It’s no secret that the sun is a powerful force. It can give us warmth and energy on a cold day, or make us feel like we’re on holiday when we’re stuck in the office. But the sun can also be harmful to our health – especially our eyes. In this blog post, we’ll discuss how sunlight exposure can damage our eyes, and what steps we can take to protect them.
If you work outside, or in an environment where there is a lot of sunlight exposure, it’s especially important to take steps to protect your eyes. Eye damage from the sun can lead to vision problems down the road, so it’s crucial to take action now.
Why does the sun damage eyes?
The sun emits ultraviolet (UV) rays, which are a type of electromagnetic radiation. This radiation is invisible to the human eye, but it can be harmful to our health. When UV rays hit the retina, they can damage the cells in that area.
What kind of damage can sunlight exposure do to eyes:
- Solar retinopathy: a condition that occurs when the retina is damaged by too much exposure to sunlight. Solar retinopathy can cause vision problems like blurriness, dark spots, and even blindness.
- Cataracts: when the lens of the eye becomes cloudy, leading to blurry vision and other vision problems.
- Macular degeneration: an age-related condition that causes vision loss in the centre of the field of vision.
- Pterygium: a growth develops on the white part of the eye. A pterygium can cause redness and irritation, and can eventually lead to scarring and vision problems.
How to protect your eyes from the sun:
- Wear sunglasses that block out UV light – look for a pair that blocks 99% or 100% of UV rays. Make sure to choose a pair that wraps around your head and covers your entire field of vision – the wider the better.
- Wear a wide-brimmed hat to shade your face and eyes.
- If you wear contact lenses, talk to your eye doctor about UV-blocking lenses that offer UV protection.
- Be sure to limit your time in direct sunlight, especially during the middle of the day when the sun’s rays are strongest. When possible, stay in the shade.
- Take breaks: if you are outside for an extended period of time, take breaks indoors or in the shade to give your eyes a rest from the sun.
Symptoms of eye damage from sunlight exposure:
There are a number of symptoms that can indicate you have suffered eye damage from the sun. These include:
- Blurred vision
- Trouble seeing at night
- Changes in colour vision
- Floaters or spots in your field of vision
- Frequent changes in eyeglass prescription
- Redness or irritation in the eyes
- Sensitivity to light
If you experience any of these symptoms, make an appointment with your eye doctor as soon as possible. Only a professional can properly diagnose and treat sun-related eye damage. They will be able to determine if you have eye damage and, if so, what treatment options are available.
Treatments for eye damage from sunlight exposure:
Cataracts and Pterygium are often treated with surgery. There is no cure for solar retinopathy, but there are treatments that can help improve vision. These include wearing sunglasses or other protective eyewear, avoiding direct sunlight exposure, and using artificial tears to lubricate the eyes. If your vision is still blurry after these treatments, your doctor may suggest that you see a retina specialist for further treatment.
While eye damage from sunlight exposure can be serious, it’s important to remember that it is preventable. Eye damage from the sun is also cumulative, so the steps you take to protect your eyes now can help reduce your risk of developing eye damage down the road. So next time you head outdoors, don’t forget to grab your sunglasses and hat!
