The white of your eyes is called the sclera. You can get a lot of information about a person’s health from the whites of their eyes – fatigue, allergies, liver problems, etc. In fact, looking after the health of your body is the best way to look after the colour of the whites of your eyes. Here are a few recommendations…
1. Use eye drops
There are different types of eye drops. Classic saline drops bought in the pharmacy aim to reduce redness and humidify the eyes, as well as neutralising certain irritants or better irrigating the eyes. Generally, two to three drops per eye is enough. There are also more viscous drops (Japanese eye drops) which have refreshing properties, if you suffer from burning or redness in the eyes. These can be hard to find (try health food shops or international pharmacies). Their special texture may not suit you in the beginning as they are “harder”. The blue drops (by Innoxa) firstly soothe the eyes from burning and redness. Once you put them in your eyes, the liquid covers the cornea with a very fine bluish film, which neutralises the yellowish or reddish colour of the sclera.
2. Eat plenty of fruit and vegetables
Certain fruits and vegetables such as lemons, oranges, pumpkins or carrots, are full of vitamins and antioxidants, which maintain the white colour in the eyes. The same goes for certain green vegetables (cabbage, spinach) and dried fruits/nuts which contain minerals (almonds, walnuts, peanuts, etc.). All of these fruits and vegetables will promote liver detox, which will help the liver better assimilate vitamins and other nutrients. When your liver is in good health, it can be seen in your eyes, which will be brighter and clearer.
3. Limit your consumption of refined sugars and carbohydrates
Also in the interest of detoxifying your liver, it is best to avoid consuming too much refined sugar and carbohydrates (white bread, pasta, salt, butter, etc.). It is not a question of cutting them out completely, but simply reducing the quantities of these types of foods.
4. Boost your intake of vitamin A
Your eyes need plenty of vitamin A in order to stay in good health. It is thus recommended that you eat foods that are rich in vitamin A, such as carrots and sweet potatoes, among others. You could even add to this consumption with vitamin A food supplements.
5. Sleep for 7 to 8 hours a night
We know it’s obvious, but a good night’s sleep will do your eyes the world of good. Getting enough sleep (but not too much ) allows the body to recover and gives your eyes the chance to retrieve their natural whiteness. Make sure to respect your own sleep cycles, and not to spend too much time in front of screens before going to sleep.
6. Drink plenty of water
For white, bright eyes, drinking water is essential. Your eyes need permanent hydration. When your body is properly hydrated, your eyes will be better irrigated and thus less red/yellow and swollen. The ideal is to drink between 1.5 and 2 litres of non-sparkling water per day (8 to 10 glasses).
7. Reduce your consumption of coffee and alcohol
Both of these substances dehydrate the body and contribute to swelling and discoloration of the whites of the eyes. Alcohol and coffee also have an obvious effect on your sleep. In particular, they can reduce the number of hours of sleep you get.
8. Avoid smoking
Smoking cigarettes or other substances can irritate your eyes and make them red. Avoiding smoking allows for better hydration of the eyes and a return to their normal white colour. Like with other irritants such as dust and pollen, it is possible to reduce them using a home air purifier, for example.
9. Wear sunglasses
Be aware that UVA and UVB rays are likely to damage your eyes over time. High levels of sun exposure promote yellowing of the sclera. To avoid this, you simply need to wear sunglasses when you are outside, when the natural light reaches a certain level (even on cloudy days – the clouds won’t protect your eyes from sun damage). It is best to buy good quality sunglasses which will best protect you from the sun’s rays.
