As the days grow longer and the Toronto sun shines brighter over High Park and the West End, patio season and sun safety take center stage.
While we are diligent about applying SPF to our skin, we often overlook our eyes. Summer brings unique ocular challenges like intense UV rays, seasonal allergens, and drying air conditioning.
Here is a quick, highly scannable guide from Symington Pharmacy to keep your vision clear and comfortable all summer long.
1. UV Radiation & Your Eyes
Long-term UV exposure without protection damages the structures of the eye and increases the risk of serious conditions:
- Photokeratitis: A painful "sunburn of the eye" that causes redness, blurred vision, and a gritty sensation.
- Cataracts: A clouding of the eye’s natural lens that ultimately leads to vision loss.
- Macular Degeneration: Potential retinal damage that can increase the risk of age-related macular degeneration (AMD).
- Pterygium: A non-cancerous growth on the white part of the eye that can distort vision.
The Fix: Look for lenses specified as 100% UV protection or UV400 and higher to block both UVA and UVB rays. Consider wraparound styles to stop peripheral sunlight from entering through the sides.
2. Combating "Summer Dry Eye"
Blasting the air conditioning in offices and cars strips moisture from the air, causing tears to evaporate rapidly. Spending time outdoors in the heat also causes systemic dehydration.
- Use Artificial Tears: Drops like Systane Ultra or Refresh Tears supplement natural tears and provide a protective coating that prevents evaporation.
- Adjust Your Environment: Use a humidifier indoors to add moisture back into air-conditioned spaces.
- Hydrate Internally: Drink plenty of water daily; a dehydrated body cannot produce the tear volume needed to keep eyes moist.
3. Managing Seasonal Allergies
Toronto’s lush greenery brings high pollen counts, frequently triggering allergic conjunctivitis. Symptoms include intense itching, watering, and puffiness.
- Stop Rubbing: Rubbing releases more histamine, which worsens the itch , and can cause micro-scratches on the cornea.
- Cold Compresses: A clean cloth soaked in cold water significantly reduces swelling and soothes burning sensations.
- Antihistamine Drops: Targeted over-the-counter options like Visine for allergies or Claritin Eye Drops block the histamine response directly to reduce redness and itching for up to 12 or 24 hours
4. Swimming Safety: Chlorine and Bacteria
Whether you are heading to the pool or taking a trip to a cottage, water safety includes eye safety.
- Chlorine Irritation: Chlorine is a chemical irritant that washes away the protective tear film, leaving eyes red and sensitive.
- Natural Water Risks: Lakes and rivers contain microorganisms and bacteria that can cause serious infections.
- The Contact Lens Rule: Never wear contact lenses while swimming, as they trap bacteria against the cornea. Use airtight goggles over them or dispose of the lenses immediately after exiting the water.
5. Nutrition for Vision Support
Summer is the best time to take advantage of fresh, local produce, which is a powerhouse for ocular health. Certain nutrients are clinically proven to protect the macula and maintain lens clarity.
- Lutein & Zeaxanthin: Found in leafy greens and corn; these antioxidants act as "internal sunglasses" to filter out harmful blue light.
- Vitamin C: Abundant in summer berries and citrus; it supports the health of ocular blood vessels.
- Omega-3 Fatty Acids: Found in walnuts and flaxseeds; these are essential for proper tear production.
For those who find it difficult to get enough of these nutrients through diet alone, a targeted supplement like Vitalux Advanced or Jamieson Lutein can provide the specific ratios of antioxidants recommended by major eye health studies to support long-term vision.
6. Screen Glare & Outdoor Work
Remote outdoor work forces your eyes to work significantly harder due to sun glare reflecting off screens.
- The 20-20-20 Rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds to let focusing muscles relax.
- Go Polarized: Ensure your sunglasses have polarized lenses, which filter out horizontal light reflections from screens and water to prevent headaches.
7. Quick First Aid for Summer Irritants
From sand at the beach to dust on a hiking trail, foreign objects in the eye are a common summer mishap.
- Flush, Don't Rub: Rubbing a piece of sand can scratch the cornea. Flush it out using a dedicated eyewash or sterile saline solution like Multi-Action Solution.
- Watch for Red Flags: See a healthcare professional immediately if you experience sudden vision loss, flashes of light, or persistent pain.
