Hello. Permission to ask, I’m the minus and cylindrical eyes. Now, I checked my eyes in optics, the results were minus -0.75 and cylindrical -0.5 left and right axis in the right eye 90 ° and left 80 °. Then I bought glasses, but it turns out that the lens is the wrong axis so the left one is 180 °, when it is worn it’s just comfortable. But according to the doctor does it affect my eyes? Should I buy more glasses or still use this?

Hello Devi, Thank you for the question.


Minus eyes or myopia is a refractive eye disorder that causes a person to have blurred vision when he sees objects far away. This condition is caused by the shape of the cornea that is too convex or the eyeball is too long so that the shadow of objects exposed to light entering the eye does not fall right on the retina but fall in front of the retina. On the other hand, a cylindrical eye or astigmatism is a blurred or shaded vision condition because the cornea or the lens of the eye is not completely convex which causes the light of objects that enter the eye not to fall at one point on the retina.


In the eye examination of the cylinder, in addition to checking the strength of the lens that must be used (in your case 0.5 diopters), it is also necessary to examine the lens's curvature (axis) which results in degrees from 0 to 180 degrees. Information about this axis is needed to correct the cylinder eyes to that degree. Thus, if something goes wrong making glasses, you should replace them with glasses that match the results of the examination. This axis error can later affect your vision (your vision becomes blurred at a certain time). It is recommended that you do an eye check on the eye specialist to avoid eye examination errors.


Hopefully this information is useful.
