Lens Basics.
Let's face it. There are lots of lens choices out there. We admit, it can be confusing trying to decide on the best lenses to choose. To make it easier, we'll ask you simple questions about your lifestyle, hobbies, the type of work you do and what makes you feel comfortable. We can also duplicate your new glasses based upon what you currently wear.
We must keep up with the latest, cutting-edge technology, whether it's new lenses or current styles of frames. We do this through continuing education and reading the latest industry publications.
We have compiled this list of the most popular lenses available, along with a glossary of terms you are likely to hear when discussing your eyesight with your doctor. We can't emphasize the importance of taking the advice of your doctor when it comes to your new prescription.
