There are many things that people can do to maintain eye health, though something many overlook is following a good diet, it has been noted.
Nutritionist Sarah Schenker, speaking on behalf of The Nutrition Society, said there are a few nutrients that are particularly important for eye health and there also some plant chemicals that are vital.
These are often not classified as essential nutrients, but it is well-known that when you eat them in fruit and vegetables they have a positive impact on eye health.
The expert explained that the kind of things you would find them in are berries, as well as anything that has a strong colour or pigment, while they can also be found in dark fruits.
Ms Schenker added: "We also have essential requirements for things like Vitamin A which exists in the form of two things in our diets - in Retinol and Beta Carotene, which you find in the orange, red and yellow coloured vegetables and fruits.
The likes of red peppers, carrots, melon and apricots all contain the Beta Carotene form of Vitamin A, while Retinol is found in full fat milk yogurt, meats and fish and anything that has a fat component in it, the expert explained.
"Most important to health is if you have a deficiency of Vitamin A in your diet then that is linked with night blindness and it is an important part for your eyes to adapt to dim light," she stated.
The expert said that all vitamins and minerals will have some kind of interplay in keeping cells in the body healthy, but Vitamin A is particularly important, as well as the plant chemical found in berries known as Lutin.
