An eye stroke, also known as retinal artery occlusion, is a condition where the blood flow to the retina is blocked, leading to sudden vision loss. The retina is the layer at the back of the eyeball that senses light and sends signals to the brain, allowing us to see. When the blood supply to the retina is interrupted, the lack of oxygen and nutrients can cause serious damage to retinal cells, potentially resulting in permanent vision impairment.
Types of Eye Stroke
- Central Retinal Artery Occlusion (CRAO): This occurs when the main artery supplying blood to the retina is blocked. It often results in sudden, painless vision loss in one eye.
- Branch Retinal Artery Occlusion (BRAO): This happens when one of the smaller branches of the retinal artery is obstructed, leading to partial vision loss.
Causes and Risk Factors
- Blood Clots: Clots can travel through the bloodstream and block retinal arteries.
- Atherosclerosis: Hardening of the arteries can narrow or block retinal arteries.
- Carotid Artery Disease: Plaque buildup in the carotid arteries can reduce blood flow to the eyes.
- Heart Disease: Conditions like atrial fibrillation can increase the risk of blood clots.
- High Blood Pressure: Elevated blood pressure can damage blood vessels.
- Diabetes: This condition can lead to vascular complications, including eye strokes.
How to Protect Our Eyes During a Heatwave
1. Wear Sunglasses
Choose sunglasses that block 100% of UVA and UVB rays. Prolonged exposure to UV rays can damage the cornea and retina, increasing the risk of cataracts and macular degeneration.
2. Stay Hydrated
Drink plenty of water to maintain overall hydration, which is crucial for eye health. Dehydration can lead to dry eyes and discomfort.
3. Use Protective Eyewear
If you’re working outdoors or engaging in activities where debris could fly into your eyes, wear protective goggles. This prevents injury and irritation.
4. Avoid Direct Sunlight
Stay indoors or in shaded areas during peak sun hours (10 AM to 4 PM) when UV radiation is strongest. This reduces the risk of eye strain and UV damage.
5. Wear a Hat
A wide-brimmed hat can provide additional protection from the sun, shielding your eyes and face from harmful rays.
6. Use Artificial Tears
Heat and dry air can exacerbate dry eyes. Use artificial tears to keep your eyes moist and comfortable.
7. Maintain Good Hygiene
Avoid rubbing your eyes with dirty hands, especially during a heatwave when sweat and dirt can cause infections.
8. Limit Screen Time
Excessive screen time can strain your eyes, especially in hot, dry conditions. Take regular breaks and use the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.
9. Be Aware of Allergens
Heatwaves can increase airborne allergens, which can irritate your eyes. Keep windows closed, use air purifiers, and avoid outdoor activities during high pollen times.
Eye Stroke and Heatwave: Essential Tips for Protecting Your Vision
An eye stroke is a serious condition that requires immediate medical attention to prevent permanent vision loss. Protecting your eyes during a heatwave is equally important to maintain overall eye health. By following these tips, you can reduce the risk of damage and keep your eyes safe in extreme temperatures.
