EAT RIGHT, SEE RIGHT- HOW DIET AFFECTS YOUR EYE HEALTH

The adage 'you are what you eat' extends its influence to every facet of human health, including our vision. A balanced, nutrient-rich diet does more than just keep our bodies healthy; it also contributes significantly to eye health.
From combating Macular Degeneration to affecting Glaucoma and improving overall sight, the impact of diet and nutrition on our vision cannot be overstated. In this comprehensive article, we will explore how various elements of diet and nutrition affect eye health.

The health and vitality of our eyes are significantly influenced by the various nutrients we consume. Among these, vitamins A, C, E, and B complex are vital. Vitamin A, for example, supports the functioning of the retina. At the same time, Vitamin C, an essential antioxidant, helps fight oxidative stress, which can damage our eyes. Vitamin E, on the other hand, plays a pivotal role in maintaining cell health, including those of our eyes.

Vitamin A, one of the most vital nutrients for eye health, contributes to maintaining the cornea's health, the clear front surface of the eye. Additionally, it supports the functioning of the retina and helps prevent conditions such as age-related macular degeneration and cataracts. Carrots, sweet potatoes, spinach, and kale are excellent sources of vitamin A.

Given the plentiful presence of Vitamin A in everyday foods like carrots, sweet potatoes, spinach, and kale, most balanced diets should provide an adequate amount, ELIMINATING the need for additional Vitamin A supplementation in most cases.

Omega-3 fatty acids are crucial for retinal health, which converts light into neural signals for our brain, making a diet rich in Omega-3 essential for preserving sight. They have potent anti-inflammatory properties, helpful in managing Dry Eye Disease symptoms, leading to discomfort, visual disturbance, and tear film instability.

These fatty acids, particularly DHA (Docosahexaenoic Acid) and EPA (Eicosapentaenoic Acid) enhance retinal function, responsible for light detection and vision. They improve the tear film's lipid layer, preventing tear fluid evaporation, thus reducing dry eye disease discomfort.

Common sources of Omega-3 fatty acids, including DHA and EPA, are fatty fish like salmon, mackerel, and tuna. For those following a vegetarian or vegan diet, chia seeds and flaxseeds also provide a substantial amount of these essential nutrients. Including these in your diet supports overall eye health.

Maqui berries contain a higher concentration of omega oils than bilberries.Omega oils are essential fatty acids critical for overall health and well-being. They support healthy cell membranes, improve brain function, and reduce inflammation.

Maqui berries also contain a unique compound called delphinidin that may benefit your eye health. In published studies, researchers found that delphinidin improved the function of cells lining the blood vessels in the eyes, reducing inflammation and improving circulation. This may benefit eye diseases such as macular degeneration and cataracts, which are associated with inflammation and poor eye circulation.

Sugar, in moderation, is a necessary part of our diet, supplying us with quick energy and playing a vital role in various bodily functions. However, when consumed excessively, sugar can lead to severe health complications. Overconsumption of sugar contributes significantly to the rise of obesity and diabetes. These two conditions are risk factors for various eye health issues.

When our bodies have too much sugar, it can lead to high blood sugar levels, a condition known as hyperglycemia. This can cause considerable damage to the tiny blood vessels in our eyes. Over time, this damage can result in serious eye conditions. One is diabetic retinopathy, a diabetes complication affecting the eyes, leading to vision impairment or blindness. High blood sugar levels can also increase the risk of Glaucoma, a group of eye conditions that damage the optic nerve, often due to abnormally high pressure in the eye.

To maintain good eye health, monitoring and limiting sugar intake is crucial. This can be achieved through a balanced diet, regular physical activity, and routine check-ups to monitor blood sugar levels. Consuming fruits, vegetables, lean proteins, and whole grains while avoiding sugary beverages and processed foods can contribute significantly to optimal eye health.

Dehydration, a condition characterised by the body's lack of sufficient water, can surprisingly impact our eye health. It can lead to symptoms such as eye strain, which manifests as discomfort or fatigue in the eyes. Strain often arises when the eyes are not adequately lubricated, possibly when the body is dehydrated.

Further, dehydration can lead to dry eyes and insufficient tear production. Tears are essential for maintaining the eye's health and providing clear vision. The body may not produce enough tears when dehydrated, leading to Dry Eye Symptoms such as redness, stinging, and a gritty sensation.

Our test (click below) is based on the clinically-proven OSDI (Ocular Surface Disease Index) and checks how dry your eyes are - a crucial indicator of underlying health issues.

Glaucoma, a condition characterised by damage to the optic nerve, often due to high intraocular pressure, can lead to vision loss if not managed effectively. While no specific diet can cure Glaucoma, nutrition plays a pivotal role in managing the disease and maintaining overall eye health.

A balanced diet is essential. Consuming various fruits and vegetables can provide the necessary vitamins and minerals that can help protect the eyes against damage. These include antioxidants like vitamins A, C, and E and nutrients like lutein and Zeaxanthin, which are especially beneficial for eye health.

Lean proteins, such as chicken, turkey, fish, and legumes, can help maintain the body's tissue, including the eyes. Additionally, healthy fats, including Omega-3 fatty acids in fatty fish, flaxseeds, and chia seeds, contribute significantly to retinal health and can help alleviate glaucoma symptoms.

In conjunction with regular eye check-ups and appropriate medical treatment, maintaining a diet rich in these nutrients can help slow down the progression of Glaucoma and contribute to the overall well-being of the eyes. Staying hydrated, limiting caffeine intake, and reducing the consumption of foods high in sodium can further support eye health.

Achieving optimal eye health isn't only about eating the right foods but also limiting those that could be harmful. Processed foods, often high in unhealthy fats and sugars, should be consumed in moderation. They are known contributors to obesity and diabetes, conditions associated with various eye health issues like Glaucoma and diabetic retinopathy. Consuming too much salt can also lead to hypertension, impacting eye health.

Similarly, alcohol, in excess, can lead to vision problems. Lastly, foods with trans and saturated fats, often found in fried and baked goods, can adversely affect your eye health, leading to conditions like macular degeneration.

Age-related Macular Degeneration (AMD), a common eye condition that affects the macula - the centre of the retina responsible for clear vision - is a leading cause of vision loss in older adults. A nutrient-rich diet is vital to managing AMD's progression, packed with vitamins A, C, E, zinc, and antioxidants such as Lutein and Zeaxanthin. These elements work in unison to shield the eyes from damaging oxidative stress, a primary factor in AMD.

The Age-Related Eye Disease Study 2 (AREDS2), a major clinical trial, showcased the significance of these nutrients, affirming that a supplement containing these could decelerate AMD in those predisposed to its advanced stages. Foods rich in Lutein and Zeaxanthin - mainly leafy greens and corn - also play a crucial role in protecting against harmful blue light and oxidative harm. Hence, a diet filled with these nutrient-dense foods is a strategic approach to maintaining eye health and slowing AMD's progression.

Excessive alcohol consumption can lead to short-term and more permanent long-term issues. We have a more detailed guide on alcohol and its effects on your eyes - link below.

Short-term issues include blurry vision, dry eyes, twitching eyelids, bags under the eyes, and sensitivity to light.

Longer-term issues include cataracts, age-related macular degeneration, optic neuropathy, persistent dry eyes, and colour vision changes.

Antioxidants play a pivotal role in safeguarding our eyes from harmful free radicals - unstable molecules that can cause significant damage to our cells. Among the most potent antioxidants are Lutein, Zeaxanthin, and vitamins C and E. They provide a protective shield against the oxidative damage these free radicals can inflict on our eyes, damage which could lead to serious eye conditions like Age-related Macular Degeneration (AMD) and cataracts.

Lutein and Zeaxanthin, found in high concentrations in the eye's macula, are known to filter harmful blue light and ward off oxidative damage. Green leafy vegetables like spinach, kale, and eggs are excellent sources of these antioxidants.

Vitamins C and E, on the other hand, play an essential role in maintaining the health of your eyes' tissues and cells. Citrus fruits such as oranges, lemons, and grapefruits are rich in vitamin C. At the same time, nuts, seeds, and leafy greens are good sources of vitamin E. Berries, too, are packed with these antioxidants.

In conclusion, while genetics and age play significant roles in our eye health, a balanced diet rich in essential vitamins, minerals, and antioxidants can go a long way in maintaining good vision and slowing the progression of various eye conditions.

Like the rest of your body, your eyes will significantly benefit from a lifestyle centred around whole foods, regular exercise, good hydration, and controlled intake of harmful substances like sugar and alcohol.
