The College of Optometrists has launched a short video listing a range of amazing eye facts to mark the seventh annual National Eye Health Week. The video, which is available on the the College’s site Look After Your Eyes lists the below fascinating eye facts to explain the importance of the eye and encourage consumers to ensure they have regular sight tests:

 

  1. We produce over 1 litre of tears every year to keep our eyes lubricated. This doesn’t include the emotional tears produced when we cry.
     
  2. Your pupils dilate when you find a person attractive. Some studies suggest women’s pupils are widest during ovulation and this may be why men find partners with wide dilated pupils more attractive.
     
  3. Our eyes are equivalent to a 74 mega pixel camera, but after our brains have processed the image, we can see at a level of detail equivalent to a 576 mega pixel camera, if one existed.
  4. The surface of the cornea is the quickest healing part of the body.
  5. On average, we blink 13,662 times each day. Using a computer for 5 hours a day can reduce this to around 10,350, which may make your eyes feel dry and tired
  6. Our iris is unique, just like a fingerprint.
  7. The human eye can see at least 2.3 million colours. Some research suggests we can actually see up to 7 million!
  8. We have around 4.6 million colour photoreceptors in the eye called cones that enable us to see colour and detail, and over 92 million black and white photoreceptors called rods that help us see in low light.
     
  9. About 8 per cent of all males are colour deficient and perceive colours slightly differently to the majority of us.
     
  10. Your retina is one of the highest oxygen-consuming tissues in your body.

Dr Susan Blakeney, Clinical Adviser to the College of Optometrists, said: “Our research has shown that 64% of British people value their sight more than any other sense and National Eye Health Week presents us with an opportunity to talk about our amazing eyes and how to maintain your vision. As always, if you notice any changes in your vision, then you should book yourself in for a sight test. Regular eye examinations should form part of everyone’s health routine, after all looking after your eyes is just as important as looking after the rest of your body.”

Note to editors:

  1. The letters FCOptom or MCOptom after an optometrist’s name means that he or she is a fellow or member of the College of Optometrists.Membership of the College shows their commitment to the very highest clinical, ethical and professional standards, so look for these letters to see if your optometrist is a member.
     
  2. To find an optometrist who is a member of the College locally and for information and advice about how to look after your eyes visit: www.lookafteryoureyes.org
     
  3. Previously known as ophthalmic opticians, optometrists are trained professionals who examine eyes, test sight, give advice on visual problems, and prescribe and dispense spectacles or contact lenses. They also recommend other treatments or visual aids where appropriate. Optometrists are trained to recognise eye diseases, referring such cases as necessary, and can also use or supply various eye drugs.
  4. Optometrists study at university for at least three years and participate in a full year of training and supervision, called the pre-registration year, before qualifying. Once qualified, they have the opportunity to develop their interests in specialist aspects of practice such as contact lenses, treating eye diseases, low vision, children’s vision and sports vision.
  5. There are currently over 15,000 registered optometrists in the UK
     
  6. The College of Optometrists is the professional, scientific and examining body for optometry in the UK, working for the public benefit.
