I am now the owner of a pair of reading glasses to correct middle age presbyopia.
When I collected the glasses they gave me a 'test' card to read and I said that I could read the same with the glasses as I could without the glasses. The staff member suggested that with a weak prescription (+1.00) the difference in sight between glasses and no glasses will be fairly minor, but that wearing the glasses would make it less likely that my eyes get tired.
I've been experimenting at home, and I'm now wondering if the glasses actually make my vision worse. I was slouching over a recipe book in the kitchen today with my face closer to the table in order to see the words properly. Being more upright just made the page look blurry.
Do my eyes need some time to get used to the glasses and a different reading position? Maybe I've just got used to reading things at a distance. I've just tried reading a magazine and moving the page in and out from my face and the text does seem clearer but only when unnaturally close.
