Reducing your screen time is one way to help with these symptoms and – hopefully – brighten your sclera. Other symptoms of CVS are blurred vision and headaches, which can occur as a result of severely dry eyes, exacerbating the redness. When looking at screens, you blink a lot less which can lead to dry eyes and the associated redness. In turn, avoiding caffeine and alcohol helps with better sleeping patterns and overall better-rested eyes.Ĭomputer Vision Syndrome (CVS) is a condition caused by high exposure to digital screens, either in the form of smartphones, televisions, or computer screens. Getting 7-8 hours of sleep each night helps your eyes rest and rehydrate overnight, combatting potential dry eye symptoms.

If you see someone with bloodshot eyes, chances are you’ll assume they’re tired. Sleeping is one of the main causes of red eyes, and this fact seems to be well-known. The sun can also cause bloodshot eyes and brown pigmentation spots on your sclera, so wearing UV protection sunglasses is an essential step you can take to avoid this. As well as changing the colour of your sclera, the sun exposure can change the eyeball’s natural curve, affecting your prescription and potentially causing astigmatism. Other symptoms of pterygium are itching and burning, and a foreign body sensation. It’s a condition called pterygium, triggered by UVB rays which come from the sun. High exposure to the sun can actually yellow the whites of your eyes. It also helps with your overall hydration, brightening the eyes. This helps to detoxify the liver, a part of the body which influences your scleral colour. Something that comes alongside drinking more water is cutting out – or reducing your intake of – caffeine and alcohol. Dehydrated eyes can also lead to dry eye disease which, in turn, promotes scleral redness due to the irritation. Not drinking enough water can also make your eyes appear duller as they rely on hydration to lubricate themselves, and to ensure that the eye’s blood vessels function properly. Leafy greens like kale, spinach and broccoli also contain vitamin A and beta carotene, encouraging blood flow to your eye and promoting blood vessel health – particularly ideal for red eyes! Vitamin C is known to prevent the build-up of foreign debris in your eyes. This is because they are rich in antioxidants and vitamins that promote eye health such as vitamins A and C. It is thought that eating yellow and orange fruits and vegetables prevents scleral redness. First up is a diet change, which is something that heavily impacts all aspects of our health. There are a number of methods that people employ to achieve whiter sclerae.

White sclerae, along with white teeth, clear skin and silky hair – to name but a few – are all seen as indications of health and beauty in today’s society.

They were also rated younger-looking than individuals with redder and yellower eyes. Numerous studies have shown that the whiter a person’s sclerae, the healthier and more attractive they are perceived to be.

Without the sclera being so visible, some of these health conditions may take much longer to uncover. Yellow-tinted sclerae can be the first sign that something is wrong with a person’s liver or pancreas function, and should be taken very seriously. Red sclerae can indicate dry eyes, abnormal blood vessels elsewhere in the body, or can suggest that someone has been crying – again highlighting the sclera’s key function in socialisation. Experts theorise that the visibility of humans’ sclerae (plural) is what elevated our presence as a social species.Īlong with its social communication benefits, the sclera is also a great indication of a person’s health, with different colours and visibility of blood vessels suggesting a range of health complications. Seeing the white of the eye allows you to tell where someone is looking, displaying emotions and encouraging better communication. Humans are actually the only primates to have a visible sclera which is thought to come hand in hand with our status as the most social beings. The sclera is the white part of your eye that you see surrounding the iris (the coloured section which houses your pupil).
