Bits & Pieces Flashcards
1
Q
Define Accomadaiton
A
Focussing CLOSE UP So: -> Parasympathetic Innervation -> Contraction of ciliary muscle -> Relaxes suspensory ligaments -> Less tension on lens -> Lens shortens and fattens -> Greater bending of light -> Focusses close up
2
Q
What lens would be used to correct hyperopia vs myopia?
A
Hyperopia (longsightedness)
- Image focusses behind retina
- > Convex lens to increase bending of light
Myopia (Shortsightedness)
- > Image focusses in front of retina
- Concave Lens to reduce bending
