Optics is difficult and not my favorite. I go to SUNY but this interactive lens applet might help.

I have a feeling you are way beyond this though.

I struggled a bit in Optics in the beginning of the semester. I talked to someone in the school about getting tutoring. You should ask your professor who you can go to for some extra help.

are you guys talking about GEOMETRIC optics? like the stuff you learn in physics? how much more complicated is it than say your Physics 2 course in UG that covered it?
(sample questions?)
(sample questions?)
The first couple weeks of geometric optics (which you take the first semester) are just like what you learn in physics 2. It gets much more complicated.
Example question from our last unit:
" An optical system consists of a lens with an aperture placed in front of it and a second aperture behind it. The object space conjugates are a 25mm diameter aperture 500mm from the object, a 25mm diameter lens located 100mm behind the 25mm aperture, and a 36mm diameter image of the second aperture located 250mm behind the lens. The lens is the entrance pupil of the system. Describe the entrance port and field stop of the system."
NOT looking forward to studying that crap again for boards.. lol

oh i see, thanks for that!
It doesnt look too bad i think, even though i cant answer that because i havent seen the material. Hope you guys get to use calculators lol.

3 and 1/2 years out of school, i still have never used any optics formulas one day in practice. If I did Low Vision I could maybe see a few calculations til you got good at predicting what a patient would need.
I wouldn't stress out too much about optics. Learn it for the boards, but you will use it very seldom, unless you plan to go into research.

I talked to a 4th year who spent 6 months at a VA where they do a lot of low vision and he said that you use 2 formulas in low vision:
1. Calculating a patients JND
2. Calculating the equivalent power needed to give the patient their desired VA
Not exact rocket science lol
That being said, I really hate optics and I too am not looking forward to studying it for boards in March.

Seriously, you're spamming with a cancer support website? What the hell is wrong with you?

As a first year student at Nova, I can say that the problem that we have here with optics is not so much the material, as it is the professor. For example, our class average on the final was 71 percent....This is a common thread of first year; exams (such as in anat, micro, optics) that saw averages either failing or a few points above...Saying this, I know how hard a lot of us work, and when a group like ours has that low of an average, that is no longer our fault, in my opinion.
As for optics, the primary problem is the fact that 70% of the test is conceptual questions, most of which are not found in the notes in any place, and are not covered in class at all...quite honestly, most of optics is very poorly taught, and I have seen that I am not alone in that opinion at all...
My weak advice: Get an outside source that lays out the concepts that you are covering (I used an old physics text), and memorize the concepts from that. The materials you get in class do prepare you well for the actual calculations....good luck, I'm gonna need it too
