Eyesight (poor)
Synopsis
Poor eyesight refers to a reduction in the clarity or sharpness of vision, which can affect distance, near, or both types of focus. It may be gradual or sudden, temporary or permanent, and result from refractive errors (the most common cause) or underlying eye diseases, systemic conditions, or nutritional deficiencies.
The most common causes include:
-
Refractive errors: myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related difficulty focusing on close objects)
-
Eye diseases: cataracts, glaucoma, macular degeneration, and diabetic retinopathy
-
Dry eyes and digital eye strain from prolonged screen use
-
Nutritional deficiencies, especially in vitamin A, zinc, or antioxidants
-
Systemic issues: high blood pressure, diabetes, or neurological disorders
Poor eyesight may also be caused or worsened by environmental factors like poor lighting, UV exposure, or not using corrective lenses when needed. While some vision issues are reversible or correctable with glasses, contacts, or surgery, others—especially degenerative or chronic conditions—require long-term management to slow progression.
When to see a doctor:
Seek medical care if experiencing sudden changes in vision, double vision, flashes of light, loss of peripheral vision, eye pain, or if poor eyesight interferes with daily activities. Early detection and intervention can prevent permanent loss in many conditions.
Natural Remedies
Eye Exercises: Techniques like near-far focus and palming may support flexibility and relaxation of eye muscles.
Limit Screen Time: Use blue-light filters, take regular breaks (20-20-20 rule), and ensure proper ergonomics.
UV Protection: Wear sunglasses with UV400 protection to guard against retinal damage.
Adequate Lighting: Prevent eye strain by reading or working in well-lit environments.
Balanced Diet: Emphasize colorful vegetables, leafy greens, omega-3s, and protein for eye tissue repair.
