The eye floater appears as spots, threads, or cobweb-like shapes in the field of vision. These tiny clumps of gel or cells inside your eye’s vitreous humour become more common with age as this gel-like substance begins to liquefy and shrink. While medical treatments exist for severe cases, many seek natural solutions first. Research suggests certain eye supplements for floaters may help reduce their appearance or prevent new ones from forming by addressing underlying causes and supporting overall eye health.
Antioxidants and vision health
Antioxidants neutralise free radicals before they damage eye tissues. Several studies indicate that antioxidant supplements slow vision deterioration and help with floaters. Vitamins C and E work synergistically to protect against oxidative damage, with vitamin C found in high concentrations in the eye’s aqueous humour. Flavonoids like quercetin and rutin enhance the effectiveness of vitamin C and reduce inflammation, which can contribute to floater formation. These compounds strengthen blood vessels in the eyes and reduce the leakage of blood cells into the vitreous. The antioxidant anthocyanins found in bilberries and other dark berries have been studied to improve night vision. These compounds may help maintain vitreous viscosity and prevent collagen fragmentation that leads to floaters.
Essential vitamins to consider
Several specific nutrients show promise for supporting eye health and potentially reducing floaters:
- Vitamin C (500-1,000 mg daily) – Supports collagen production and acts as a powerful antioxidant
- Vitamin E (400 IU daily) – Protects cell membranes from oxidative damage
- Lutein and Zeaxanthin (10-20 mg daily) – Carotenoids that filter harmful blue light
- Omega-3 fatty acids (1,000-2,000 mg daily) – Reduce inflammation and support retinal health
- Vitamin B complex – Helps maintain proper nerve function in the eyes
- Zinc (25-40 mg daily) – Essential for transporting vitamin A from the liver to the retina
The AREDS2 formula, developed through extensive clinical research, combines many nutrients in specific ratios proven to support eye health. While not specifically tested for floaters, this combination addresses many underlying factors contributing to their formation and may help maintain vitreous health over time.
Natural sources vs. supplements
- Obtaining nutrients from food provides additional beneficial compounds that work synergistically with vitamins and minerals. Vegetables and fruits containing lutein and zeaxanthin. Citrus fruits, bell peppers, and berries provide vitamin C. Nuts and seeds supply vitamin E and omega-3 fatty acids.
- Supplements offer more concentrated doses that may be difficult to obtain through diet alone. They also provide consistent amounts of specific nutrients targeted for eye health. However, quality varies widely among supplement brands. Look for products tested by third-party organisations that verify content and purity. Always choose supplements free from unnecessary fillers, artificial colours, and potential allergens.
Hydration and eye health
Proper hydration can help maintain eye health and reduce floaters. The vitreous humour consists of 99% water, and dehydration can alter its consistency. Drinking adequate water helps maintain proper vitreous viscosity and may help reduce the perception of floaters. Cathechins in green tea protect against free radicals while enhancing hydration. Some research suggests caffeine may temporarily affect vitreous pressure, so balance caffeinated beverages with plenty of water. Certain herbal teas, like ginkgo biloba and bilberry, may provide additional benefits for eye circulation. Avoiding alcohol helps prevent dehydration, which can worsen floaters. Establishing consistent hydration habits supports overall eye health and complements the effects of nutritional supplements for maintaining vitreous health.
