Living in San Diego means enjoying beautiful, sunny weather for most of the year. It’s easy to think of sun protection as a summer-only task, something you remember when you pack a bag for the beach. Many people are surprised to learn their eyes need protection from ultraviolet (UV) rays every day, regardless of the season. That’s why a comprehensive eye exam includes a discussion of your lifestyle and how to best protect your vision.
Yes, you need year-round UV protection for your eyes to maintain your long-term vision health in San Diego. The sun’s rays are a constant presence, and the cumulative effects of exposure can impact your eyes over time. Simple, daily habits can make a significant difference in protecting your sight.
San Diego’s Sun Isn’t Just for Summer
The Myth of a Cloudy Day
You may not feel the sun’s warmth on an overcast day, but that doesn’t mean your eyes are safe. A large percentage of UV rays can penetrate cloud cover, reaching your eyes and skin. This is why you can still get a sunburn on a cloudy day—and your eyes can experience similar effects without the right protection.
Reflections from Water and Sand
A trip to the coast involves more than just direct sunlight. UV rays bounce off surfaces like water, sand, and even pavement, increasing your total exposure. This reflected light can be just as potent and requires the same level of attention as the sun shining from above.
When UV Rays Are Strongest
The sun’s intensity is typically highest between 10 AM and 4 PM, a fact that holds true for every season. Even on your morning or evening commute, the sun’s lower angle during fall and winter can lead to more direct eye exposure. Since the UV index can be high in any month, relying on the temperature is not a dependable method for protecting your eyes from sun damage.
How UV Light Affects Your Eyes
Short-Term Eye Concerns
Have you ever had eyes that felt red and gritty after a long day outside? You may have experienced photokeratitis, which is like a sunburn on the surface of your eye. This temporary condition can be uncomfortable and may include symptoms such as:
- Redness or irritation
- A sandy or gritty feeling
- Extreme sensitivity to light
Long-Term Vision Problems
The effects of UV exposure add up over your lifetime. Unprotected exposure can contribute to several eye conditions, including a higher likelihood of developing cataracts. It can also damage the retina, which may accelerate conditions that affect your sharp, central vision. You might also notice growths on the white part of the eye, which can eventually interfere with your sight.
Choose the Right Eye Protection
What to Look for in Sunglasses
Not all sunglasses are created equal. Your lenses should block 100% of both UVA and UVB rays. While polarized lenses are great for reducing glare, you still need to check the label for full UV-blocking capability. Frames that are larger or have a wraparound style also help by providing more coverage and blocking light from the sides.
Beyond Just Sunglasses
Sunglasses are an important tool, but you can add other layers of defense. A wide-brimmed hat offers excellent shade for your face and eyes. You can also seek shade during peak sun hours and ask your eye care professional about UV-protective coatings on regular glasses or even explore UV-blocking contact lenses.
UV Safety for the Whole Family
Children’s eyes are more vulnerable to sun damage because their internal lenses are clearer than an adult’s, allowing more harmful UV rays to reach the retina. Helping kids build healthy habits—like putting on a hat and sunglasses before they go outside—sets a foundation for a lifetime of good eye health.
Since UV exposure is cumulative, the protection you provide for them today helps support their vision for years to come. Making sure they have regular children’s eye exams is another key step in monitoring and protecting their sight.
Proactive Steps for Your Eye Health
Consistent, preventative care is a key part of keeping your eyes healthy. Regular eye exams allow a professional to check for any early signs of sun-related damage and monitor your overall vision. You can also discuss your lifestyle and outdoor activities, which helps your provider offer personalized advice.
