History of Vision Correction…Do You Know Who Invented the Bifocal??

Did you know that in 20AD a Roman named Seneca looked thru a globe of water in order to help him magnify the print in the ancient Roman Books?

Did you know that in 60 AD the Roman Emperor Nero wore eyeglasses with LENSES made of EMERALDS to view the gladiator games?

Did you know that in China (around 1430AD )judges used to darken their glasses for the purpose of concealing their eye expressions in court?

Did you know that in the late 1600’s they used to keep glasses on their noses by using silk ribbons tied to the rims of the glasses and then hung the ribbons over their ears….with weights on the end to help keep them in place?

Did you know that in the 1700’s wealthy American colonists would search through basketfuls of spectacles imported from Europe to find the ONE pair of glasses that had the right prescription in them?    Did you know that they paid as much as $200 PER PAIR for their glasses…in the 1700’s ?!?!?

Optometrist, Ophthalmologist, Optician … What is the Difference?

Many people often ask – What is the difference between an Optometrist and an Ophthalmologist??

… OR …

What is the difference between and Optometrist and an Optician??

Well, HERE is the answer for you:

Optometrists are Doctors of Optometry.  They act as Primary Care Doctors for your eyes. They are experts in vision care, eye health and eye function. They prescribe glasses and contacts and can diagnose and treat eye diseases (like pink eye, glaucoma, eye allergies, eye ulcers, styes, eye inflammation etc.) with various forms of medication.  They are also trained to remove certain types of foreign bodies in the eye.  They usually have 4 years of college education, 4 years of Post-Graduate Doctorate work in Optometry School and some Optometrists elect to do a 1 year Post-Doctorate Residency.

Ophthalmologists are medical Doctors of Ophthalmology that deal primarily with the diseases of the eyes, which they are able to treat with medicine and surgery.  Most ophthalmologists act more as Seondary Care providers for your eyes – since most are eye surgeons.  They can also prescribe glasses and contacts – but, you’ll find that most ophthalmologists concentrate their practices primarily around eye surgery and treating various eye disease.  They usually have 4 years of college and 4 years of medical school and then they complete a Post-Doctorate 3 year Residency in Opthalmology to learn about the eye, eye disease and various ophthalmic surgical techniques.

Opticians are experts in optics, optical lenses and frames.  Opticians fill the prescriptions for eyeglasses and contact lenses that have been prescribed by Optometrist and Ophthalmogists.  They fit, sell, dispense and repair eyeglasses.  In some states they can also fit contact lenses.  Their education requires a high school diploma and 2 year Opticianary program (or a 3-5 year Opticianary apprenticeship).
