OLUX non-invasively quantifies conjunctival ultraviolet autofluorescence, an objective biomarker of accumulated sun exposure and a predictor of the risk of myopic progression in childhood.
Every hour in the sun leaves a fingerprint on the conjunctiva. For the first time, that fingerprint can be measured.
— 01 / Product
Designed to see everything,
without touching the eye.
An ergonomic binocular headpiece that adapts its illumination to the conjunctiva and captures the CUVAF area at clinical resolution. Built for pediatric and in-office use.

— 02 / Technology
Three steps. One biomarker.
The device illuminates the conjunctiva with narrow-band ultraviolet light. Tissue that has been exposed to the sun fluoresces. The camera measures the area and the system delivers a reproducible CUVAF index.
01·UV
Controlled UV-A illumination.
A ring of LEDs at 365 nm excites the autofluorescence of the conjunctiva with no dilation or contact. Optical dose certified for ophthalmic use, including pediatric.
02·CV
Conjunctival capture and segmentation.
A calibrated binocular sensor records the fluorescence. Computer vision models delineate the CUVAF area with sub-pixel precision, reproducibly across observers.
03·DX
Longitudinal clinical index.
The quantified area is translated into a CUVAF index, comparable against age-based norms and trackable over time. The clinic gains an objective metric of myopia risk.
— 03 / Application
For the eyes that are still growing.
Childhood myopia is a silent pandemic. Scientific evidence links a lack of daytime exposure to its progression. OLUX delivers an objective metric where before there were only questionnaires.
Pilot study · Pediatrics
An optical fingerprint to assess outdoor life.
The CUVAF area reflects accumulated exposure to visible and UV sunlight over recent months. It's the first objective biomarker able to complement patient history and refraction in the pediatric ophthalmology clinic.

More sun, more fingerprint.
The CUVAF area is invisible to the naked eye. Under natural light, two eyes can look identical; under UV-A they reveal how much sunlight the conjunctiva has received in recent months. Hover over each eye to see its fingerprint.

A decade of clinical evidence.
The CUVAF biomarker is backed by peer-reviewed publications. OLUX systematizes that methodology and brings it into everyday clinical use.
