Glaucoma Diet: What to Eat & What to Avoid by Steve Seah your Singapore Eye Specialist 




Glaucoma is one of the leading causes of progressive and permanent vision loss in the world. Characterized by a build-up of eye pressure that damages the optic nerve, it is known as the silent thief of sight because it slowly causes blindness without showing any symptoms until its later stages. It’s important to note that treatment of glaucoma only halts the progression of vision loss. The condition itself is incurable, and damage done pre-treatment is irreparable.

In this case, the age-old adage, “Prevention is better than cure.” applies. There are plenty of ways by which you can reduce your risk of developing glaucoma, from engaging in certain exercises to moderating the food you eat. Here’s a list of what and what not to eat to promote eye health and prevent the development of any eye disease, glaucoma or not:

What to Eat
If you want perfectly good eyesight, don’t forget your fruits and vegetables. Dark, leafy greens, yellows and oranges are especially rich in carotenoids, zeaxanthin and the “eye vitamin” lutein, which not only promote vision health, but protect against other illnesses as well. These include spinach, kale, cabbage, collard greens, broccoli, carrot, Brussels sprout, sweet potatoes, beans, squash, mango and peach.

A variety of food is also a great source of vitamins beneficial for eye health, which are:
·         Vitamin A: carrots, egg yolks, sweet potatoes, milk, liver, mangos
·         Vitamin C: citrus fruits, leafy greens, tomatoes, broccoli, potatoes, green peppers
·         Vitamin D: fish liver oil, salmon, mackerel, tuna, dairy products
·         Vitamin E: eggs, cereals, whole grains, fruits, leafy vegetables, nuts

Certain eye conditions like cataracts and vision impairments have been linked to zinc deficiency. Aside from supplements, you can up your daily zinc intake by consuming red meat, poultry, beans, seafood, whole grains, cereals and dairy products.

What to Avoid
It’s not enough to just eat eye-friendly food. You should also know which ones to avoid or consume in moderation.

Caffeine, for instance, is known for its antioxidant properties. However, drinking too much can increase intraocular pressure and decrease blood flow to the retina. Caffeine-rich products include coffee, tea, chocolate and soft drinks. Instead of these, you may want to consider healthier alternatives like decaf coffee, herbal tea, lemon water or hot water.

Drinking a large amount of fluid in a short period of time is also harmful for your eyes. Similar to excessive caffeine intake, doing so also increases intraocular pressure. To prevent this, you should just control your fluid intake frequency, choosing to sip small amounts several times throughout the day, instead of drinking a large volume at once.
