Can Narrow-Band Red Light Help Reduce Myopia? (3-Day Eye Length Results)

Hello, my name is Carl Soehne and this account has the goal to achieve the best possible eyesight. Many people are myopic, meaning that the eyes are too long. So we are going to research if there is a way to shorten the eyes.

There are studies suggesting that narrow band red light could be helpful in reversing myopia.

Other studies suggest that inverted contrast polarity in the form of reading white text on black background could shorten the eyes.

However, a combination of his methods, reading red text on black background, was not found to be helpful. I also tested out a combination of these methods, but a different one.

On the first day documented, I went to an eye doctor to get a precise eye length measurement. We used a Carl Zeiss IOL Master 500.

In my room, I blocked the light from outside and turned red LED stripes on. I measured their spectrum with a small spectrometer connected to my phone. They emit narrowband red light.

My computer was connected to a TV and in dark mode. No color filters were turned on. The TV eye care was turned off and Windows Night light was also turned off.

In this red illuminated room, I did things on my computer. My vision had two areas: the red illuminated room and the TV. Sometimes I read a book with white text on black background.

One day later I went to the eye doctor again: both eyes were measured 10 µm shorter.

Two days later, another measurement: right eye another 10 µm shorter, left eye the same.

Over three days: right eye −20 µm, left eye −10 µm.

I think it is a good start and will continue the experiment.
