Depending on the cause, several natural strategies and lifestyle changes can help improve vision.

Rest and recovery

The eyes are sensitive organs that require rest, just like other body parts. Ensure you get enough quality sleep. When working on a computer for extended periods, follow the 20-20-20 rule: every 20 minutes, look at an object 6 m away for 20 seconds.

Keep eyes hydrated

If blurred vision stems from dry eyes, blink often or gently massage your eyelids with a warm compress. This stimulates the meibomian glands, which produce oil for tears. Artificial tears can also maintain the eye's surface moisture, reducing dryness from visual strain.

Protect eyes, improve air quality

Wear sunglasses outdoors to shield your eyes from ultraviolet (UV) rays, prioritizing those that block both UVA and UVB. Sunglasses also help in cold, dry weather by limiting wind irritation. In dry climates, a humidifier can reduce dry eye risk. Avoid direct airflow to your face, particularly at night.

Quit smoking

Smoking raises the risk of numerous eye conditions, including age-related macular degeneration, cataracts, and optic nerve damage. Smoke also exacerbates dry eye symptoms.

Avoid allergens

To prevent and manage allergies, limit exposure to triggers. For instance, if you are allergic to dust, clean your bedroom regularly to prevent dust buildup, which can irritate your eyes during sleep. For outdoor allergies, keep windows closed and use air conditioning with air filters to reduce allergens. If these steps are insufficient, discuss antihistamine eye drops with a doctor.

Supplement omega-3 fatty acids, vitamin A

Incorporating omega-3-rich foods like fatty fish, flaxseeds, and walnuts into your diet can benefit individuals with dry eye symptoms. If considering omega-3 supplements, consult a doctor due to potential drug interactions. A vitamin A deficient diet can cause dry eyes and other vision issues, including blurred vision. Carotenoids, precursors to vitamin A, are present in plants such as sweet potatoes, carrots, kale, and pumpkins. The daily recommended vitamin A intake is approximately 900 mcg for men and 700 mcg for women.

Practice proper contact lens hygiene

If you wear contact lenses, wash your hands before handling them and follow proper cleaning procedures. Disinfect lenses according to manufacturer instructions and avoid sleeping with contact lenses, as this poses risks to eye health.

If your vision becomes progressively blurred and persists, seek evaluation from an eye care specialist for a comprehensive eye exam and any necessary further tests.
