What Do All of These Options Mean!?

Do you ever go to your local eye care provider and when ordering your new glasses, you have no idea what anything is that they’re asking you to order? Well I can tell you from personal experience that before I was educated about what all of the different options were, I would always just order the cheapest thing possible. I didn’t think that the other upgrades were really worth paying the extra money for.

In some cases, I was right, it was not worth it for me, but there are others that think the same way that I always did, when in fact, they would really benefit from some of the options that are available to them.

As a result, I figured that it would be a good idea for me to post about some of the options that are offered at most eye care providers, so that our readers can feel more confident the next time they order a new pair of glasses.
