With normal eyesight, the cornea and the lens focus light directly onto the retina and the image you see is clear. Any change from this normal focusing is called a refractive error.
When the crystalline lens ages, some conditions named as Progressive Lens Dysfunction (PLD) can occur. PLD involves a wide range of symptoms and conditions that progress with age but there are various treatment options.
See below for more on the common types of vision problems that can typically be corrected through some type of corrective lens, such as glasses or contact lenses, to focus the light properly. Find out how LASIK MD can help you correct these refractive errors through our full range of procedures.
