Relationship between Ultraviolet Radiation and Your Eyes

What is UV?

UV stands for “Ultraviolet Radiation” which the sun emits. The most common types which can result in serious effects are UVA & UVB to eyes and skin. There are certain factors which will determine how much risk is caused:

  • Geographic location
  • Time of day
  • Altitude

Additional factors that increase the risk are medications and where you are staying. In case, your area has a lot of reflective surfaces like snow & sand then UV exposure is the highest.

People think seasonal changes can leave a greater impact but this is not true. The sun rays are harmful in summer but the winter can also be dangerous.

What is the reason your eyes are at risk?

Given below are some of the eye problems which need to be addressed by the eye doctor so that the condition does not create more complications:

 

  • Cataracts

 

According to WHO, 20% of the cataract cases are due to UV radiation and can be prevented when you visit the eye hospital at the right time.

 

  • Macular Degeneration

 

The macular degeneration linked to age is the main reason for blindness in people that are of age 60 and older. The issue of early AMD is linked with UV exposure.

 

  • Photokeratitis

 

This is referred to as snow blindness which is like a sunburn on the cornea. This condition results in a temporary vision loss.

 

  • Cancer

 

Eyelid tumor is related to UV radiation exposure. Studies have shown that 1/10th of skin cancer is on the eyelid.

 

  • Pingueculae and Pterygia

 

This can distort the vision and corneal issue due to visible growth on the eye surface.

Keep in mind, once the eye damage which is already there cannot be undone. So, it is best to seek medical advice at the right time instead of making it worse.

What can I do to stay safe?

  • You need to understand the importance of sunglasses as they will protect the eyes against the UV rays. Make sure that you choose the shades which block the UV rays 100%.
  • Also, the lens color is not going to make any difference whether it is brown, grey, or amber.
  • The frame style also plays an essential role. You should choose the wraparound and close-fitting style. If you want another layer of protection then the wide-brimmed frame is best.

If you are facing any eye-related issue then do not avoid it because if it gets aggravated then it can cause serious complications.
