“Additionally, changes in blood pressure caused by alcohol reduce how many nutrients and how much oxygen the optic nerve receives, and changes in levels of B12, or thiamine, can also damage vision. There are also some studies which suggest that excessive drinking can lead to an increased risk of cataracts, which is a condition that makes the clear lens of the eye go cloudy or opaque.”
“Your eyes can provide clues to your general health and wellbeing too. People who complete Sober October – or go even longer without booze – may well find their eyes look brighter and feel more comfortable.”
“The whites of the eye, known as the sclera, should be white in colour. If they look yellow it could be a sign of jaundice, which means the liver, gallbladder and bile ducts aren’t working properly. This condition can occur if someone has drunk too much over a long period of time. If the whites of your eyes discolour, this could also be a sign of other health conditions such as blood disorders, anaemia, pancreatitis, or some cancers. We’d urge anyone who has noticed a change in the feel, look or function of their eyes to seek a thorough examination that checks eye health, as well as vision, as soon as possible.”
