Dysfunctional Lens Syndrome

Dysfunctional Lens Syndrome (DLS), also known as presbyopia, is the term used to describe the age-related deterioration of reading (or near) vision. This condition that affects millions of Americans causes an inability for our eyes to focus properly when reading things up-close. It is commonly called “Over-40 vision” because it tends to affect patients that are aged 40 years and older.

Causes of DLS

DLS cannot be prevented because it is a natural part of the aging process. Around age 40, our eyes’ lenses begin to harden and become less flexible, making the lens unable to function the way it once did — hence the term ‘dysfunctional lens’.

Dealing with DLS

DLS has traditionally been managed with simple, over-the-counter reading glasses. However, this means constantly purchasing stronger and stronger magnifications as the condition worsens. Many people get frustrated at having to search for glasses in order to read their computer screens or newspapers. In some cases, eye doctors may suggest bifocals, which may take some initial adjustment time.
