Vision loss, also known as visual impairment or blindness, refers to a significant reduction in vision that cannot be corrected with glasses, contact lenses, medication, or surgery. This condition can affect people of all ages and can have various causes, ranging from genetic conditions to age-related diseases.
Understanding Vision Loss Basics
Vision loss is a broad term encompassing any degree of visual impairment that affects daily activities. It ranges from mild vision problems to complete blindness. Understanding the basics of vision loss involves recognizing its impact on an individual's life and the various ways it can be managed.
Causes of Vision Impairment Explained
Vision loss has numerous causes, including:
- Cataracts: Clouding of the eye’s lens.
- Dry Eye Syndrome: Lack of sufficient tears to lubricate and nourish the eye.
- Glaucoma: Increased pressure in the eye damaging optic nerve fibers.
- Macular Degeneration: Damage to the macula, leading to central vision loss.
- Diabetic Retinopathy: Complications from diabetes affecting blood vessels in the retina.
Living with Vision Loss Daily
Living with vision loss involves adapting daily routines and finding ways to maintain independence. This includes using assistive devices, learning new skills, and seeking support from organizations dedicated to helping those with visual impairments.

The types of vision loss include:
- Low Vision: Severe but not total blindness.
- Total Blindness: Complete loss of sight in both eyes.
- Tunnel Vision: Loss of peripheral vision, leaving only central vision.
Symptoms of Vision Decline to Watch For
Common symptoms indicating potential vision decline include:
- Difficulty reading or recognizing faces.
- Frequent headaches and eye strain.
- Hazy or blurred vision.
- Sensitivity to light.
