New lenses - and reading glasses
Posted: Sun 20 Dec 2009 8:56 pm
My eyes have remained fairly stable for several years with no changes to my contact lenses, although over the last year or so I have found the need for reading glasses for small print and in poor light. The current reading glasses are a cheap supermarket pair and I had promised myself a designer pair for Christmas.
I had my check-up in April and as my lenses were a few years old and were suffering from protein deposits a new pair were prescribed. I've since been back to the hospital a few times and last month the edge lift of the lenses was changed with the hope that this will alter the way the eye lids rub the lenses and reduce the protein deposits.
The new lenses arrived and there were a couple of surprising effects. The left lens is such that I can read nothing at reading distance with my current -1.25 reading glasses - but at a distance the reading glasses don't blurr the vision. The right lens has improved my close vision, the reading glasses are almost redundant but distance vision is poor. Hence the pair had the unexpected advantage of not needing to play 'Hunt the reading glasses' whenever I wanted to read small print. Or to put it another way the left lens is too strong and the right lens too weak.
My next appointment was planned for May so I have had that brought forward to February and both new lenses have been returned to their little plastic pots as the vision is not as good as the previous pair.
Does anyone know why a small tweak to a lens can have such a noticeable vision change? I always dread the 'new lens' situation as even though my eyes are fairly stable it always takes a year to sort out.
Meanwhile the designer pair of reading glasses has been put on hold. Assuming that I get the lenses sorted in February I would like some advice - should I go for simple reading glasses or a varifocal pair so when I'm switching between close and distance work I don't have to hunt for my reading glasses?
