Despite being four-eyed since my teens, I am no authority on optical science. I would simpy say that as we age, our eye muscles lose their ability to adjust our focus, some worse than others. I believe my myopia has reach its maximum level of inefficiency (no degree change in the last fifteen or so years), but near level focus (between reading at book distance to computer screen distance) seem to change. Don`t know what is happening. Grew out of contact lenses years ago and not trusting of lasik, stick with spectacles. Just live with it I guess.
Cheers!
As you get older, your near sight fails you and very soon from +1.0, you become +1.5, +2.0, even +3.0 within a very short time. And when you get cataract ops done on one eye, the situation gets a bit complicated. You can correct for long distance with a new lens but it creates an in-balance with the "good" eye. If you can, wear a contact lens over the non-operated eye to correct the in-balance for far vision. As the contact lens sits directly on the eye, albeit with a layer of tears in between, it is the closest thing to the IOL that is inside the operated eye.
For near vision and indoor, wear a pair of progressive glasses. I disagree with LeongSam that the make does not matter. It does matter as far as how the positive diopter is done on the lens. Ideally this positive diopter geometry should be applied on the bottom and around the centre portion only and not at the sides. Epilsor lens is supposed to be able to do that, I am not too sure about the rest.
But I do agree that the fitting is even more important to get a troublesome pair of progressive glasses. The glasses should have sufficient vertical dimension to allow progressive accommodation to work properly. So avoid those thin, horizontal frames. Where the progressive geometry starts is also important. If it starts too high up and you watch TV and watch birds a lot, you do not want to droop you head doing it, very tiring for your head. If most of the time you are using it for close vision activities, by all means set it a bit higher.
Progressive glasses are particular needed for cataract operated eyes because of the limited focal range of the artificial lens. In a daytime active mode, I will use this combination, contact lenses with glasses for near sight. For more relaxed vision, say at night and you want to rest your contacts wearing eyes, you might go for fully powered progressive glasses but if you have high myopia and have done cataract operation on only one eye, I suggest you use it only indoor because of the vision imbalance.
