Vision & Eye Health

Antioxidants for Eye Health


For Better Vision, Keep an Eye Out for Foods High in Zeaxanthin, Lutein, Lycopene, and Astaxanthin.

Like everything else with the human body, the eyes eventually degrade with age. If you were lucky enough to experience 20/20 vision in youth, eventually, you too will most likely need some form of corrective treatment whether glasses, contacts, or laser eye surgery.

The good news is that we can use food as preventative medicine.  There are dietary actions that you can take focusing on four distinct naturally occurring carotenoids found in foods in order to prevent the inevitable loss of vision. Small shifts in your diet can relate to you seeing your family members more clearly, reading those books you love so much, and driving with better confidence.

Four great dietary sources you can seek for help with vision are zeaxanthin, lutein, lycopene, and astaxanthin…the so called ‘macular carotenoids.’ Each can be found naturally and easily obtained through dietary means. Word of advice, these carotenoids are oxidized and become useless when exposed to air for long periods of time or when cooked at high temperatures. Always use fresh options either steamed or cooked at low temperature for best results.

Lutein and zeaxanthin are pigments predominantly found in the eye.  They are also the exact same pigments which are responsible for the yellow, orange and green colors in many fruits and vegetables. These pigments in the eye act as a filter for blue light, protecting the macular region against oxidation by light.  A healthy macula of the eye, protected against the insults of reactive oxygen species, helps to maintain clear, crisp vision.

  • Foods high in Zeaxanthin and Lutein include leafy greens like spinach, kale, collard greens, romaine lettuce, dandelion greens, and turnip greens. They are also high in corn, broccoli, bell peppers, zucchini, Brussels sprouts, oranges, apricots, pistachios, pumpkin, and egg yolks.
  • The highest concentration of Zeaxanthin and Lutein are found in medicinal flowers such as marigolds and the Garden nasturtium.

While lutein and zeaxanthin are a little less recognizable, another powerful compound found to aid vision is lycopene. Lycopene is one of the most powerful antioxidants currently known occurring in food, and has many more benefits to us than just aiding vision. Lycopene also helps prevent cancer, prostate issues, and heart disease.

  • Lycopene is found readily in tomatoes, carrots, bell peppers, watermelon, guava, papaya, asparagus, red cabbage, and many more fruits and vegetables.
  • A Helpful Hint: Lycopene is actually most concentrated in tomato paste, so make your favorite red sauce for eye health!

Tomatoes contain about 3mg of lycopene per 100 grams but, contrary to popular belief, they don’t pack the most punch when it comes to lycopene.

Guavas are not only delicious, they also contain an impressive amount of lycopene, with 100 grams of guava holding over 5mg of this potent antioxidant.

If you’re looking for help minimizing the effects of age-related vision loss, look no further than these three essential compounds: zeaxanthin, lycopene, and lutein.

Astaxanthin is special, very special. Astaxanthin is a naturally occurring carotenoid pigment found primarily in marine organisms such as salmon, trout, crab, shrimp, and lobster, providing a pink-red color. Among the commercially important microalgae, Haematococcus pluvialis is the richest source of natural astaxanthin which is considered as “super anti-oxidant.” Natural astaxanthin produced by H. pluvialis has significantly greater antioxidant capacity than the synthetic one. Studies have also shown that naturally fermented Astaxanthin may be even more powerful in its antioxidant potential for eye and vision health.

Aging, amongst other reasons, is a common cause puffy eyes. We know that certain things can help: reducing salt, improving allergies, relieving sinus congestion, drinking more water, getting more sleep, and avoiding fatigue and stress.

This is one remedy you can enjoy internally and see the benefits externally — green tea.

Green tea has been used by countries and civilizations around the world to help fight aging because of the powerful antioxidants it has. Green tea contains polyphenols called catechins, epicatechins and EGCG. EGCG is one of the most important ones. They’re polyphenols that have powerful antioxidant effects.

What makes this such a great solution is you can simply brew a strong cup of green tea and enjoy its benefits. Here’s how to do it:

Lutein For Improving Vision


Do you struggle with poor vision? Have you noticed your vision failing you? Are objects (either from a distance or very close up) becoming increasingly blurry in the bright of day or the darkness of night? If so, then you need to know about the two powerful antioxidants found in common foods that may help your vision health: Lutein and Zeaxanthin.

Science has shown that both lutein and zeaxanthin bio-accumulates in the eye, particularly in the retina. This is where images of objects hit and the ophthalmic nerve submits those signals to the occipital region of the brain where we become conscious of what we’re seeing. This is why these two antioxidants are particularly important for vision health.

Where to find lutein and zeaxanthin

Although lutein and zeaxanthin are responsible for bright colors of many fruits and vegetables, they’re actually found in greatest amounts in dark, leafy, green vegetables. Interestingly, the chlorophyll in dark, leafy, green vegetables masks the color of lutein and zeaxanthin pigments so the vegetables appear green in color.

  • Kale
  • Egg yolks
  • Parsley
  • Spinach
  • Broccoli
  • Peas
  • Paprika
  • Orange juice
  • Honeydew
  • Melon
  • Kiwis
  • Red peppers
  • Squash
  • Grapes

How to include lutein and zeaxanthin in your daily diet

You can have a couple of poached eggs on a bed of lightly steamed kale, with diced red peppers and a sprinkling of paprika powder. As a side, have some honeydew melon and kiwis to start your day powerfully. It’s not too hard to start every day with breakfast foods that help improve your vision health!


vision-20 supplement by zenith labsHint: Fats actually improve the absorption of lutein and zeaxanthin so including fats into your diet may help the bioavailability of lutein and zeaxanthin. Adding some butter or coconut oil with your cooked greens or fresh salads is a great idea.

The team at Zenith Labs have created a supplement called Vision 20, which aims to improve vision health. Your diet should always come first, but supplements such as Vision 20 can give you a real boost. Check it out and let us know what you think!

The Top 6 Things You Should Never Do to Your Eyes

Take just a moment to think about what life would be like without vision. Unless you were born blind, you have no concept of what it means to not be able to see, but if you were to suddenly lose your vision, you would very quickly learn just how much relied on it. Because your vision is so essential, it pays to take good care of your eyes. Unfortunately, you are probably making some simple mistakes on a daily basis that could be dangerous for your eyes.

Maintaining healthy eyes and proper vision requires more than just an annual visit to the eye doctor. First and foremost, you need to understand how your daily habits have the potential to affect your eyes and thus your vision. Next, you should educate yourself about the most common eye problems, so you can learn how to avoid them. That’s exactly what we’re going to cover in this article, so keep reading!

Never Do These 6 Things to Your Eyes

When it comes to keeping your eyes healthy, it’s largely a matter of common sense. You should never put something in your eye that you aren’t absolutely sure is safe, and you should take basic precautions regarding exposure to bright light. In addition to these basics, never do the following 6 things:

  1. Never sleep in contacts. Contact lenses physically cover the surface of the eye which can block oxygen from reaching the corneas – this can result in infection or corneal ulcers. Even the “overnight wear” contacts can contribute to this problem so always remove your contact lenses for anything longer than a cat nap.
  2. Never wear makeup to bed. Not only is wearing your makeup to bed bad for your skin, but it can clog the glands around your eyes and increase the risk of skin irritation. Always include makeup removal in your nightly skincare routine.
  3. Never apply liner to your waterline. Applying liner to your waterline might complete your look, but it can also mix with your tears and coat your contact lenses with particles that attract bacteria. Stay safe by only applying liner to your outer lash line.
  4. Never use expired eye care products. Eye care products have an expiration date for a reason – not only are they less effective past that date, but they could actually harm your eyes. Always check products like eye drops, contact solution, and even the contacts themselves to make sure they are fresh.
  5. Never misuse eye drops. While eye drops may help to relieve problems like redness in the short term, using them more often or for longer than recommended can actually make the problem worse. For example, redness-reducing eye drops work by shrinking the blood vessels in the eye, but that can lead to circulation problems if you use them too much.
  6. Never skip your annual eye exam. Your annual eye exam is your best protection against serious and chronic eye problems – problems that can occur within the structure of the eye where you can’t see them. An annual eye exam does more than just check your vision – it also checks for problems like glaucoma and macular degeneration.

In addition to avoiding the six things listed above, don’t make the mistake of ditching your sunglasses during the winter. Though you may be tempted to soak up every ray of sun you can on a bright wintery day, you still need to protect your eyes from UV rays – the sun can still damage your eyes even in the winter. Wearing sunglasses does more than just make it easier to see in bright conditions – they also help prevent corneal burns, cataracts, skin cancer on the eyelids, and even macular degeneration. Just make sure that the shades you pick block at least 99% of both UVA and UVB rays.

What Are the Most Common Eye Problems?

Now that you know the basics about what not to do to your eyes, you should take the time to learn some healthy habits for protecting your eyes and that starts with learning about some of the most common eye problems. The more you know about common eye issues, the better you will be able to protect yourself from them or, at the very least, identify the symptoms early on so you can seek treatment. These are the five most common eye problems:

  1. Cataracts – A cataract is a clouding of the lens that can obstruct your vision. In most cases, cataracts are related to aging, but other factors such as smoking and diabetes can contribute as well. Symptoms of cataracts may include blurred vision, faded color vision, glare, poor night vision, and double vision. Unfortunately, cataracts do not go away, and surgery may be required if they cause vision loss sufficient to impact your daily activity.
  2. Refractive Errors – Vision is the result of light passing through the structures of the eye and being refracted, or bent, to form images. When that refraction becomes skewed, it results in vision problems such as nearsightedness, farsightedness, and astigmatism. These problems are best treated with corrective lenses.
  3. Glaucoma – The term glaucoma refers to a collection of diseases that damage the optic nerve in the eye, typically the result of fluid accumulation and rising pressure inside the eye. Unfortunately, symptoms of glaucoma typically don’t develop until the problem becomes advanced and vision loss due to glaucoma cannot be restored. Increased intraocular pressure can be corrected with medicated eye drops, however, to slow or prevent progression.
  4. Diabetic Retinopathy – A complication of poorly managed diabetes, diabetic retinopathy is caused by damage to the blood vessels in the retina, the light-sensitive tissue in the eye. In the early stages, this condition causes no or only mild vision problems, but it can progress to total blindness. Controlling blood sugar is the best way to prevent this problem.
  5. Macular Degeneration – The leading cause of vision loss, macular degeneration affects more people than cataracts and glaucoma combined, and it is an incurable eye disease. Macular degeneration is caused by deterioration in the central part of the retina, the macula, and there are several different types of the disease. Risk factors for macular degeneration include genetics, age, race, and smoking habits.

Because you use your eyes all day every day, you may not notice when small or subtle changes occur. As soon as you become aware that something has changed, you should contact your doctor. Catching eye problems in the early stages is essential for treatment, especially for diseases that can lead to a partial or total loss of vision. Even if it turns out to be nothing, it is always better to be safe than sorry.

There are seven foods that will improve your eyesight, as long as you eat them every day. They are high in certain micro-nutrients such as lutein, zeaxanthin, vitamin C, polyphenols, proanthocyanadins, and vitamin A, which can make a powerful difference in your vision going forward.

1. Foods containing Lutein & Zeaxanthin

  • Eat foods like: Broccoli, cauliflower, kale, bok choy, spinach, squash

Firstly, eat foods high in lutein and zeaxanthin. These are antioxidants that concentrate in your eyes. In fact, they concentrate in the back of your eyes where the retina is. They help with daytime vision, blurriness, night-time vision and floaters. Foods that are high in both lutein and zeaxanthin include the brassica vegetables (e.g.) broccoli, cauliflower, bok choy, and kale. Other foods high in these nutrients include spinach, squash (any kind), corn, peas, and eggs. Try to incorporate these foods into your daily diet.

2. Food containing Vitamin A

  • Eat foods like: Squash, spinach, bilberry and rose hip tea

Another nutrient is vitamin A. Squash and spinach have particularly high contents of vitamin A so try to get those in your diet. Something else you can actually try is a combination tea of bilberry and rose hips. It’s extremely high in vitamin C, polyphenols, and proanthocyanins, that feed the eyeballs and retina. Go to your local health foods store, get a little bag of bilberry and a little bag of rose hips, and you can easily brew a tea.

You can add some honey to it for flavor if needed. But this is packed full of proanthocyanins that basically go to your eye as antioxidants.
