At Laservision, we offer a wide range of solutions to reverse the effects of presbyopia and improve reading vision. Please click on the conditions below to learn more about these conditions and possible treatments.
The natural lens in the 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. These fine adjustments move the focal point – the tip of the cone, so it always lands exactly on the surface of the retina for a sharp image.
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.
