Visual vision test, sphere -3.00, cylinder (astigmatism) -1.00, what does it mean?

Hello!

Spherical lens is what we usually call myopia, so your myopia is 300 degrees

Cylinder lens is what we usually call astigmatism, so your astigmatism is 100 degrees

If it is data obtained through vision testing, it should be credible. I don’t know how it is detected. Generally speaking, teenagers need to have their pupils dilated for optometry. Only by going to the hospital to have their pupils dilated and then having their pupils re-opted can they get effective power information. If you simply use a computer to evaluate the test results, it has no practical significance.

The above is my personal opinion. I hope it will be helpful to you. If you have any questions, you can send me a text message or email on the site!
