At around 45 to 50 Presbyopia sets in. The eyes lose ability to close focus when the muscles have not got their former strength. This is not unusual. If you have bright illumination the pupils get smaller and you get visual acuity from the 'pinhole camera' effect. Certainly see an optician and make sure there are no cataracts or any other sinister cause, but if you didn't need glasses before you will need reading glasses, which you can buy in supermarkets, +2 dioptres would be a useful strength.
I wear glasses to correct long sight and astigmatism. I have given up with varifocals and have distance glasses, and a +2 pair for computer use. For close work I have some bifocal specs with +2 in the upper portion and +3 in the lower segment.
For many years I had all my vision requirements looked after by an optician, for whom I had taken on a daunting task. He never forgot me for this and his gratitude was with me for the rest of his life.
What did I do ?
I MARRIED HIS BLOODY DAUGHTER !
