Eye Stroke: An Eye Protection Guide To Brave The Heatwave

A significant concern during extreme heat is the risk of an eye stroke. But what exactly is an eye stroke, and how can you safeguard your eyes during intense heat? Here's a detailed guide.

What is an eye stroke?

An eye stroke, or retinal artery occlusion, occurs when blood flow to the retina is blocked. The retina is crucial for receiving light and transmitting visual information to the brain. A disruption in its blood supply can lead to sudden vision loss and permanent damage. Risk factors for an eye stroke include high blood pressure, diabetes, and high cholesterol. During heatwaves, the risk escalates due to dehydration and increased blood thickness, making blockages more likely.

Symptoms to watch out for

Symptoms of an eye stroke can appear suddenly. These include sudden vision loss in one eye, visual disturbances like shadows or dark spots, partial or complete loss of visual fields and painless vision changes.

Dehydration and dry eyes

Heatwaves often lead to dehydration, which can cause dry eyes. This condition occurs when your eyes don't produce enough tears or the tears evaporate too quickly, causing discomfort, redness, and a gritty feeling.

Increased risk of eye infections

Sweating more during heatwaves can increase the risk of eye infections. Sweat can carry bacteria that might enter your eyes, especially if you touch them frequently, leading to conjunctivitis (pink eye) and other infections.

UV radiation exposure

Heatwaves are typically accompanied by high levels of UV radiation, which can damage your eyes. Prolonged exposure to UV rays can result in cataracts and macular degeneration, both leading to serious vision problems.

Stay hydrated

Maintaining hydration is essential. Drink plenty of water to keep your eyes moist and avoid dehydration, which can worsen dry eyes. Aim for at least eight glasses of water daily, and increase intake if outdoors or sweating heavily.

Wear protective eyewear

Sunglasses are vital for eye protection against UV rays. Choose sunglasses that block 100% of UVA and UVB rays to prevent damage from sun exposure. Additionally, wide-brimmed hats can provide extra shade for your eyes.

Avoid direct sunlight

Limit your exposure to direct sunlight, especially during peak hours between 10 a.m. and 4 p.m. When outside, seek shade and take frequent breaks to cool down.

By understanding the risks and taking preventive measures, you can protect your eyes from the detrimental effects of heatwaves. Stay vigilant and keep your eyes safe during extreme heat conditions.
