This months' World Sight Day, Specsavers across Cornwall are sharing five surprising things that can have an effect on our eyes.

What you many may not realise is that the food we eat, the things we do with our day and even our makeup can all make an impact on our eyes.


Rachel McClelland, Ophthalmic Director Specsavers Launceston, explained: ‘When we don’t have enough tears to lubricate our eyes they can become dry and irritated and we can even start to get slightly blurred vision. Tears are so important as they can wash away foreign matter that might come into contact with your eye and they also help reduce the risk of eye infections.’

Eating fish

Eating plenty of fish which is high in omega 3 fatty acids can help with eye lubrication.

Rachel said: ‘When an individual has a dry eye the surface of the eye becomes inflamed. This inflammation further damages the cells which are responsible for tear production, resulting in a vicious circle of increasing inflammation and dryness. It is well documented that omega 3 essential fatty acids have anti-inflammatory effects and therefore may offer some degree of protection against dry eye.’


If you ever feel your eyelids twitching from time to time, you might be experiencing myokymia. Myokymia causes spasms which are often uncomfortable and distracting and can be caused by lack of sleep.

Rachel said: ‘It’s essential that we all get enough sleep as it gives our bodies an opportunity to rest – including our eye muscles, which will help to stop them from twitching.’


Rachel said: ‘Not only are avocados rich in zinc and vitamin B which help stave off cataracts, but they also have a high amount of lutein. Research suggests lutein is a carotenoid which helps filter out blue light, helping to prevent age-related macular degeneration.’


Rachel said: ‘Leaving your eye makeup on when you go to sleep will increase your chances of getting bacterial and oil build up around your eyes or even inflammation. Make sure you always gently remove beauty products to reduce infection and keep your eyes clean.’

Your eyes can reveal a lot about your health so it’s really important to have regular eye tests – once every two years, or more often if recommended by your optometrist.
