Supplements for Eye Health: How to Naturally Support Your Vision

Staring at screens all day. Squinting through digital meetings. Rubbing tired eyes after hours of scrolling or reading.
Sound familiar?

Whether you're in your 30s, 40s, or pushing 50, chances are you’ve started to notice that your eyes feel more tired than they used to. And while it's easy to blame screen time (which is a big part of the problem), supporting your eye health takes more than adjusting your monitor brightness.

Let’s look at simple, science-backed ways to protect your eyesight—plus one green superfood that might surprise you.

 

How Food—and Superfoods—Support Eye Health

In a 2008 study published in the American Journal of Ophthalmology, researchers found that women who ate leafy greens like kale and collards just once a month were 69% less likely to develop serious eye problems later in life.

Yes, just once a month.

Now imagine what you could do for your vision by fueling your body with one of the greenest, most nutrient-dense foods on Earth—chlorella—every single day.

 

Why Chlorella Deserves a Spot in Your Eye Health Routine

Chlorella is a freshwater algae often called The King of Superfoods. It's packed with vitamins, minerals, antioxidants, and more chlorophyll than almost any plant food. Just one serving delivers the chlorophyll equivalent of 2–2.5 cups of spinach or kale.

But more importantly for your eyes, chlorella contains carotenoids—special plant pigments proven to support vision and protect eye tissues from damage.

Here’s how these carotenoids work for your eye health:

Lutein

Lutein is one of the most essential nutrients for eye health. Eye doctors can actually measure the amount of lutein in your retina to assess your visual performance. While one serving of Sun Chlorella Tablets or Sun Chlorella Powder won’t give you the full daily dose used in clinical studies, it still provides a solid 3 to 6 mg per serving—a strong foundation.

Beta-Carotene (Vitamin A Precursor)

Vitamin A was first recognized because of its essential role in maintaining healthy vision. Chlorella contains natural beta-carotene, which your body can convert into vitamin A. One serving of Sun Chlorella Tablets provides 5% of your daily vitamin A needs.

But here's the key: carotenoids compete for absorption in the body. Too much beta-carotene, for example, can reduce how much lutein your body uses. That’s where chlorella shines—its natural balance of carotenoids means your body can absorb them in optimal amounts, the way nature intended.

And unlike synthetic sources, the lutein in chlorella is in the same natural form used in the most respected studies on supplements for eye health.

Exercise: An Unexpected Boost for Eye Health

You already know exercise is great for your body—but what about your eyes?

Preliminary research suggests that working out may boost a growth hormone in the retina, helping your eyes defend against UV damage and improving how they react to light. So, the next time you hit the gym or go for a walk, know you’re also giving your eyes a little extra love.

The 20-20-20 Rule: Your Best Defense Against Screen Fatigue

If your job or lifestyle has you glued to screens, you’re not alone. But all that screen time can dry out your eyes and strain your focus.

• Try the 20-20-20 rule:
  Every 20 minutes, take 20 seconds to look at something 20 feet away (6 meters).

It’s a simple habit that gives your eyes a chance to rest and reset—especially important if you're starting to feel the effects of digital eye strain.

Everyday Tips to Support Your Eyes Naturally

Keeping your vision sharp isn't just about genetics—it's about daily habits. Here’s how to protect your eyes long term:

• Eat eye-friendly nutrients like lutein, beta-carotene, and vitamin A
• Exercise regularly
• Get outdoors for natural light exposure
• Rest your eyes throughout the day
• Use high-quality supplements for eye health
