These sunny, yellow-orange flowers are a surprising friend for your eyes as they are rich sources of lutein. In fact, the chances are, if you take a lutein supplement, it is sourced from marigolds.
"Lutein is vital for healthy vision," explains GP and medical nutritionist, Dr Sarah Brewer. "Research published in Optometry – the Journal of the American Optometric Association - shows that taking lutein supplements can improve vision in some cases of age-related macular degeneration (AMD)," she adds. Participants in the study took 10mg daily - five times the average daily intake from diet alone.
Like any part of the body, your eyes need rest too. "Whether it's from close-up work or time spent in front of a computer screen, taking regular breaks from screen time are important to prevent straining your eyes," says GP Dr Rob Hicks.
The 20/20/20 rule is a good one to follow: work for 20 minutes, then look 20 feet away for 20 seconds.
"A great tip for good eye health is to simply 'traffic light' your way to great eye health," says nutritionist Rob Hobson. "Eat plenty of dark-green, leafy vegetables, such as kale, which are high in lutein and zeaxanthin. These are concentrated in the macula of the eye and help to filter out harmful light.
Red and orange foods, such as squash and tomatoes, are rich in lycopene and beta carotene, which help to protect against UV radiation."
"It's important to understand that your eyes are sensitive to stress," says lifestyle doctor Dr Chidi Ngwaba. "It can impact your visual skills in various ways. These include headaches, glasses and contacts never feeling 'right' on your face, difficulty concentrating, watery eyes, sensitivity to light, poor eye-hand coordination and a constant eye twitch."
Deal with your stress by talking to someone or seeking help and finding ways to help you relax.
"Spring and summer can play havoc with our eyes," says Dr Brewer. Seasonal allergic conjunctivitis is normally caused by hay fever, but perennial allergic conjunctivitis can be caused by dust mites and pets.
Try to avoid known allergens where possible and keep a diary to track the severity of symptoms. If symptoms are persistent, chat to your optometrist to see what other options are available to help relieve your discomfort.
