Keeping Your Eyes Safe in the Summer Sun: Essential Tips and Protection Strategies


With the arrival of summer, many of us seek to rejuvenate and reconnect with nature. It’s crucial to remember the potential dangers of bright rays –  ultraviolet (UV) radiation. Just like you wouldn’t step outside without sunscreen, protecting your eyes during the summer is vital for maintaining good eye health and preventing potential damage.

How UV Exposure Affects Your Eyes

The sun emits two main types of UV rays: They are UVA and UVB. While UVB rays are the culprits behind sunburns, both UVA and UVB can penetrate the cornea and lens of your eye, leading to a variety of issues:

  • Sunburn on the Eyes (Photokeratitis): Ever felt like you have sand trapped under your eyelids after a long day at the beach? This painful and irritable condition, is essentially sunburn on the cornea caused by excess UV exposure.
  • Cataracts: Studies suggest prolonged sun exposure can increase your risk of cataracts, a clouding of the lens that can significantly impair vision.
  • Age-related Macular Degeneration (AMD): AMD is a leading cause of vision loss in older adults, and excessive UV exposure is thought to be a contributing factor to AMD.
  • Pterygium (Surfer’s Eye): This non-cancerous growth of tissue on the white part of the eye (near the corner) can be caused by chronic UV exposure. While usually benign, it can sometimes affect vision and require removal.
  • Skin Cancer Around the Eyes: The delicate skin around the eyes is particularly vulnerable to UV rays, increasing the risk of skin cancer development.

Keeping Your Eyes Safe: Essential Eye Protection Strategies

Now that we understand the risks, let’s explore some key strategies to keep your eyes safe in the summer sun:

  • Sunglasses: Your Essential Summer Shield: Invest in a good quality pair of sunglasses that block 99% of both UVA and UVB rays. Look for ones labeled “UV 400” – this means they block all wavelengths up to 400 nanometers, which covers the entire UVA and UVB spectrum.
  • Polarised Lenses for Extra Comfort: Consider polarised lenses. These lenses filter out scattered light and glare, reducing eye strain and making it easier to see outdoors, especially on bright days or near water. Wraparound sunglasses provide additional protection from the sides, blocking sunlight that might sneak in and damage your eyes.
  • Shade, Your Summer Sanctuary: Whenever possible, take breaks from direct sunlight, especially during peak hours (10:00 AM to 4:00 PM). Relax under an umbrella, find a shady spot under a tree, or plan outdoor activities for earlier or later in the day when the sunlight is not so concentrated.
  • Sunscreen for Your Eyelids Too! Don’t forget to apply sunscreen with SPF 30 or higher to your eyelids and the delicate skin around your eyes. Choose a broad-spectrum sunscreen for optimal protection.
  • Regular Eye Exams: Your Eye Health Baseline: Schedule regular check-ups with your ophthalmologist (eye doctor) to monitor your eye health and detect any potential sun-related damage early on. Early detection and intervention are crucial for maintaining good vision.

Selecting the Right Sunglasses: A Guide for Top-Notch Eye Protection

Choosing the right sunglasses goes beyond just complimenting your outfit. Here are some key factors to consider:

  • UV Protection: As mentioned earlier, prioritise sunglasses that block 99% of UVA and UVB rays. Look for the “UV 400” label for guaranteed protection.
  • Lens Material: Polycarbonate lenses are a great choice for durability and impact resistance, ideal for active individuals who tend to be outdoors. Trivex lenses offer similar benefits with the added advantage of being lighter.
  • Lens Color: While darker lenses might seem more protective, the colour itself doesn’t necessarily determine UV blocking ability. Look for a reputable brand that prioritises UV protection regardless of lens colour.
  • Fit is Crucial: Sunglasses should fit comfortably and securely on your face without slipping or creating gaps where UV rays can enter. Consider a slightly wrap-around style for additional coverage.

Summer Eye Care: Beyond Sunglasses

Here are some strategies to implement that we recommend beyond Sunglasses :

  • Hydration is Key: Drinking plenty of water throughout the day helps keep your eyes hydrated and reduces the risk of dry eye, an eye syndrome that can worsen with sun exposure.
  • Reduce Screen Time Outdoors: The combination of bright sunlight and screen glare can put additional strain on your eyes. Limit screen time while outdoors, especially during peak sun hours.
  • Healthy Diet for Eye Health: Include plenty of fruits and vegetables rich in antioxidants in your diet, as they can help protect your eyes from sun damage.Fruits like Citrus fruits, Berries,Bananas and Veggies like Spinach,Broccoli and Carrots are really good to beat the Summer Strain.
  • Protective Eyewear for Specific Activities: For certain activities like water sports, snow sports, or intense outdoor work, consider specialised protective eyewear. Goggles can provide a secure fit and additional protection from wind, dust, and debris.
  • Don’t Forget Your Contacts: If you wear contact lenses, be extra vigilant about eye care during the summer. Dry eye can become a bigger issue with sun exposure, so make sure to use lubricating eye drops regularly and consider switching to daily disposable lenses to minimise the risk of infection.
  • Be Mindful of Medications: Certain medications can increase sun sensitivity. Talk to your doctor if you experience any changes in your vision or discomfort while taking medications.
