graph points to rememberrrrrrrrrr Flashcards
what is the peak of rhodopsin? (rod spec sensitivity)
507nm
what are the peaks of the 3 pone pigments and their combined peak? (cone spec sensitivity)
L: 565nm
M: 535nm
S: 430nm
combined: 555nm
what are the points in wavelength to rmb for photochromatic interval?
350nm- just before 650nm
at 650nm
after 650nm
what are the points in time to rmb for DA curve
0-10min: cone branch ~10-12 min: cone plateau (absolute threshold) ~12 min: rod cone break 12-35 min: rod branch tail: rod plateau (absolute threshold)
what are the peaks for cone spec in CVD? (hint there is no set number)
normal: 555nm
protanopia: shorter nm
deuternopia: longer nm
tritanopia: 555nm but at lower sensitivity
at what wavelengths do protanopes and deutanopes have good and bad hue disc?
good at 490nm
none beyond 545nm
at what wavelengths do tritanopes have good and bad hue disc?
good: longer nm
none at 495nm
what are the saturation neutral points for protanopes, deutanopes and tritanopes? what to note for anomalous defects?
protanopes: 492nm
deutanope: 498nm
tritanopes: 569nm
protanomaly and deutanomaly have same points but abnormal saturation perception at these points
