When a person gets into their 40’s, the natural lens of the eye loses its ability to provide clear near vision. This is called presbyopia. Presbyopia is a normal part of the aging process and happens to everybody eventually. Symptoms of presbyopia include difficulty with close work including having to hold reading material farther away to see it, fatigue, and eye strain while reading.


Monovision is one of the ways Dr. Conlon can correct presbyopia and reduce a person’s dependency on reading glasses for near-vision tasks like reading a book or working on a computer. Monovision or blended vision is a procedure which focuses one eye for near sight, and the other for far-sighted vision.


Using the patient’s dominant eye, our doctors will correct your dominant eye for distanced vision. Your less-dominant eye will be intentionally left to a more nearsighted view, while still allowing your eyes to work together. This will improve your eye’s existing vision, clearing your eyes for both near and farsighted vision. While this may sound difficult to adjust to, many patients find it easy adapting to their new vision.


Dr. Conlon will fully correct one eye for distance vision and the other eye for near vision. If monovision is being considered, a trial with contact lenses will be extremely helpful. The monovision trial provides an idea of what it looks like to see the world with one eye set for distance and the other set for near. The vast majority of the time, individuals will quickly know if monovision is a good option.


Monovision can be achieved with laser refractive surgery (LASIK or PRK) or with the intraocular lenses used in refractive lens exchange and cataract surgery. If you are over 40 years old and considering refractive surgery, your consultation with Dr. Conlon will determine which presbyopia-correcting option is the best treatment for your specific condition and vision needs.
