Summer, Sunshine, Sunglasses!

The sun is shining and you’re breaking out the shorts and flip flops. That means one thing, summer is officially here!

While many of us are basking in the glorious sunshine, topping up our tans and enjoying some much-needed vitamin D, it’s important to remember the harmful effects of prolonged UV light exposure and take action to protect yourself against sun damage to your eyes.

What Is UV Light?

Our principal optometrist, Mr Kasmani, answers a few frequently asked questions from our patients below so you’re in the know about this summer about all things UV and sunshine.

What Is UV Light?

Ultraviolet light is a type of electromagnetic radiation that comes from the sun. There are two kinds of rays that can cause damage to a person’s skin and eyes: ultraviolet A (UVA) and ultraviolet B (UVB).

What Are The Risks Of UV Exposure?

What Are The Risks Of UV Exposure?

UVB rays can reach the front surface of your eyes, i.e., the cornea, while UVA rays can pass through your cornea and enter the thin layer of tissue at the back of your eye, known as the retina.

Prolonged exposure to UV can cause serious short and long-term damage to your eyes.

What Are The Short-Term Risks Of UV Exposure To The Eyes?

Intense exposure to UVB rays can cause a condition called photokeratitis. This is like getting sunburn on your cornea and conjunctiva. It often only lasts for a couple of days, but the condition can be very painful, and you may have red, watery eyes, and blurred vision during this time.

What Are The Long-Term Risks Of UV Exposure?

What Are The Long-Term Risks Of UV Exposure?

Over the years, prolonged exposure to UV rays can increase your risk of developing cataracts later in life, which is when the lens of your eye becomes cloudy, as well as age related macular degeneration, which irreversibly damages the retina and causes central vision loss.

How Can I Protect Myself From The Damaging Effects Of UV Exposure?

It’s important to make sure you:

  1. Wear sunglasses with 100% UV protection when you’re outside, even when it’s overcast
  2. Take a wide-brimmed hat with you to shade your eyes
  3. Limit the amount of time you spend in the sun, avoiding peak hours if possible
