How To Choose Contact Lenses For Different Minus And Cylindrical Eyes?
Hello,. I want to ask. I’ve been wanting to wear contact lenses for a long time because I’m starting to feel uncomfortable wearing glasses. Well, when I wanted to buy contact lenses, I was confused about which minus one to buy. Because minus the right and left eyes are different. My right eye is -7.5 with -2 cylinder while my left eye is -5.5 with -2 cylinder. Should I wear contact lenses minus how much?
Hi R White,
Before buying contact lenses, opticians will usually recommend checking with an ophthalmologist first and taking proper measurements before using contact lenses. Contact lenses require a different size adjustment than glasses. Since your eyes are quite different minuscule, you should buy at least two pairs of contact lenses, each of which is the right size for your eyes.
Conversion of eyeglass sizes to contact lenses has its own table, usually optometrists and opticians have it. Although there is a fast way, for example, above -4.00 D is added +0.25 and above -6.00 is added +0.5, but this method is less accurate. Astigmatism with a size of less than -1.00 usually can still use ordinary contact lenses, but more than that it is necessary to use special astigmatism contact lenses. Usually the price is more expensive than other contact lenses.
In conclusion, you should not determine the size yourself. Consult first before using contact lenses so that the size is really appropriate and does not add to the complaints of your eyes.
