Visual impairment, also known as vision impairment, is a condition that affects the ability to see. It can range from mild to severe, and can be caused by a variety of factors, including genetics, disease, and injury. People with visual impairments may have difficulty seeing objects clearly, distinguishing colors, or navigating their surroundings.
Understanding Visual Impairment
There are two main types of visual impairment: low vision and blindness. Low vision is defined as having a visual acuity of 20/70 or worse in the better-seeing eye after correction. Blindness is defined as having a visual acuity of 20/200 or worse in the better-seeing eye after correction, or having a visual field of less than 20 degrees.
Visual impairment can have a significant impact on a person's life. It can affect their ability to learn, work, and socialize. However, there are many resources available to help people with visual impairments live full and active lives.
Causes of Visual Impairment
There are many different causes of visual impairment, including:
- Genetic conditions, such as retinitis pigmentosa and macular degeneration
- Diseases, such as glaucoma and diabetic retinopathy
- Injuries, such as those caused by accidents or sports
- Age-related changes, such as cataracts and presbyopia
Some causes of visual impairment can be prevented or treated, while others cannot. It is important to see an eye doctor regularly to get your eyes checked for any signs of visual impairment.

- Blurred vision
