Vision Over 40

No more glasses! Learn about our Monovision procedure!

If you find yourself holding the paper or your phone at arm’s length to read small type, we have the solution!

In monovision, one eye, usually the dominant one, is focused at distance. The non-dominant eye is focused at near. With both eyes open, the brain automatically picks the image that is best in focus. Our monovision procedure helps eliminate the need for bifocals or reading glasses!

Presbyopia – Reading Vision Loss

Recently, you’ve noticed reading vision is slightly out of focus. There is no need to be concerned. Near vision loses some of its crispness once we’re in our 40s as the eye becomes more rigid, loses it’s flexibility. The technical term for this is presbyopia. Watch videos about presbyopia here.

Presbyopia is a natural process that happens to everyone – even after laser vision correction. It can’t be avoided or prevented, but it can be successfully treated.

How does presbyopia affect your eye?

The lens in your eye is stretchy and flexible. To create a sharp image, light rays pass through the lens in a cone shape that converges at a single point on the retina. This point at the tip of the cone is called the focal point. Little muscles surrounding the lens continually bend its shape so you can focus on objects near, far and in-between. With time, lens material stiffens. It can’t bend into the right shapes to make the focal point land on the retina and bring close objects into focus. To compensate, you end up moving objects just the right distance to focus. This is why you start holding reading materials at arm’s length.

When the lens becomes less flexible, the focal point converges behind the retina. The light rays that actually strike the surface of the retina are at a broader point in the cone. They are not concentrated into a single point, so things look blurry. This is presbyopia.
