall)
