Climate change has been regarded as the most significant health threat to humanity, including ocular health. A study from the University of Colorado Anschutz Medical Campus examined the link between ocular surface irritation and allergy-related daily outpatient office visits with daily ambient particular matter (PM).
Researchers found that clinic visits increased when the daily ambient PM concentration increased. The daily visit counts more than doubled when PM from air pollution was in the atmosphere. These findings suggest that climate change significantly affects eye health, increasing the occurrence and risk of eye maladies like ocular surface irritation, allergies, and conjunctivitis.
Why the eyes are vulnerable
The eyes are directly exposed to the environment, making them incredibly vulnerable to changes in weather conditions and increased pollutants. As climate change worsens these issues through severe environmental and pollution patterns, the eyes can suffer from disorders linked to increased exposure. Eye conditions affected by UV rays may see more cases or accelerated development among patients. Pollutants can cause more frequent and intense ocular problems. This also has significant implications for the economy, as people suffering from vision issues due to climate change may have to visit the doctor more often or can't perform well at work.
How to protect your eyes from climate change's impact
Wear sunglasses
Climate change can increase exposure to the sun's harsh UV rays, especially as greenhouse gases deplete the ozone layer. More UV exposure can affect your eyes, increasing your risk of conditions such as cataracts, macular degeneration, and even cancer around the eye area. Wearing a pair of sunglasses outdoors can protect your eyes, allowing you to prevent or slow the progression of these conditions. A pair with 100% UVA and UVB protection is the most crucial priority, but you can also consider other elements. Larger models offer more coverage from UV rays and pollutants; styles like the Salvador and Itinerary from Eyebuydirect have more oversized frames that can cover the eyes and the skin around them. Wraparound models also protect from UV rays and particles from more angles. You can also consider polarized lenses to block glare from water, snow, and other reflective surfaces.
Hydrate your eyes
Warmer temperatures can cause dry environmental conditions, which can also cause dry eyes or exacerbate existing symptoms. Without sufficient tears, you can experience stinging, irritation, and burning. Severe cases can even lead to corneal abrasions and eye infections, as the tear film isn't enough to protect your eye's surface. Paying attention to your eyes' hydration is crucial for maintaining their health. Blinking frequently helps replenish your tears and prevent dryness. Drinking at least eight glasses of water a day also promotes eye moisture. If you wear contact lenses or need an extra lubrication boost, you can use eye drops to provide relief. The Systane Complete Preservative-Free Lubricant Eye Drops work for all kinds of dry eyes and can keep them hydrated for up to eight hours.
Improve your indoor air quality
Managing pollution outdoors isn't always feasible, but you can control the air quality in your home to minimize exposure to particles and pollution for better eye health. One easy way to maintain indoor air quality is by increasing ventilation. Opening windows and doors for ten to fifteen minutes can bring fresher outdoor air to dilute indoor pollution. If your home is near a pollution source, like a busy road, consider installing air purifiers that trap particles and pollutants in the air and release cleaner air. Some indoor plants even have air-purifying qualities, including the spider plant and Chinese evergreen; planting them in the home can make the air fresher and cooler. It's also vital to avoid products with aluminum; case in point, some stick deodorants have propylene glycol, which can irritate the eyes. Purelygreat deodorants are a safe EWG Verified™ choice. By limiting the amount of pollutants and particles indoors can keep your eyes safe and comfortable for longer.
