Why Eggs Are a Superfood For Your Eyes

Eggs have long been lauded as a healthy and affordable source of protein. Whether scrambled, boiled, or poached, eggs have found their way onto breakfast tables worldwide. Now, recent studies have shown that eggs may be more beneficial than we previously thought. 

Not only are they good for your body, but they may also help maintain healthy eyesight. So, if you’re looking to boost your eye health, keep on reading to find out the truth about eggs and your eyes!

The Nutritional Value of Eggs

Eggs are not only delicious, but they also pack a powerful nutritional punch. In fact, one large egg contains 6 grams of protein, as well as essential vitamins and minerals such as vitamin A, iron, and zinc. 

But what makes eggs so good for our eyes? Let’s take a closer look at the nutrients and health benefits of eggs for our vision.

Lutein and Zeaxanthin

Eggs are a rich source of both lutein and zeaxanthin, two antioxidants known for their role in maintaining the health of your eyes.

These carotenoids are found in the retina of our eyes, where they help protect against harmful blue light from computer screens and UV rays, and reduce the risk of age-related macular degeneration (AMD) and cataracts. 

In fact, a study published in the American Journal of Clinical Nutrition found that participants who consumed just one egg per day had significantly higher levels of lutein and zeaxanthin in their blood compared to those who did not eat eggs. 

Vitamin A

Vitamin A is an essential nutrient for maintaining healthy eyesight. It helps to keep night vision sharp and can also prevent dry eyes, which can lead to discomfort and irritation.

Eggs are a great source of vitamin A, with one large egg containing 6% of the recommended daily intake. 

Vitamin E​

Vitamin E is another antioxidant found in eggs that can benefit our eyes. This beneficial vitamin helps to protect against age-related eye disease and vision problems, and may even slow the progression of cataracts. 

One large egg contains about 7% of the recommended daily intake of vitamin E, making it a valuable source for maintaining healthy eyes.

Omega-3 Fatty Acids

Omega-3 fatty acids are not naturally produced by the body, which means we must get them from our diet. These essential fatty acids are crucial for maintaining healthy eyes and have been linked to a reduced risk of conditions such as dry eye syndrome and AMD.

Eggs from chickens that are fed a diet rich in omega-3s may contain higher levels of these beneficial fatty acids. So, it’s worth checking the label when purchasing eggs to ensure you’re getting the most out of their omega-3 content.


Additionally, the protein in eggs is not only beneficial for maintaining overall health, but it is also important for eye health. The protein in eggs contains amino acids that are essential for producing the proteins used to make and repair eye tissue.

Eye tissue, including the cornea and lens, is constantly being replaced and repaired in order to maintain sharp vision. Therefore, getting enough protein in your diet is crucial for keeping your eyes functioning properly.

Types of Eggs

Not all eggs are equal in terms of nutrients availability. For instance, free-range eggs may have higher amounts of lutein and zeaxanthin because the hens get to eat more greens, which boost these nutrients concentration in their eggs. 

In contrast, eggs from factory-fed hens may have lower amounts of essential nutrients. Hence, it is recommended to go for free-range, organic, or pasture-raised eggs since they offer a higher nutrient profile.

Besides chicken eggs, other types of eggs such as quail, duck, and goose eggs also contain essential nutrients that can benefit our eyes. However, they may also contain higher levels of cholesterol, so it’s important to consume them in moderation.

Also, when it comes to cooking eggs, the method can also impact the nutrient content. For example, boiled eggs may retain more nutrients compared to fried or scrambled eggs, while poached eggs may have a similar nutrient profile to boiled eggs.

Common Eyesight Problems and How Eggs Can Help

Now that we know about the nutrients in eggs, let’s explore how they can benefit our eyes and prevent vision problems.

Age-Related Macular Degeneration (AMD)

As mentioned earlier, lutein and zeaxanthin are crucial antioxidants for maintaining healthy eyes. Studies have shown that these two carotenoids may reduce the risk of macular degeneration, which is the leading cause of vision loss in people over 50.

Including eggs in your diet can boost your lutein and zeaxanthin levels and potentially reduce the risk of AMD. Additionally, eggs also contain other nutrients that may aid in preventing this early age-related condition.

Dry Eye Syndrome

Dry eye syndrome is a common condition that occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. This can lead to discomfort, irritation, and even impact vision.

Studies have shown that omega-3 fatty acids may help improve dry eye symptoms by reducing inflammation and increasing tear production.

 As previously mentioned, eggs are a good source of these beneficial fatty acids, making them a valuable addition to the diet for those suffering from dry eyes.


Cataracts occur when the lens of the eye becomes cloudy, leading to blurry vision and eventually blindness if left untreated. While cataract surgery is a common treatment option, prevention through diet is also essential.

Studies have shown that lutein and zeaxanthin may play a role in preventing the risk of cataracts. Additionally, vitamin E and omega-3 fatty acids found in eggs may also offer protection against this condition.
