What is low vision?

I have read two definitions:

  • “Low vision is the term used to refer to a visual impairment that is not correctable through surgery, pharmaceuticals, glasses or contact lenses. It is often characterised by partial sight, such as blurred vision, blind spots or tunnel vision. Low vision can impact people of all ages, but is primarily associated with older adults.”and,
  • “Low vision is ‘not enough vision to do whatever it is you need to do’, which can vary from person to person”.

Your vision can deteriorate with age; however, vision loss does not have to be an accepted part of growing old. A yearly eye examination by an optometrist or vision specialist can identify potential vision problems before they occur. In my case a simple trip to the optometrist to organise a new pair of reading glasses revealed the fact I have Age Related Macular Degeneration. I still needed the new reading glasses, and I was given a referral to an eye specialist who is now treating my macular disease.

Because of this early diagnosis the specialist has told me “I will have very useful vision for a long time”. I am now 63 and a bit so ‘a long time’ sounds like very good news to me.
Some of the more common causes of low vision include:

Age Related Macular Degeneration (AMD): AMD is the leading cause of vision loss, for example in the USA it accounts for nearly 50% of all low vision cases. It is caused when the macular breaks down which can cause the loss of central vision, please see this link for more information about AMD.

Glaucoma: is the second major cause of low vision and it can occur without warning. For more info about glaucoma please use this link.

Diabetic Retinopathy: Diabetic retinopathy affects blood vessels in the retina at the back of the eye. It is a major cause of blindness and it is the most common cause of vision loss among people with diabetes.

Cataracts: Most of the eye’s lens is made of water and protein, and the protein is arranged in an exact way to keep the lens clear. As we grow older some of the protein may clump together creating a cataract. Over time, it may grow larger and cloud more of the lens, making it harder to see.

Vision is also an important factor in maintaining balance. Since 2011 In the USA the rate of life-threatening injuries after a fall since has nearly doubled when compared to the previous decade.

It is a shock when you discover your vision loss cannot be reversed, however please remember it can be treated. So, organise the professional help that will provide you with the strategies and treatments to keep you active and safe.
