I'm currently studying Chapter 6 of one of my books(Kaplan preparation) which is physiological integrity, specifically the section on impaired vision like Myopia, Hyperopia, etc et.
My concern, I'm confused about myopia and hyperopia. "Light rays refract at a point in front of the retina(myopia) and behind the retina(hyperopia). Anyone have a good explanation for what refracting is in relation to the light rays? I looked up refract in the medical dictionary but I can't picture it.
Post your concerns and progress on the subject that your currently studying in this thread if you will!:nuke:

Im currently studying saunders compre 3rd ed, chapter 61 "Renal System."
myopia- nearsightedness, rays coming from an object are focused in front of the retina.
Im a myopic and my optometrist said that myopic have oval eyeballs. This is why light rays cant reach the retina. This is also why we need biconcave lens
hyperopia- farsightedness, objects converge to a point behind the retina.
They have a little bit flat eyeballs that is why light rays pass through the retina and are focused behind the retina. They need convex lens.
MNEMONICS: FARVEX -farsighted, biconvex lens
NEARCAVE - nearsighted, concave lens
Hope you can picture out now! It could have been better if there's a drawing but i cant...

I'm planning to take the NCLEX at the end of April. Have finished most of the Saunders 4th Edition CD and am starting the set of Pharm questions.:typing Also, just received the NCLEX review 4000 by Wolters Kluwer, Lippincott, Williams & Wilkins...it's the latest. (I read that Lippincott is teaming up with Kaplan for NCLEX training) Will construct some tests with this CD and see how I score. Keep studying guys...practice is gonna make perfect!
