some people He doesn’t wake up when the ball explodesSome people even open their eyes when they feel a little light. If you have problems with the light transmission of your eyelids, this content is for you.

Let’s tell the good news up front: it is true It’s not a subject you’re very sensitive about. So what is it about?

This is caused by your eyelids letting in too much light.

“How can light penetrate when the eyes are closed?” Don’t think twice, because there are studies on the subject. A study conducted by Osaka Metropolitan University produced some striking findings on how much light the eyelids let through when the eyes are closed.

According to the work of Hideki Sakai: eyelids let much more light through and this affects the quality of sleep. In particular, the amount of light perceived with eyes closed was much higher than previous estimates.

This is because the eyelids are usually let more light through and therefore it can be easily influenced by external factors during sleep.

In his research, Sakai tested how participants perceived light, even with their eyes closed.

The findings of the study among 33 people, light transmission in the eyelid values ​​can be much higher than expected (ranging from 0.3% to 14.5%) and show how different light colors affect perceived brightness.

This information, obtained by reflecting light of different brightness levels onto people, is important for understanding how lighting conditions can be created during sleep or in low-light environments.

According to Sakai’s statement: It is of great importance to correctly understand the lighting environment when the eyes are closed and to develop appropriate lighting solutions based on this information, both during normal sleep and in other special situations.

The study also revealed the effect of the color of light on sleep.

Red light in particular is perceived as brighter, It has been observed that blue light is perceived as darker. It is clear that knowing this will not only improve our sleep quality, but will also be useful in lighting design.
