To fix a lazy eye (amblyopia), several treatment options are available, especially effective when started early in childhood but also beneficial for older patients:
Common Treatments
- Eyepatching: Covering the stronger eye with a patch for 2 to 6 hours daily forces the brain to use the weaker eye, strengthening its vision. This is a simple and cost-effective method often recommended for children but can also help some adults
- Corrective Eyewear: Glasses or contact lenses correct refractive errors like nearsightedness, farsightedness, or astigmatism that contribute to lazy eye. Proper prescription helps the brain use both eyes more effectively
- Eye Drops: Atropine drops may be used to blur vision in the stronger eye, encouraging use of the weaker eye as an alternative to patching
- Vision Therapy: This is a structured program of eye exercises supervised by specialists (orthoptists or optometrists) designed to improve eye coordination and strengthen the lazy eye. Techniques include using prism lenses, therapeutic lenses, and computer software
- Surgery: In cases where lazy eye is caused by physical issues like droopy eyelid, cataract, or strabismus (crossed eyes), surgery may be performed to correct these underlying problems
Exercises to Support Treatment
Eye exercises can help train the brain and weaker eye to work together better, often used alongside other treatments:
- Pencil pushups: Focusing on a pencil as it moves closer to the nose to improve convergence.
- Brock string exercise: Using a string with beads to practice focusing and eye coordination.
- Dot card exercise: Focusing on dots arranged on a card to improve binocular vision.
- Coloring within lines or playing specially designed video games that stimulate both eyes differently can also be beneficial
Age Considerations
- Treatment is most effective when started before age 7 but can still improve vision in teenagers and adults.
- Adults may benefit from updated glasses prescriptions, patching, and vision therapy to retrain the brain and improve the weaker eye
In summary, fixing a lazy eye typically involves a combination of corrective lenses, patching or atropine drops to encourage use of the weaker eye, vision therapy exercises, and sometimes surgery for underlying causes. Early diagnosis and treatment yield the best outcomes, but improvements are possible at any age with appropriate care
