Ask an Eye Doctor and Get an Answer ASAP
Hi. I'm online and happy to answer your question today.
One Rx, I would venture to guess, was written by an Optometrist and the other by an ophthalmologist. These doctors use different notation to write down eyeglass Rx's
hi, both are ophthalmologists..
Let's convert the first one to the same convention as the second. Using the magic of mathematics it changes to:
+5.00 + 0.50 x80; +4.25 +0.75 x110
Weird...very few ophthalmologists use negative cylinder phoropters...... But, as you can see, they are really the same Rx.
The small variance is within the amount expected on different refractions. Not significant at all.
Does this answer your question?
Especially when using streak retinoscopy on a 4 year old child :-)
Are you still there?
I guess you have stepped away from your computer.
