Why Eye Drops Aren’t Fixing This
You know the routine.
By mid-afternoon your eyes feel heavy, dry, gritty.
You reach for eye drops. They help for twenty minutes. Then it’s back.
Eye drops add moisture to the surface. That’s all.
They can’t reach the muscles inside your eye that fatigue
from hours of close-range screen focus.
The problem isn’t on the surface of your eye. It’s inside it.
In Japan, this was recognised twenty years ago.
Millions take a daily antioxidant called astaxanthin —
a red pigment from microalgae that deposits directly in eye tissue.
Multiple clinical trials have studied it specifically in screen users.
The results are worth your attention.
5 Reasons This Is Different From Anything In Your Eye Care Routine
Clinically studied in screen users — results in 4 weeks.
That’s the result from a placebo-controlled trial of 82 heavy computer users who took astaxanthin for 4 weeks. Their eyes’ ability to refocus — the exact function screens exhaust — measurably improved.
A separate trial confirmed the pattern: focusing power improved significantly in the astaxanthin group. Biosphere delivers 12mg daily — above the doses used in every published study. Not a token amount. A therapeutic dose.

6,000× more powerful than vitamin C.
ANTIOXIDANT POTENCY INDEX
Relative free-medical
The most powerful antioxidant ever measured
Based on published antioxidant potency measurements in peer-reviewed research.
Published research measures astaxanthin’s free-radical neutralising power at 6,000 times vitamin C.
Peer-reviewed antioxidant potency data, not marketing.
Your eyes generate more oxidative stress per hour of screen time than almost any other organ.
Astaxanthin is the single most powerful antioxidant ever measured — and it has a specific affinity for eye tissue.

It targets the tired-focus feeling — and works in weeks, not months.
Astaxanthin deposits at the front of the eye, in the muscle that controls focus. This is the muscle screens exhaust. Lutein and zeaxanthin work differently — they accumulate at the back of the eye and take 6–9 months to build up. Astaxanthin showed clinical results in 4 weeks.
They complement each other. But if your main problem is screen fatigue, dry eyes, and end-of-day blur, astaxanthin targets the right mechanism.
Your body actually absorbs it
Most astaxanthin supplements waste your money. The ingredient is fat-soluble — deliver it alone and most passes through unused. Every Biosphere softgel includes a specialised absorption complex with olive oil, shown to enhance uptake of fat-soluble antioxidants by up to 12× compared to standard delivery.
And while your eyes get the primary benefit, published research shows astaxanthin also supports skin hydration, joint comfort, and cardiovascular health. Eyes first. Skin and joints follow.
If it doesn’t work, you don’t pay
No fine print. No hoops. Take it for two months.
If your eyes don’t feel different, we refund every cent.

Frequently Asked Questions
-
Clinical studies showed significant improvement in eye strain and focusing ability within 4 weeks. Some customers report less dryness in the first 1–2 weeks.
-
60-day money-back guarantee. Email us for a full refund. No questions, no hassle.
-
Clinical studies used 4–9mg. At two softgels daily, you’re getting 12mg — above every published study dose. More isn’t always better, but being above the therapeutic threshold matters.
-
Different target. Lutein accumulates in the macula (back of the eye) over 6–9 months. Astaxanthin deposits at the front of the eye where focus is controlled, and showed results in 4 weeks. They complement each other.
-
A naturally occurring antioxidant from microalgae — it’s what gives salmon their pink colour. Published research ranks it among the most powerful antioxidants ever measured.
-
Most Kiwis haven’t — yet. Astaxanthin has been mainstream across Asia for decades. Japan alone accounts for 25% of the global market. It’s newer to NZ but growing fast.
-
Yes. Astaxanthin is well tolerated and safe to combine with most supplements. If you’re on blood-thinning medication, check with your doctor first.
-
