Expanding the range of human vision to the near infrared: bioexperiment
The authors of the experiment to expand the range of human vision reported the first successful results ! After two weeks on a special diet, the patient began to see flashes in the range of 950 nm (near infrared radiation), which is usually indistinguishable to the human eye.
A group of scientists announced the experiment in October 2013 . They managed to raise through the crowdfunding campaign $ 4,000 needed to purchase equipment. The main item of expenditure is a device for electroretinography, which registers the biopotentials arising on the retina of the human eye during light stimulation. The illustration above shows the readings of this device for flashes of light at different frequencies of radiation.
In order to “teach” the human eye to see in the near infrared, it is necessary to take doses of vitamin A2 for a long time. He is responsible for the ability of the retina to distinguish objects in the dark (near IR). At the same time, it is necessary to limit the intake of vitamin A1, which is responsible for the overall functionality of the photoreceptors on the retina.

The fact is that the proteins responsible for the transport of vitamins through the cell membrane are much better adapted to the transfer of A1 than A2. A specific diet allows the body to rearrange and “load” more vitamin A2 into the retina, which helps to improve sensitivity in the near IR (that is, a person begins to see in the dark).
The experiment confirmed the theory of researchers. Before the experiment, the patient saw only flashes in the range of 850 nm, and now he distinguishes between flashes and 950 nm.
