Presbyopia is an age related condition that effects your ability to focus clearly on near objects like printed text, computer screens and photographs. It primarily affects people over the age of 40 and is not a disease.
When light from a close object enters the eye it naturally comes to focus behind the retina. To focus the light properly the cilliary muscle around your lens contracts, which changes the shape of the lens, allowing the light to focus properly. With Presbyopia, your lens begins to gradually harden as you get older. This hardening of the lens does not allow it to change shape properly resulting in blurred vision.
There are a variety of ways to correct presbyopia including glasses, bifocals, trifocals or contact lenses. LASIK surgery or conductive keratoplasty, known as CK, are also options. Because Presbyopia is a gradual process you will need to consult your eyecare provider regularly to monitor the condition
