Keep calm, and get new sunglasses

There is certainly nothing wrong with following you trusted celebrity trends which influence our sunglass purchases, but let’s not lose sight of the importance of sun protection. It is essential to think of sunglasses as sunscreen for the eyes.

Besides giving your eyes colour, melanin helps protect them from the sun. Light eyes such as blue, grey, and green have less pigment which makes them more sensitive to the sun’s harmful rays than brown or black.

Those spending long hours in the sun may suffer from sunburn of the eyes, or Photokeratitis. It is also known as snow blindness as it happens to skiers too. 

Below are just 5 Reasons why you should wear sunglasses in summer

  1. Prevent Eyelid Cancer – Frequent sunburns have been linked to cancer. The eyelids and the skin around the eye are so thin, they are much more susceptible to damage from the sun,
  2. Protect The Retina – The light sensitive membrane at the back of the eye which sends visual messages to the brain can deteriorate over time which leads to vision loss,
  3. Stop Cataracts from forming – The clouding of the lens of the eye leading to reduced vision,
  4. Protect the Cornea from sunburn – The Cornea is the windshield of your eyes.  UVB rays can cause Photokeratitis (sunburn of the cornea)
  5. Protect the Whites of your Eyes – UV rays can cause irritation and inflammation to the conjunctiva (the thin membrane which covers the white of the eyes) which in turn can cause it to swell over the cornea, partially blocking your vision

Consider these shopping tips when making your next sunglass purchase:

  • Ensure that they are 100 percent UV-blocking Sunglasses 
  • Large lenses that will completely cover the eyes – wrap-around style sunglasses, which help cut down on UV entering the eye from the side,
  • Sunglasses do not need to be expensive. What’s important is that your sunglasses offer protection from both UVA and UVB rays, which are both harmful to the eyes,
  • Buy several pairs, this way you will always have a pair when you need them,
  • Polarization reduces glare coming off reflective surfaces like water, snow, or pavement. This is important to prevent sunburn of the eye
