Over 20 years of experimental research on the biological impact of light radiation on the human retina.

Over 20 years of research

The reality of high-energy light

The human visual system evolved to interpret light reflected off objects — never to stare directly into an intense, close-range emission source.

Modern technology has broken that biological rule. We spend more than 8 hours a day exposed to direct LED emission — with peaks in blue light (380–500 nm) and green light (500–590 nm) — creating an overexposure scenario we were never designed for.

Unlike skin, the retina <strong>has no regenerative capacity.</strong> Cumulative exposure to high-energy light is a studied fact.

Devices comply with current regulations — but those regulations are outdated. They were designed for brief exposures, not the chronic, repetitive use that defines our digital reality. reticare® has been developing optical filters to reduce that exposure for over 20 years.

Science studies it

The light UCM studies doesn't hurt and gives no warning

High-energy blue light (380–500 nm) and high-energy green light (500–590 nm) are studied for their effects on retinal cells. They affect central nervous system neurons. They cause no pain.

Dr. Celia Sánchez-Ramos

The science behind reticare® was born at the university

Dr. Celia Sánchez-Ramos, researcher at the Universidad Complutense de Madrid, has spent more than two decades studying the impact of high-energy light on the human retina.

Her research — validated in vivo and in vitro and published in indexed international scientific journals — is the foundation of all reticare® technology. It is not an accessory. It is applied science with an international patent.

01

Blue light (380–500 nm) and its effects on the retina

UCM research studies how high-energy blue light relates to oxidative stress and photoreceptor cell behavior. A finding confirmed in experimental studies with animal models and donor human cells.

02

Green light (500–590 nm) and cumulative exposure

Overlooked for decades, high-energy green light is studied under prolonged exposure. UCM research confirms it — reticare® is the only technology that incorporates a filter for both spectra.

03

Optical filter behavior — studied in vitro and in vivo

UCM studies describe, in in vitro and in vivo models, the behavior of selective optical filters against high-energy spectra (380–590 nm).

04

Optical filter behavior under continuous use

UCM studies describe filter behavior under chronic exposure and real daily use (Sánchez-Ramos et al., Cells, 2021).

20 years of research. One optical filter.

RetiNaut glasses are the direct result of this research. The only optical filter developed from +20 years of UCM scientific research.

reticare — scientific optical technology

Our reason for being

From scientific evidence
to real reduction

reticare® was born to turn decades of scientific research into real solutions. We don't design accessories. We apply science.

01

Optical function, not aesthetic

Every product is designed under biomedical criteria validated in vivo and in vitro. Form follows function, never the other way around.

02

Science before marketing

The direct result of research by Dr. Celia Sánchez-Ramos (UCM). More than 20 years of real evidence, not trends.
