Photo of author

Have you ever wondered how Vitamin C affects the risk of getting Cataracts? It’s a common question for people dealing with Cataracts and seeking home remedies.

Cataracts are an eye condition in which the eye’s natural lens is clouded and are a common cause of vision issues and blindness worldwide.

Vitamin C lowers the risk of Cataracts by acting as an antioxidant and fighting off oxidative stress (primarily responsible for Cataracts).

This article will explore the relationship between Vitamin C and risk of Cataracts, foods rich in Vitamin C, and how Vitamin C supplements increase the risk of Cataracts.

Vitamin C and Risk of Cataracts

Vitamin C (also known as ascorbic acid) is a water-soluble vitamin present in various fruits and vegetables.

It is beneficial for eye health as it reduces eye pressure and helps fight against different types of Cataract formation

Vitamin C is well acknowledged for its antioxidant properties and protects the body against damage caused by free radicals.

Free radicals are unstable molecules associated with various diseases, including Cataracts.

Research has suggested that Vitamin C may contribute to ocular health by preventing oxidative damage to the lens in the eye.

The lens is a transparent structure that focuses light onto the retina. It is vulnerable to oxidative stress and can lead to Cataract formation.

Vitamin C’s ability to neutralize free radicals potentially reduces the risk of Cataracts.

Let’s discuss these foods and fruits that can help alleviate Cataract symptoms in detail.

Citrus fruits: Oranges, lemons, and grapefruits are renowned for their Vitamin C content. A daily dose of citrus fruits can contribute to overall eye health.

Berries: Strawberries, blueberries, and raspberries are delicious and packed with antioxidants, including Vitamin C. Incorporating this fruit into your daily diet could be a flavorful way to support your eyes.

Kiwi: It has a notable Vitamin C content and provides antioxidant support to the eye, which potentially aids in reducing Cataract risk.

Bell peppers: All types of bell peppers (red, yellow, and green) are sources of Vitamin C and help decrease the risk of Cataracts.

Broccoli: This vegetable is a powerhouse of nutrition and a good source of Vitamin C.

Guava: This tropical fruit boasts a higher Vitamin C content than many citrus fruits. It is a nutrient-rich option that may reduce the risk of Cataracts.

Incorporating these Vitamin C-rich foods into your diet can be an efficient home remedy to support your eye’s optimal health.

Vitamin C is not the sole solution for Cataracts. It should be used as a supplementary measure along with medication. Consult with a doctor for a proper diagnosis and treatment plan.

Vitamin C is essential in protecting eye health and reducing the risk of Cataracts because of its antioxidant properties and ability to protect the eye against free radicals.

However, some recent research has raised questions about the impact of Vitamin C supplements on Cataract risk.

Research suggests that excessive Vitamin C intake through supplements might increase the risk of developing Cataracts, especially in women above the age of sixty five.

The body has a delicate balance, and excessive amounts of vitamins can disrupt this dosage.

In the case of Vitamin C supplementation, the risk lies in the dosage.

High dosage, often exceeding the recommended daily intake, may contribute to adverse effects.

The recommended daily dosage of Vitamin C for adult males is 90mg/per day, and for adult females is 75mg/per day.


Vitamin C and risk of Cataract is related to each other as Vitamin C is key in reducing the risk of  Cataracts and maintaining overall eye health.

Choosing a balanced diet abundant in Vitamin C-rich foods provides a natural and balanced approach to support eye health.

Foods and fruits like citrus fruits, bell peppers, berries, kiwi, broccoli, and guava offer Vitamin C in ample quantity and can be incorporated into your diet easily.

While the antioxidant properties of Vitamin C offer protection against oxidative stress, excessive 

Vitamin C supplement intake might increase the chances of developing Cataracts.

Therefore, you can eat foods rich in Vitamin C to reduce your risk of Cataracts, but taking it in moderation is essential

Consult with a healthcare professional before following any home remedy or treatment plan is important.
