Low Vision 101: A Quick Guide
Understanding Low Vision
Low vision is a significant loss of sight that can't be corrected with glasses, contact lenses, or surgery. It doesn't include complete blindness, but it can still impact daily activities. Vision aids can help you manage this condition and improve your quality of life.
Types of Low Vision
There are different types of low vision, including loss of central vision, loss of peripheral vision, night blindness, blurred vision, and hazy vision. Each type affects your sight differently and requires different coping strategies.
Causes of Low Vision
Low vision can result from various conditions and injuries. Age is also a factor. Common causes include macular degeneration, glaucoma, cataracts, optic neuropathy, diabetes, and eye trauma, among others.
Diagnosing Low Vision
Low vision is diagnosed during a comprehensive eye exam, including tests for visual acuity, depth perception, and visual fields. Early diagnosis can help you better manage your condition.
Treatment Options
While some sight disorders can be treated to restore vision, low vision is often permanent. However, visual aids like magnifying glasses, telescopic glasses, and reading prisms can help you see better and continue your daily activities.
Visual Aids and Devices
Many visual aids are available, including handheld and freestanding magnifiers, lenses that filter light, closed-circuit televisions, and smartphone apps designed for people with low vision.
Non-Optical Aids
Non-optical aids can also help people with low vision. Popular devices include text-reading software, check-writing guides, high-contrast clocks and watches, and large-print publications.
Preventing Low Vision
Some conditions that cause low vision, such as diabetic retinopathy, can be prevented. Regular eye exams and managing underlying health conditions can help prevent or delay the onset of low vision.
Low Vision Rehabilitation
Low vision rehab can teach you new skills and ways to adapt. This includes orientation and mobility training, making home adjustments, and technology training.
Improving Quality of Life
Visual aids and rehabilitation can improve your quality of life if you have low vision. By making the most of your remaining eyesight and helping you adapt to changes, you can stay active, social, and independent.
