Refractive Status

Question 1

Hypermetropia farsighted refractive error in which the point of focus for rays of light from distant objects is behind the retina ( correctable with a convex lens ) plus lens - farsighted

Answer 1

Hyperopia

Question 2

Nearsighted refers to refractive error in which the point of focus is in front of the retina eyes are in focus for near objects but cannot see a distant object clearly correctable with concave/ minus lens

Answer 2

Myopia

Question 3

A distortion of the curvature of the cornea or asymmetry of the components of the eye such that rays from a single pt are not focused at a single point on the retina. Light falls on the retina distorted and meets at various distances in front or behind the retina. Light falls on the retina distorted and meets at various distances in front or behind retina

Answer 3

Astigmatism

Question 4

Decreasing ability due to age of the lens of the eye to focus for near objects age related far sightedness plus lenses readers used to help

Answer 4

Presbyopia

Question 5

Opthalmic device -plus lens compensates for this condtion

Answer 5

Hyperopia
