When will irreversible damages caused by light from device screens be revealed?

Being well informed today makes an important difference in the future. There are 500,000 people, including many members from the most important companies and institutions in the world, who already know the importance of protecting themselves with Reticare against the light emitted from device screens. In one way or another, people’s vision are already being damaged due to the extensive amount of time spent in front of screens. The recurring question is when will the irreversible damage start to become evident?

In 2017, a prominent group of scientists published a study that focused on how long it would take to cause damages to the retina of animals, resulting from exposure to blue light. The comparisons were between 0 and 3 hours, exposing the animals to the light for four weeks. During the experiment they checked the evolution of the study, first at two weeks then again at four weeks.

Even though at some parameters from the effects of blue lights were observable with only one hour of exposure per day, clear damages were observed at 14 days, with three hours of exposure per day.

During the following study, the focus was to evaluate the occurrence of changes in the retina, after three months of exposure, against tablets with and without Reticare. Used as a source of illumination, the animals were exposed to tablets, for three months, 16 hours per day. Unlike humans, animals tend to avoid the light source by not looking directly at the tablets. Therefore, their behavior in front of screens are different than humans. It should also be noted that tablets emit approximately half of the light in comparison to mobile phones. Another factor to note is that people began using these type of screens at around 2008-2010 therefore, spending about 10 years in average in front of them.


While the conclusions from lab results with animals may not present a predictable source of the effects in humans, it is feasible to think we can probably see retina damage risks in humans after 8-10 years of exposure to the light, with the condition of intensive usage, and it would not be a surprise to start seeing the following possible effects:

  • Retinal detachment
  • Macular hole
  • Retinal damage
  • Expected cataracts
  • Macular degeneration

Both Reticare and UCM have been warning about the risks of light from device screens for more than 5 years. However, only a few people have experienced the serious effects that could be disabling, in a short period of time since then. Now, many more people are beginning to suffer from the initial symptoms such as itchy eyes, blurred vision and headaches and, already almost 500,000 of those people have decided to use Reticare. Although the number of protected people is important, from the point of view of those possibly affected, it only represents a small percentage. Unfortunately, the majority of users remain "ill-informed" or not informed at all about the seriousness of the risks and the need to protect themselves with Reticare. Therefore, we feel it is highly important to share this information.

The UCM and Reticare uninterruptedly continue to study how to prevent the risks arising from exposure to blue light. Per the last experiment, presented at the Medical Association of Madrid, after three months of exposure to tablets, the number of retinal cells of the animals with Reticare on their screens did not reduce. Whereas, the animals exposed to tablets without Reticare, a 23% retina cell loss was discovered.

It is essential to remember that retina cell death is irreversible. Once retina cells are lost, they are lost forever.
