About 64-percent of the people in the United States have to wear eye glasses to correct their vision.
After you visit the eye doctor, glasses are designed to fix your specific problem.
Carla Burbidge show us how it's done, in this week's Eye on Health.
At Vision Galleria in Minot, after a doctor orders an eye prescription, the next step is the bank, a lens bank, where they have many different types of plastic lenses.
Steve Nyre is the Optical Lens Manager, and he'll make up to 40 pair of eye glasses every day.
And if it's not a complicated prescription, it doesn't even take long to make a pair of glasses.
(Steve Nyre, Vision Galleria) "Some I can do in 15 minus, like a child single vision prescription."
Every order from single vision to invisible bifocals, comes to Steve, and using technology he turns out each pair of glasses.
Computers shape the lens to fit the frames the patient has selected.
Steve's been in the business many years, it used to be glass frames that had to be cut by hand, but times have changed.
Now it's plastic that will be cut by a machine.
When Steve is out the community, he can see his glasses on many faces.
(Steve Nyre, Vision Galleria) "I've made so many glasses, I know lots of people."
As the computer finishes up the job, it's another pair of glasses that will make it possible for a person in our community to see clearer.
For Eye on Health I'm Carla Burbidge.
