Dysfunctional Lens Syndrome (DLS) is the term for the natural aging process of the eyes. DLS typically starts with presbyopia (the need for reading glasses) and then progresses into the development of cataracts. As you age, the chemical makeup of your lens can change, making your eye lens progressively cloudy and thick. This is the development of cataracts. It is typically the second stage of DLS and it is part of the normal aging process. As the cataract grows in size and opacity your vision will become distorted. This change to your eyes’ crystalline lenses can occur even if you have had excellent vision your entire life. Luckily, today there are many options for vision improvement.
