This video covers the basic optics you need to know to understand basic glasses prescriptions.
When I began my ophthalmology residency, I had no idea how to read or write a glasses prescription. In this video, I try to explain the basic topics I wish I had known. This includes lens theory, basic spherical problems (near and far-sightedness), astigmatism, cylinder conversion, and presbyopia (bifocals). While this lecture is “basic” and assumes you have no prior glasses experience … this is still important stuff. I hope you find this useful!
