Nearly everyone over the age of 65 will experience a reduced elasticity of the lenses of their eyes — a condition called presbyopia.
Those of us lucky enough to have perfect vision until that age will only require reading glasses to help with up-close vision. However, for the 42 percent of Americans who are nearsighted, to begin with, a more complex solution will be necessary, such as bifocals, trifocals, or progressive lenses.
Bifocals: Pros And Cons
Bifocals are just what they sound like: glasses with one area that corrects nearsightedness and another area that corrects farsightedness. The worse presbyopia gets, it can start to affect middle distances too, and trifocals help by adding a middle strip for things like reading a computer screen.
If you’ve ever worn bifocals or trifocals, you know all about the line between the sections of the lenses. These lines can be distracting and create an odd “image jump” effect, and they can also serve as evidence of advancing age to anyone who sees them. Anyone who feels these drawbacks are too great to overlook might be more interested in progressive lenses.
The Science Of Progressive Lenses
Thanks to the wonders of modern technology, progressive lenses do what bifocals and trifocals do but without the distracting lines. The way this works is that the prescription gradually changes along a corridor of power, going from supporting distance vision at the top to close vision at the bottom.
The tradeoff to make such a complex lens work is that the bottom corners of progressive lenses make things appear blurry. Fortunately, newer technology is helping to minimize this flaw. When we examine patients wishing to buy progressive lenses, we measure pupillary distance so that we can place the corridor of power in the best place.
Getting Used To Progressive Lenses
Any time we change the prescription or frame shape of our glasses, it will take some time to get used to the way things look. This is certainly the case for progressive lenses, especially if it’s your first time wearing them. A few things you can do to adjust more quickly include:
moving your head instead of your eyes to see different things
making sure the glasses fit properly so that the corridor of power stays in the right place
practicing looking at objects at different differences by watching TV and reading a book at the same time
not giving up! If you switch back and forth between your progressive lenses and your old bifocals, you’ll reset the clock on your eyes getting used to them!
