New experiments by the Complutense University of Madrid in collaboration with the research group led by Professor Vega Álvarez of the University of Oviedo ratify the irreversible damage to the eyes that can be caused by light emitted from electronic device screens.

Effects of exposure to white LED light of screen with and without filter protection

Structural and gene expression studies have been carried out on retina of regular pigmented rats, divided in two groups:


The rat cages were surrounded by 6 marketed tablets that were turned on for 16 hours and turned off for 8 hours a day. The time of experimentation was 3 consecutive months.


GROUP 1: Exposed to white LED light without Reticare

23 % reduction of retinal cells

GROUP 2: Exposed to white LED light with Reticare


~0% reduction of retinal cells

Animal testing often serves as a reference for what we can expect in humans

This experiment has been carried out in less damaging conditions to animals. Specifically, the animals were young, with pigmented retina similar to that of a human, exposed for 3 months, and tablets screens that were selected are available for customers in the market (they emit less than the screens of laptops or smartphones).

Extrapolation may be done taking into account that the average lifespan of these animals is 8-10 years while that of humans in the developed world is between 70-80 years and were exposed to LED screen for 3 months.

Calculation of ocular lighting according to the user, device used, use distance and pupil diameter

It is based on the premise that LED screens emit light with a high proportion of short wavelength, a very energetic visible radiation that can produce damage to the eyes and to other structures of the body.


The emissions of LED screens of different marketed devices were measured and the amount of high energy light that reaches the eye was calculated for different pupil diameters.


-The amount of light that reaches the eye when they use a smartphone is 7 times higher than when they use a computer.

-Children receive 3 times more light than an adult who uses the same device, due to the shortest distance of use.

There is an epidemic of blindness on the horizon and we have irrefutable scientific data that suggests it. However, this information has only reached a small part of the society because of the complexity of the problem and the fact that technology is one of the main players in the global economy.

At Reticare, we have been defending your eye health for more than 3 years. We are a small company with a huge mission: we want people to know the risks of device screens and to take appropriate measures to reduce them.

Understanding the impact of scientific studies and giving them the importance they deserve is essential. Reticare is your ally. We want you to reduce the risks of retina damage with products resulting from more than 15 years of research that support its effectiveness.
