If your eyeglass RX is very strong (like mine is), it's really worth it to pay a little extra to get High-Index lenses
They're thinner and more lightweight - read: more comfortable - than your typical progressive lenses. 8-)
How to Read and Enter Your Eyeglass Prescription
While you don't need to completely understand how to read your eyeglass prescription to place an order on AC Lens, you'll need to know the basics in order to select and order the right lenses for your eyes. We've provided assistance with how to read and enter your prescription in the information below. If you don't have a copy of your prescription, or are not sure how to read it, rest assured that as long as you have your doctor's information we can contact your doctor directly in order to obtain your correct prescription.
How do I read my eyeglass prescription?
Your prescription should look somewhat similar to the following:
Below are examples of how a prescription can look and how it would be entered into our website.




How do I know if my prescription is Single Vision or Bifocal? Or Progressive (Multifocal)?
Doctors write prescriptions in many different ways. Below is an explanation of how to tell if your prescription is for single vision or bifocal lenses.
SINGLE VISION
Single Vision prescriptions are for patients who have trouble seeing either near or far (but not both). An example of a Single Vision prescription can be seen below. As you can see, the prescription has no value in the ADD column.

BIFOCAL / PROGRESSIVE VISION
Bifocal prescriptions are for patients who have trouble seeing both near and far. An example of a Bifocal prescription can be seen below. As you can see, the prescription has a value in the ADD column. You will only have an ADD measurement if you wear bifocal/progressives lenses.

ADD corrections are almost always the same number for both eyes. If you happen to see the letters PAL next to one of the numbers, or written elsewhere on your prescription, this means your doctor indicated that you will need a different ADD correction for progressive bifocals versus lined bifocals. Since AC Lens only offers Progressive Bifocal lenses, you'll want to use the number with PAL next to it when entering your prescription on our site. That number will apply to both eyes so make sure you enter it on both eyes. Below is an example of a PAL prescription:

What if my prescription has a value in the Prism column?
Unfortunately, AC Lens is not currently able to create glasses with Prism corrections. An example of a prescription with a Prism correction can be found below:

I want to purchase eyeglasses through AC Lens, but this prescription stuff is confusing. Is there an easier way?
Absolutely! You can always leave the prescription fields blank when ordering, and then either send us a copy of your prescription, or give us your eye doctor's contact information and we will collect your prescription information directly; ensuring that your prescription is correct while you remain free of worry!
