Bifocal Lens Demonstration & Fitting
Description
I got tired of switching between two pairs of glasses -- one for reading, one for distance. So I cut the lenses in half and combined them. Revolutionary? No. Practical? Enormously. This workshop covers basic optics, lens grinding principles, and why bifocals work. Tip: The best inventions solve annoyances, not emergencies.
