UV and Your Eyes

Your eyes are sensitive and delicate structures, and just like your skin, are vulnerable to the effects of UV radiation - with the cells in the eyes even able to become sunburnt. Exposure to UV radiation can cause harmful effects, particularly to the cornea, lens, and retina. When this damage accumulates over time, it can lead to:

• Photokeratitis (corneal damage): this is a painful condition that occurs when the cornea is sunburned. It is usually temporary and can cause symptoms such as eye pain, redness, tearing, and sensitivity to light.
• Cataracts: long-term exposure to UV radiation can cause the eye's natural lens to become cloudy in areas, which is known as cataracts. This can cause blurred or reduced vision, sensitivity to light, and trouble seeing at night.
• Macular degeneration: this is a serious condition that affects the central part of the retina and can lead to a loss of central vision. Long-term exposure to UV radiation may increase the risk of developing macular degeneration, alongside the natural ageing process.
• Pterygium: this is a growth of tissue on the conjunctiva, the clear membrane that covers the white part of the eye. Pterygium can cause discomfort, redness, and visual disturbance.

You can help prevent your eyes from excess UV exposure by:

• Wearing sunglasses daily: look for sunglasses that block 100% of UV rays. Your Stacey & Stacey eye care professionals will help you select the best ones for your needs, and your style preferences. Wrap-around styles are best as they provide maximum protection.
• Wearing a hat: wearing a hat with a wide brim can provide additional shade to the eyes and face, reducing UV exposure.
• Limiting exposure during peak hours: try your best to avoid being outside during the peak hours of 10am to 4pm, as this is when UV rays are strongest in Australia.
• Use protective eyewear: if you work or participate in outdoor activities such as skiing or snowboarding, consider wearing protective eyewear with UV protection.
• Wear contact lenses with UV protection: some contact lenses are designed with built-in UV protection. Talk to your optometrist about your options.
• Don't stare at the sun: never look directly at the sun as this can cause permanent damage to the eyes.
• Attend regular eye exams: annual or bi-annual (depending on your age) eye exams can help detect early signs of UV damage and other eye problems.
