It is in the picture a hidden number. But not everyone sees the same numbers, and depending on what you see, you may know whether or not you need help from glasses.
According to studies published by National Eye Institute Most people with visual problems in the United States are not aware of it and this image can be an alternative to identifying it.
What do you see in the picture?
Here is a brief approach to how your eyes are:
3246: If you notice this number, you likely have nearsightedness and astigmatism.
3240: On the other hand, if you see 3240 between all the points, your vision problem may be astigmatism.
1246: Seeing this number can be a case of myopia.
1240: Congratulations, you have healthy eyes and it looks like you don’t have vision problems.
What are astigmatism and myopia?
Astigmatism: It is a vision problem that occurs due to the curvature of the cornea or lens. No matter where the problem occurs, whether in the cornea or the lens, the effect will be the same, difficulty seeing from a distance and up close. Vision is blurred.
Nearsightedness: When the eye does not receive the reflection of light properly, it produces problems with focusing the eye. Myopia is usually characterized by problems with far vision.
Near objects can be seen more clearly but distant objects are blurred.
