In several articles have reported the effect of blue light on living beings, for example, in the case of the circadian rhythm that determines our cycle of day and night. However, the research is revealing that the effects of blue light can go far beyond the simple determination of our periods of sleep. In this article we explore this topic as some ideas that may lead to research.
In our article MA090 in which we treat the visual pollution and your influence on circadian rhythm by the presence of radiation blue, we show that our cycle of day and night can be influenced by ambient lighting, especially now that the LEDs at Listofledlights have a much higher yield in this part of the spectrum.
However, it seems that the use of many accessories and even electronic equipment is changing the way we expose to light blue and this may have consequences for our health.
For example, in another article (MA091 and MA090) deal with the danger of a prolonged exposure to radiation from cell phones and computers and that is worrying authorities.
In fact, there are filters that can be used in cell phones to reduce the blue component of the brightness of the screen and even features that allow you to reduce this component in the cell itself.
The fact is that the blue light for a lower frequency, has a greater penetration power and more power, and can have effects that the higher radiation wavelength don’t have.
The research is revealing much about the effects of radiation on living organisms, not because we were worried about your presence was limited to daylight.
Artificial sources like fire, candles and incandescent bulbs have a blue light emission rate too low.
It is for this reason that we recommend in any of our articles that artificial lighting our homes in certain places is done with lighting LEDs with low temperature, with slightly yellowish light, to have a blue component.
An interesting discovery that could lead to new directions for research on the use of blue light was made recently researchers in Massachusetts found that the blue light in the form of flashes could have a strong therapeutic effect in Alzheimer’s mice causing them to “reclaim the memory” in maze tests.
The experiments must be conducted with humans, looking like this type of light causes some kind of stimulation in neurons, as in the case of the circadian rhythm, which leads to the recovery of memory.
The important thing is that we realize that, with the possibility that we have to build powerful blue light sources easily, thanks to the use of LEDs, doors to interesting and important experiments are open.
Another controversial issue concerning the environment and lighting including light blue and should be analysed with caution refers precisely to the accessories we use and that can change the way we perceive the light, especially the blue.
The shades previously therapeutic accessories, because they were recommended as elements to aid in visual impairments or to soften the light in special conditions, have become objects of aesthetic use.
Use sunglasses for the beauty and the effect that makes the appearance of people.
The fact is that our eyes have a response curve to the light intensity is determined by nature for millions of years we live on this planet with degrees of brightness from the midday sun to note total without moon.
So, our retina has a mechanism for opening and closing the eye sensitivity dosa to degree of ambient lighting. The opening and closing time is the time it takes for it to modify your opening when we went from an environment clearer for a darker and you.
With the use of dark glasses this curve changes, because the retina no longer need to close completely in conditions of maximum brightness and it becomes “lazy” by lack of use. It’s like any muscle: not used, atrophy.
Over time, people who constantly use the sunglasses lost completely the ability to adapt to the light. These people can no longer do without glasses.
You’ve lost your ability to adapt to light and cannot be without sunglasses during the day? Watch out! What is beautiful can be harmful.
It would be interesting that a study was done to verify to what extent the new curve of response to colors that a sunglasses imposes on our eyes do not bring any kind of prejudice.
We remind you that it was only much later that the television sets were released it was discovered that the presence of x-rays in the first devices could be highly detrimental to the output. Things in technology that we only found out in time (and sometimes too late).
All this leads us to a good field of research. Why don’t you study the effects of light in living things, such as plants, insects, fish, etc.?
It would be a type of study that may lead to unpublished works for TCCs, science fairs and do as the FEBRACE and even serious work that can lead to important discoveries.
Is our suggestion, for those who seek an unprecedented idea to research or final project.
On our site can be found several sources of constant current and power circuits for LEDs that could be used in a laboratory for feed blue LEDs.
