See how you're actually aging — and exactly where to focus first.
One painless retinal scan plus your lifestyle data produces a six-dimension wellness score and a personalized protocol — tracked over time on a cadence that fits you.
You'll see yourself in one of these — or somewhere between.
These two snapshots capture how most clients walk in: one already refining the last 10%, the other figuring out where to start. Most people land somewhere between them — and the assessment meets you wherever that is.
The Starter
You know something needs to change. You don't know what to fix first.
You know your habits could be better. Sleep, food, movement, stress — pick any of them. The volume of conflicting advice has you frozen, or you've tried five things at once and kept none of them. You want one clear, prioritized starting point instead of trying to fix everything at once.
You're motivated, but unsure where focused effort pays off most
You want a single, evidence-based place to begin — not another list
You want progress you can feel and see, not just track
The Refiner
You're 80% dialed in. You want the last 10%.
You exercise consistently. You eat thoughtfully. You sleep on a schedule and probably wear something on your wrist that tracks it all. You don't need more generic wellness advice — you need data that's actually about you, so you can refine with precision instead of guessing what to optimize next.
Your habits are solid; you want signal beyond steps and heart rate
You want a portrait that surfaces the one or two things still worth refining
You re-measure on your own cadence and watch the line move
Somewhere between these two? That's most people. The assessment doesn't care which label you'd pick — it shows you exactly where your wellness stands today, and the protocol calibrates around that.
The Science
Your eye is a live window into your body.
The retina is the one place in the body where blood vessels and neural tissue can be photographed non-invasively. Patterns in vessel caliber, tortuosity, and microvascular structure reflect what's happening cardiovascularly, metabolically, and cognitively — often years before other markers shift. The emerging field of oculomics studies these signals, and it's the foundation of what we measure.
“The retina is the only place in the human body where the microvasculature can be directly visualized in vivo, making it a natural window into systemic vascular health.”
Wagner et al., The Lancet Digital Health
Preventa Wellness pairs this retinal data with body composition, functional fitness, and lifestyle inputs to build a complete portrait of how you're aging — and what to change first.
Healthcare manages illness. Your genes set the baseline. The daily inputs in between — what you do Monday morning — shape the rest. That's the part we measure.

Your Wellness Portrait
Not one vague number. A portrait you can act on.
Six dimensions, each revealing a different chapter of your wellness story. One overall Preventa Score for direction — and the underlying detail for action. Here's a sample portrait.

Why It Compounds
Your score isn't the point. Your score over time is.
Any single number can feel like a verdict. It isn't. Your Preventa Score is a snapshot — a starting point. The real signal is the line that emerges when you re-measure: which habits moved your numbers, by how much, and how fast. A single score tells you where you are. A series of scores tells you what's working — and what to focus on next.

Sample trajectory across five visits. A focused shift in sleep timing first, then strength training added a year in. Each reassessment surfaced the next thing worth refining — not a hundred things at once. Cadence is personalized to where you are.
What to Expect
Not just better data — better mornings.
The science is the means. The point is the way the next year actually feels. When a focused protocol is followed consistently, the felt benefits tend to show up in a few familiar ways — not magic, just the compounding effect of pulling the right levers in the right order.
Steady energy through the day
Fewer afternoon crashes. The kind of energy that holds through dinner and the evening with family — not the kind that needs a third coffee at 3 PM.
Sleep that actually restores
When your protocol points at sleep, small shifts — timing, evening light, training cutoffs — tend to compound fastest. Sleep is often the lever most likely to produce a felt difference inside the first month.
Sharper mental clarity
Focus that lasts longer than the first meeting of the day. Less 3 PM haze. The mental version of physical energy — it tracks the same levers.
A clear next move
The feeling of finally knowing which lever to pull first — instead of guessing, second-guessing, or trying to fix everything at once. One thing, well, for ninety days.
These are typical outcomes when the protocol is followed consistently — not guarantees. Everyone's starting point and rate of change differ.
The Program
An ongoing partnership — not a one-time report.
An assessment is only useful if it changes what you do next. Preventa Wellness is designed as a program: a clear starting point, a protocol you can actually follow, and a structured way to come back and measure what's changed.
Baseline Assessment
Establish your wellness portrait across six dimensions. Identify the one or two areas where focused effort will compound fastest.
Personalized Protocol
A specific, evidence-based protocol matched to your scores. Designed to be followed, not skimmed.
Personalized Reassessment
Re-measure on a cadence that fits your portrait — the typical range is every three to twelve months, depending on where you're starting from. Each visit refines the protocol around what's actually working.
1:1 Coaching
Direct partnership with a Preventa Wellness coach to translate the protocol into the rhythm of your week. Currently being built — early clients will be invited first.

Common Questions
The questions we hear most.
No. Preventa Wellness is a wellness assessment, not a medical product — we do not diagnose, treat, or prevent any medical condition. Think of it as a high-resolution view of how your daily habits are shaping how you age, designed to complement (not replace) routine healthcare.
A high-resolution photograph of your retina lets us analyze blood vessel patterns, neural integrity, and microvascular structure — signals that reflect cardiovascular, metabolic, and cognitive wellness. The eye is the only place in the body where this kind of vascular and neural detail is visible non-invasively. We combine these signals with your body composition and lifestyle data to build your full wellness portrait.
Wearables track surface behavior — steps, heart rate, sleep hours. Routine healthcare focuses on illness. Preventa Wellness sits between them: structural and vascular insight from the eye, combined with body composition and functional metrics, translated into a protocol you can actually follow. Most of our clients use all three together.
A baseline assessment with full report and protocol is $299. Reassessments are priced similarly. Your cadence is personalized to your portrait — clients with strong baselines often re-measure annually, those with more to refine usually return every three to six months. Direct 1:1 coaching is being built; pricing for that tier will be shared with early clients first.
Your data is encrypted in transit and at rest, stored with security best practices appropriate to wellness data, and never sold or shared without your consent. Full detail in our Privacy Policy.
