THE EYES – NOT JUST ABOUT VISION
Few people know that the eyes have their own role in the biological clock.
How does the beauty of the world come into being? Light falls on the retina and then proceeds to a zone of the hypothalamus known as the suprachiasmatic nucleus. The nucleus is a circadian rhythm generator, and simply put it synchronizes the tick of these biological clocks. The neurons in the nucleus adjust to light information coming from the outside world through the eyes.
And now the most interesting part. If this mechanism fails, the organism’s internal rhythm ceases to correspond (or be adjusted, if you will) to the daily rhythm of the planet. As a result, you start to get up at a different time, which is poorly combined with work and other requirements of society.
It’s about falling out of the 24-hour cycle. 70% of completely blind people suffer from this problem, and every third blind person still retains the retinal neurons necessary for the operation of the biological clock. In other words, the breakdown is happening in another area.
And it’s clear that now we are electrified in every aspect of civilization, violations of this 24-hour cycle are increasingly affecting the sighted.
The biological clock is connected to all systems in the body, including vision. Understanding this fact leads us to a fashionable modern theme – the possibility that the effectiveness of treatment on certain ailments (for example, surgery) depends on the time of day. Is it better or wiser in the morning or the evening? That’s the question.
