Contact Lens City

First of all, is the prescription that you’ve given for contacts or spectacles?? I’ll assume that it’s for contacts and answer your question.

You do have quite a bit of astigmatism ( telling from the CYL). And you want to use spherical contacts instead of toric…So let me calculate the spherical equivalent of your perscription:

Left Sphere – half Cyl = -3.50-0.75 = -4.25
Right: -2.25-0.75 = -3.00

This means that if you had to wear non-toric/spherical contacts, then your left eye would need -4.25 and your right would need -3.00.

Yes, your vision will be blurry: 1) your prescription is higher than the lenses you have 2) your astigmatism is quite high so I would recommend getting toric lenses instead. But it also depends on whether or not you have been using cyl in your prescription…If you have not, then maybe -3.75 and -2.75 will not be too bad.

Try them on! See the difference for yourself It’s not going to harm your vision. Just discontinue them if your vision is blurry. Simple!

Hope this helps.
