Low vision is vision loss that’s so severe, it can’t be corrected with regular eyeglasses, contact lenses or surgery. Low vision and vision loss could be defined as best corrected vision which is insufficient to do what you want to do.
There are two parts to the definition:
- The Vision: best corrected with conventional spectacles or contact lenses.
- The Task: activities that you want to do but are now difficult or impossible. For example, activities include reading, writing, driving, television, playing cards, or seeing medication bottles.
For a person to benefit from Low Vision Care there must be a degree of usable vision and a goal to do a visual task. Dr. Bissell is trained by the International Academy of Low Vision Specialists (IALVS) and will discuss these issues in a free telephone interview before an appointment is offered.
Most conditions that cause irreversible vision loss do not cause complete and total blindness. Usually a person is left with “residual” vision that can be useful, especially with the help of low vision doctors. Low vision doctors of IALVS are uniquely trained and experienced in providing low vision glasses and devices plus rehabilitation training to make the most of the vision that remains.
Vision loss can occur from medical conditions, degenerative changes, congenital or genetic defects, and traumatic injuries. While most vision loss occurs in people over 65, low vision can occur at any age. Some of the major causes of vision loss are age related macular degeneration, diabetic retinopathy, inoperable cataracts, and open angle glaucoma.
