Monovision an alternative solution to Presbyopia

Monovision is a technique used to deal with presbyopia; when the eye gradually loses the ability to change focus from far to close up - usually a result of aging. The idea behind monovision is for the presbyopic patient to use one eye for viewing distances and the other eye for viewing close up. Since one eye is corrected for viewing far and the other eye is corrected for viewing close up, the two eyes no longer work in unison. The results are poor vision quality and decreased depth perception. Monovision is most noticeable in low light and tasks that require sharp vision. In most cases, you will need to wear glasses or contact lenses to fully correct both eyes for viewing far distances or close up when performing tasks that require a sharp eye, such as driving at night, operating machinery, or performing tasks that require sharp vision.

Most patients have a hard time with having one eye blurred at all times. If you are considering monovision with LASIK, it is highly recommended that you go through a trial period with contact lenses to see if monovision can be tolerated. Different states also have specific requirements for driving with monovision.

Another thing to consider is how much your presbyopia is expected to increase over time. Your doctor should be able to tell you when you can expect your monovision surgery to no longer be enough for you to see near-by objects effectively without the aid of glasses or contacts, or when a second surgery might be required to further correct your near vision.
