There are several other factors that can affect your eye health, according to the NHS.

The health body says: “If you smoke you’re much more likely to develop age-related macular degeneration, which is the most common cause of sight loss in the UK, and cataracts, than people who do not smoke.”

It adds: “Getting out in the sun is important for your general health, but you need to protect yourself. Never look at the sun directly, even when something exciting such as an eclipse is happening.”

Age UK notes: “Vision problems can lead to a higher risk of falls, driving accidents, and incorrect use of medications. They can also make day-to-day life harder. The best way to make sure your eyes are healthy is to have regular eye checks. Many eye diseases can be treated successfully if they are detected early.”
