Eye Protection Antioxidant
Eight-plus hours of screen time daily, taking lutein capsules yet unable to feel the difference? What goes in doesn't equal what your body can actually use. The Eye Protection Antioxidants Analysis measures five fat-soluble nutrients in serum — lutein, zeaxanthin, lycopene, beta-carotene, and retinol — quantified by UPLC (Ultra-High Performance Liquid Chromatography). It tells you whether you're truly absorbing what you supplement, or whether your intake is falling behind your daily oxidative load.

What is this test for?
透過【血液】檢體，同時偵測黃斑部色素核心成分（葉黃素、玉米黃素）、間接保護劑（茄紅素）與視覺循環原料（β-胡蘿蔔素、視黃醇），比膳食問卷更客觀、比保健品標示更貼近身體實際吸收狀態，是評估眼部抗氧化儲備量與藍光防禦力的關鍵鑑別工具
Diet questionnaires and supplement labels only tell you how much you took in. Fat-soluble carotenoid absorption depends on gut microbiome, bile secretion, co-ingested fat, age, and individual genetics — variables that can differ up to threefold between people. Serum measurement reveals what your body has actually made bioavailable. Three defense layers are quantified simultaneously: macular pigments (lutein + zeaxanthin), indirect protector (lycopene), and visual cycle precursors (beta-carotene, retinol). The pattern tells you whether you face universal depletion, targeted deficiency, or over-supplementation. Analyzed by Ultra-High Performance Liquid Chromatography (UPLC) — the advanced successor to the HPLC technology used in AREDS2, NHANES, and other landmark epidemiological studies. Operating on the same principle but with finer separation resolution and lower detection limits, UPLC delivers more precise quantification of trace-level fat-soluble carotenoids in serum. A large epidemiological study (Mares-Perlman et al., Arch Ophthalmol, 1995) found that individuals in the lowest serum lycopene quintile had approximately twice the risk of Age-related Macular Degeneration (AMD) compared with those in the highest quintile. Studies indicate that individuals with higher blood concentrations of beta-carotene and other carotenoids show over 30% lower risk of progressing to advanced AMD.Supplements not working, or simply not absorbed?
Serum levels, not dietary recall
Full antioxidant spectrum coverage
Beyond research-grade instrumentation
Daily lutein capsules but no perceptible difference? Fat-soluble carotenoid absorption varies dramatically between individuals. Serum levels reveal whether the amount actually reaching your bloodstream meets protective thresholds — so you're not spending months on a regimen that isn't doing what you hoped. Research shows 400–460nm short-wavelength blue light is a primary driver of retinal photo-damage, and macular pigment is the body's only natural filter for this band. If your daily screen time exceeds 8 hours, pigment depletion may be outpacing what your diet replenishes. Vitamin A (retinol) deficiency leads to corneal epithelial dryness and impaired low-light adaptation. If headlights feel harsher at night or artificial tears have become a daily habit, the baseline raw material for your visual cycle may already be insufficient. Carotenoids cannot be synthesized by the human body and must come entirely from diet — dark leafy greens, orange-yellow vegetables, tomato products. People relying on restaurant meals or consuming fewer than 5 servings of produce daily often have serum levels well below recommended ranges.Eight hours of screens a day — are your eye reserves keeping up?
Taking eye nutrients without knowing if they work
Extended blue-light exposure
Persistent dryness or reduced night vision
Eating out often, low vegetable intake
"Vision doesn't fade overnight — it loses a little each day, until one day you realize you can no longer see clearly."
The macula is just 5 millimeters across at the center of your retina, yet it carries 90% of your sharp vision and color perception. With no blood vessels of its own, it relies entirely on a "natural yellow filter" made of lutein and zeaxanthin to absorb high-energy blue light and neutralize oxidative stress. The thickness of this filter is what clinicians call macular pigment optical density (MPOD).
The catch: the human body cannot synthesize either pigment. They must come from diet. When you're exposed to 8+ hours of screen blue light and outdoor UV every day without replenishing them, the filter thins like a worn-out sunscreen film. By the time symptoms of macular degeneration become noticeable, pigment depletion has typically been accumulating for over a decade. A serum panel lets you see your reserves before symptoms force the question.

If you already experience blurred vision or visual distortion, please consult an ophthalmologist first. Results are best interpreted with a registered dietitian or physician.
Age-related Macular Degeneration is the leading cause of blindness in adults over 60 in developed countries, with global cases projected to reach 288 million by 2040. Lancet Global Health, 2014 A landmark clinical trial (n=4,203) demonstrated that 10mg lutein + 2mg zeaxanthin daily reduces progression to advanced AMD in high-risk individuals. JAMA Ophthalmol, 2014 (AREDS2 Report No.3) High-dose supplementation groups show statistically significant MPOD increases from week 8, continuing through week 16 (p<0.0001) — one of the rare nutritional interventions verifiable within months. Scientific Reports, 2020The day you notice blur, the depletion has been building for a decade
"I take lutein capsules every day — that should be enough, right?" Fat-soluble carotenoid absorption depends on gut microbiome, co-ingested fats, age, and individual genetics. The same dose can produce serum levels that differ threefold between people. Taking it isn't the same as using it — serum measurement reveals the actual outcome. "My eyes feel fine — I'll check later if something goes wrong." Macular pigment depletion is gradual. By the time visual symptoms appear, depletion has often been accumulating for over a decade. Once structural retinal damage occurs — distortion, blurring — the changes are largely irreversible. "I just eat more carrots and tomatoes — that should cover it." Carrots are rich in beta-carotene and tomatoes in lycopene, but neither is a direct precursor to macular pigment. Without dark leafy greens (kale, spinach, sweet potato leaves) to supply lutein and zeaxanthin, there may still be gaps in your defense. "More is better — anything extra just gets flushed out." Lutein, zeaxanthin, lycopene, beta-carotene, and retinol are all fat-soluble. Excess accumulates in the liver and adipose tissue. Preformed vitamin A in particular can cause hepatotoxicity and bone loss when over-consumed. "I'm still young — I don't need to worry about this yet." Studies show healthy young adults with 8+ hours of daily screen exposure already have MPOD below their age-group average. Macular pigment accumulation is a long game — building your baseline at 30 is more meaningful than scrambling at 50. "Even if I'm deficient now, it's probably too late to fix." Not so. Clinical trials confirm MPOD is one of the few nutritional markers that show measurable improvement within 8–16 weeks of correct supplementation. The body responds — provided you know exactly what's missing.Have you ever thought this? Six common misconceptions about eye nutrition
The Eye Antioxidant test shows whether your reserves are sufficient — but those reserves are shaped by absorption efficiency, hepatic metabolism, inflammatory state, and overall micronutrient balance. A single panel can't answer those upstream questions.
A focused assessment of eye-supporting nutrient status — suitable for those with a specific concern or working within a budget. Beyond eye antioxidant reserves: why aren't you absorbing well? Which systems are depleting them faster? What do you actually do about it?
"The eye antioxidant test tells you how thick your filter is — Body Decoded tells you why it's thinning, and which layer to rebuild first."
