LOW VISION Meaning and
Definition
-
Low Vision refers to a visual impairment where an individual experiences significant difficulty in seeing clearly, even with the use of corrective measures such as glasses or contact lenses. This condition typically occurs due to eye diseases or conditions and is characterized by reduced visual acuity or a limited field of vision. People with low vision may have difficulty distinguishing details, reading small print, or seeing objects in dimly lit environments.
Unlike complete blindness, individuals with low vision still retain some degree of visual function. However, their vision is severely impaired, impacting their ability to perform everyday tasks such as reading, writing, and recognizing faces. Low vision can be caused by various eye diseases such as macular degeneration, glaucoma, diabetic retinopathy, or cataracts.
To assist those with low vision, various optical aids and devices can be utilized. These aids include magnifying lenses, telescopes, special filters, and electronic devices designed to enlarge images. Additionally, low vision rehabilitation programs offer training and support to help individuals develop alternative techniques and strategies to maximize their remaining vision and regain independence.
Overall, low vision is a visual impairment that significantly hinders an individual's ability to see clearly, impacting their daily activities and quality of life. It necessitates specialized interventions and support to optimize the remaining vision and enhance independence.
