"Eye Sim" that you can experience how the world appears in its eyes when you enter your eyesight

When the naked eye's eyesight is good, I do not know the feeling that "the field of vision looks blurred" of the person wearing glasses, but if I enter sight data, the world that I see in the eyes of people with that value of sight The visual acuity simulator that you can experience is "Eye Sim"is. Eye Sim is a simulator developed by physicists at Harvard University and Warwick University, using a complex algorithm from vision dataZernike polynomialBy generating it, everyone can feel the "how the world is reflected in people with poor eyesight".

"Eye Sim" is easy to use, just input visual acuity at the top of the page and click "Simulate" OK.


Each item has the following meaning.

Sph (Spherical): Spherical power
A value indicating the degree of myopia / hyperopia. When the number is minus, myopia is expressed, and in the case of plus, it is hyperopia, and the larger the numerical value, the stronger is myopia / hyperopia.

· Cyl (Cylinder): astigmatic power
The larger the number, the stronger the astigmatism.

· Axis: Astigmatic axis
A numerical value that represents an angle difficult to see through between 1 and 180 degrees.

Everybody can feel the "sense of blurring vision" of the person whose visual acuity is lowered, such as "can not read the sign of the signboard", so once you use it, the admiration of "envy is envious" may be blown away I do not.
