Two PRECISION1 lenses sit in our contact lens range: the standard lens and PRECISION1 For Astigmatism. Both are prescription contact lenses, so an order needs a current prescription from the eye doctor who fitted you.
Your prescription answers this for you, so the useful skill is reading it. Look for the power, sometimes labeled SPH or PWR, which is the number written for each eye. If there are also CYL and AXIS values, your prescriber fitted a toric lens and the astigmatism version is the one to order. Base curve and diameter appear alongside those numbers and are part of the fit, not a preference, so match them exactly rather than picking the nearest available.
Right and left eyes often differ, sometimes by a lot, so read each line separately and order per eye rather than assuming a pair. If your prescription names a specific lens, that name is what to order.
Enter every value exactly as written, including the plus or minus sign on the power. A current, valid prescription is required for any contact lens order, and prescriptions expire, so check the date before you plan a large restock.
If a lens has stopped feeling right, or you want to move between the spherical and toric versions, that is a fitting question rather than a shopping one. Book time with your eye care professional and let the new prescription drive the order.
