Practice tips to help you have a supermarket

The structure of the human eye means we all have a "blind spot" , which makes us unable to see some things right in front of us. However, researchers found that regular exercise can shrink the "blind spot" size and make us superhuman.

According to experts, our optic nerve, which is responsible for transmitting visual signals to the brain, must pass through the retina, forming a hole in this light-sensitive tissue. When images arrive at this precise position, we will not be able to capture them, which means that we cannot see the image creation in front of us.

A new study published in Current Biology has published good news: The blind spot can actually shrink through exercise, although we can't erase the gap in our vision.

The team trained 10 people to perform the task of distinguishing the direction for 20 consecutive days, in which they were shown a slow-changing sinusoidal waveform with a circle focusing on the physiological blind spot of a eye. The size of the circle is adjusted so that volunteers can accurately guess the direction of movement in about 70% of the test time.

As a result, at the end of the training process, volunteers showed improvements in the ability to accurately evaluate both direction and color of the waveform.

Practicing in one eye does not remove the blind, blind spot from practice, implying improvement is not simply a matter of training. Instead, according to the study group, the results were consistent with the idea that exercise enhances the sensitivity of nerve cells to receptor fields, which are overlapping or partially contiguous with physiological blind spot.

Therefore, the trained eye clearly becomes more sensitive to weak signals, originating primarily from the "blind" area of the eye.

Experts say that if exercise can reduce the non-visual associated with physiological blindness, it may prove the same effect in other "blind" cases, such as helping Improve vision for patients with age-related black spots.

The practice can also be used to assist in recovering human eyesight in addition to other developing technologies, such as biological simulations or retinal stem cell therapy.
