As we age, the lens inside the eye becomes rigid and less flexible, and loses its ability to focus on a close object. This condition is called presbyopia. If someone has good distance vision, or wears glasses to correct their distance vision, their close vision will become blurry, and they will need to hold their reading material further away. There are many options to correct for presbyopia. Some patients may just wear reading glasses. Others may need bifocal lenses or progressive "no-line bifocals". We also have the option of correcting it with contact lenses. Monovision is one option, where a patient will wear one contact lens in one eye for distance vision, and the other eye will have a reading lens, and the brain adapts to using one eye at at time. If monovision does not work well, multifocal contacts may be an option. Multifocal lenses have both distance and near prescriptions within the same lens and are worn in both eyes, giving you "simultaneous vision". Talk to one of our doctors to see which option is best for you.
As we age, we will also develop cataracts, which is a clouding of the lens in the eye causing blurred vision. Traditionally, after cataract surgery, patients have required reading glasses. We now have the option of implanting multifocal intraocular lenses to correct both distance and near vision so that the patient may not require reading glasses. Monovision is also an option with cataract surgery, especially if the patient wore contact lenses this way before their cataracts became a problem.
