NEW EXPERIMENTS

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:

METHODOLOGY:

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.

RESULTS:

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.

METHODOLOGY:

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.

RESULTS:

-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.

UCM investigation

1 – Lab Rat Experiments 2002 – 2003

1  Year trial High exposure to blue light without filter.
Conclusion: The test results indicate when the retina is exposed to short wavelength light and photo-proteccion at a radiation of 450 there was retinal damage found.

2 – Lab Rabbit Experiments 2003 – 2005

2 Year experiment consisting of longitudinal and transverse studies Experiment consisted of chronic exposure to short wavelength light in cycles of light/dark (12/12). Rabbits were implanted IOL in one eye and the contra lateral eye was left without filter.
Conclusions: We observed pro-apoptotic gene activation in the unprotected retinas and activation of anti-apoptotic genes in the photo-protected retinas.

3 – Human Clinical Trial 2006

7 Years (longitudinal and transverse) Longitudinal study (conducted over a period of time) and cross-sectional study (comparing two eyes) operated from cataract; an intraocular lens was implanted in one eye with filter and contra lateral eye was left without filter. Average age 77 years.
Conclusions: A decrease in macular thickness was observed in eyes without protective filter, as well as a diminution of thickness caused by age. The study also indicates the eyes without photo-protection have higher prevalence to eye diseases. The macular eye thickness with the protective filter remains without change (it does not age).

4 – In Vitro Experiments 2013

Cells of the human retinal pigment epithelium exposed to light LED (monochrome white 5400ºK and 468 nm, 525 nm, 618 nm) to 7cm 36h apart on circadian cycle (12 light / 12 darkness), with and without protection.

Conclusions: No photo-protection cell death is observed in more than 90%. With photo-protection survival rate is approximately 83%.

Among the prestigious entities internationally recognized that warn of the risks of potential damage to the retina caused by overexposure from short wavelength light are:

2009 – The American Academy of Ophthalmology states in addition to ultraviolet light, visible light with high energy can cause photochemical damage to the retina.

2011 – White LED light derived from LED blue light, emits high levels of visible light with high energy. Hence, the reason, the French agency for Food, Environmental and Occupational Health Safety (ANSES) in France warns of the potential retina damage that can occur especially in children derived from a chronic exposure to short wavelength light.

2015 – The Government of Taiwan, one of the leading manufacturers of technology in the world, prohibits children under the age of 2 to use electronic devices such as tablets and smartphones, and limits their use in adolescents, with fines of up to $ 1,600.

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.

The international media has reported on this problem
