ahhh--an ophthalmologist ffiend of mine gave me a full Phoroper to "play with"...I can now "do" my own refractions literally check to see the proper prescription was given to me (or anyone else)!!!!!
This is t he large device (with the 30 knobs and hundreds of lenses) the doctor places before your eyes while asking yuou to read the letter charts...it gives the needed refrqctory, cylidrical etc corrective changes needed to attempt to restore your vision to (or as close as possible to-) 20/20 as possible.
cant wait to check my most recent prescription accuracy!!
ive found it is good practice to actually "check" your intended presription while looking out a window (vs looking at the eyechart in the office)--as-looking out the wibndow is a "real life" visual application (vs loking at an eye chart...)....thuis can be done using a trail frame....
