Have you ever thought about how other people perceive reality? Depending on the condition and preconditions, it can be completely different.
1. the healthy adult
This is how a healthy adult person should see the world
2. cross-eyed people
Some people think that people who squint see images twice, as seen in some movies. But in reality, the brain ignores what one eye sees, so the image does not double. You can see what they see by simply covering one eye.
Nearsightedness is when you see close objects relatively well and the far objects become blurry.
Here the opposite, the distance is seen well and the near is blurred.
5. legally blind
People who are blind "in principle" see at most abstract outlines, colors and light. They are called so because they cannot lead the life of a sighted person.
6. late loss of vision
This is what people see who have lost their sight and can only perceive changes in light. Light and dark - that's all there is to it. Usually these are people who were born with sight and later went blind.
7. completely blind
Who would have thought it - a complete blindness is absolute darkness. But a blind person would not describe the world as black, already because he does not know this color at all. By the way, they don't see anything in their dreams either.
8. color blindness
There are different forms, the most common is deuteranomaly, where all colors (especially red/green) lose saturation.
9. a newborn baby
This is what a newborn baby looks like. The image is completely blurred. In principle, a newborn baby can only distinguish light/dark.
10. one month after birth
After one month, it reaches for large objects about 20cm away. For example, the mother while breastfeeding.
11. 6 months after birth
After 3 months, the baby can distinguish the faces of the parents. They begin to see colors - red and yellow first and best.
It takes more than 1 glass of wine to be this drunk, the image shows a heavily intoxicated state.
