Long And Short Sight Flashcards
People with long sight cannot focus on
Nearby objects
People with long sight can easily focuse on things in
The distance
With long sight the near point is further than
25cm
Having an eye ball that’s to short will mean you have
Long sight
If the lens becomes less elastic you have
long sight
Long sight is treated using what type of lens
Convex or converging lens
In Short sight the what is closer than in normal people’s sight
Far point
If the eye ball is too long you have
Short sight
Short sight is also caused when the
Lens is to thick
Short sight can be treated by using a
Concave diverging lens
We can decrease the focal length of a lens by
Increasing the thickness (curvature) of the lens
Increasing the refractive index of the lens will
Decrease the focal length of a lens
I long sight light is focused
Behind the retina
In short sight light is focused
Infringe of the retina
