#023 You are not afraid
As an entrepreneur, you've knocked on many doors, you've taken risks, and you've learned from your mistakes to become stronger. But after long hours of conducting your business behind your computer screen, you suddenly find yourself having… sore eyes.
The spectrum of light that the sun emits is composed of almost equal parts blue, green, yellow and red. This relationship is essential to our proper biological functioning. For example, blue light from the sun helps regulate our mood, but it decreases in intensity towards the end of the day while red light promotes the secretion of melatonin to help us sleep well.
When we spend several hours a day in front of a computer screen, several phenomena can affect us:
1- The LED screen of computers emits a large amount of blue light, little green light and even less red light (see the Cool White LED image below). The color ratio differs greatly from that of natural light, which can cause fatigue and other eye problems. Indeed, prolonged exposure to blue light can cause damage to the retina (macular degeneration), and, after several years, cataracts.
2- LED monitors are made up of thousands of tiny bulbs that turn on and off several times per second, often 100 times or more. They are manufactured this way for reasons of energy efficiency and manufacturing costs. LED lights would consume way too much power and overheat if left on continuously. If you lower the brightness of your screen from its maximum brightness, the screen flickers more and more. By flickering like this, your monitor forces the iris in your eye to continually contract and dilate, causing fatigue, headaches, and eye pain.
To compensate for this exposure, I have been using Iris Pro for some time, an application that filters blue light from the screen and protects the eyes. Iris uses your computer's video card to reduce screen brightness without increasing screen flicker. The application also allows you to modify the color temperature in order to increase the quantity of red light emitted. It automatically adjusts the brightness depending on the time of day and the light around you. Result: I feel less tired after a day of work and I only have itchy eyes when it's time to go to bed.
With age, the eyes dry out more easily. Dry eyes are experienced by around a third of the population, and the discomfort adds to that experienced by the eyes and head after long hours in front of the screen. Moist heat therapy is recommended as a complementary treatment for people suffering from dry eye or other eyelid conditions, such as swelling or styes. In addition, cold therapy helps relieve eye fatigue, redness and the burning sensation that sometimes occurs when we “forget” to blink by spending too much time in front of our screen.
At the end of a long day, take the time to take care of your eyes by keeping them closed for a few minutes under a hot or cold mask. This will give you the opportunity to relax and even meditate, or simply daydream before tackling your evening tasks. Ask your optometrist to order the I-RELIEF™ , which I personally use, or look for a therapeutic eye mask during your next online shopping trip. For once, being cold will do you the world of good!
