Optician Flashcards

Front 1

Accommodation

Back 1

Focusing of the eye on a near object through relaxation of the ciliary muscle and thicking of the lens.

Hint 1

I can read the newspaper because of this.

Front 2

Amblyopia

Back 2

The loss of vision without any apparent disease of the eye.

Hint 2

You don't know why I lost my vision?

Front 3

Ametropia

Back 3

A refractive error in which the eye, when in a state of rest, does not focus the image of an object upon the retina; include hyperopia, myopia, and astigmatism.

Hint 3

Why I can't see.

Front 4

Aniseikonia

Back 4

A condition in which the ocular image of an object as seen by one eye differs so much in size or shape from that seen by the othere eye that the two images cannot be fused into a single impression.

Hint 4

How many fingers am I holding up?

Front 5

Anisometropia

Back 5

A condition in which the refractive error of one eye significantly differs from that of the other; each eye must have the same sign, i.e. both eyes are myopic or hyperopic.

Hint 5

one is bad, the other, worse.

Front 6

Antimetropia

Back 6

The refractive condition whereby the signs in each eye are opposite; one eye is hyperopic and the other myopic.

Hint 6

Monovision, naturally.

Front 7

Aphakia

Back 7

An absence of the crystalline lense of the eye.

Hint 7

I had that here a minute ago!

Front 8

Aqueous humor

Back 8

The clear water fluid that fills the anteiror and posterior chambers within the front part of the eye.

Hint 8

Eye ocean

Front 9

Astigmatism

Back 9

A refractive error that prevents the light rays from coming to a single focus on the retina because of different degrees of refraction in the various meridians of the eye.

Hint 9

A cylinder on the eye.

Front 10

Cataract

Back 10

A condition in which the crystalline lens of the eye, or its capsule, or both, become opaque, with consequent loss of visual acuity.

Hint 10

The eyes of an old dog

Front 11

Choroid

Back 11

The vascular intermediate coat that furnishes nourishment to other parts of the eyeball.

Hint 11

I'm hungry, says the eyeball.

Front 12

Ciliary Body

Back 12

That portion of the vascular coat between the iris and the choroid. It consists of the ciliary processes and the ciliary muscle.

Hint 12

Part of the muscle coat

Front 13

Compound Hyperopic Astigmatism

Back 13

The refractive error which results in two points of focus falling behind the retina.

Hint 13

Two points behind the eye ball

Front 14

Compound myopic astigmatism

Back 14

The refractive error which results in two points of focus falling in front of the retina.

Hint 14

Two point, before eye ball

Front 15

Cornea

Back 15

The clear transparent portion of the outer coat of the eyeball forming the covering of the aqueous chamber.

Hint 15

Clear outer coat

Front 16

Crystalline Lens

Back 16

A transparent colorless body suspended in the front part of the eyeball, between the aqueous and the vitreous, the function of which is to bring the rays of light to a focus on the retina.

Hint 16

The big magnifier.

Front 17

Diplopia

Back 17

The seeing of one object as two.

Hint 17

Wow, you didn't tell me you had a twin!

Front 18

Emmetropia

Back 18

The refractive condition of the normal eye, when the eye is at rest, the image of distant objects is brought to a focus on the retina.

Hint 18

20/20

Front 19

Fovea

Back 19

A small depression in the retina at the back of the eye; the part of the macula adapted for most acute vision.

Hint 19

X marks the spot

Front 20

Fusion

Back 20

The power of coordination by which the images received by the two eyes become a single image

Hint 20

Where two become one.

Front 21

Glaucoma

Back 21

An ocular disease having as its primary characteristic a sustained increase in intraocular pressure that the eye cannot withstand without damage to its structure or impairment of its function.

Hint 21

Breaking under pressure

Front 22

Hyperopia

Back 22

A refractive error in which, because the eyeball is short or the refractive power of the lens is weak, the point of focus for rays of light from distant objects falls behind the retina; accommodation to increase the refractive power of the lens is necessary for distance vision as well as near vision.

Hint 22

Stop following me!

Front 23

Iris

Back 23

The colored circular membrane suspended behind the cornea and immdeidately in front of the lens. The iris regulates the amount of light entering the eye by changing the size of the pupil.

Hint 23

Lifesaver of sight

Front 24

Irregular astigmatism

Back 24

A refractive condition caused by a cornea which is damaged and irregular so that rays of light come to many focal points on the retina, is not correctable by cylinders.

Hint 24

traffic accident cornea

Front 25

Iseikonic lenses

Back 25

Spectacle lenses specially designed to manipulate image size when dissimilar sizes makes it difficult or impossible for fusion to occur; such as in aniseikonia.

Hint 25

Forcing two to become one

Front 26

Macula

Back 26

A small area of the retina that surrounds the fovea and that with the fovea, comprises the area of the retina that gives distinct vision.

Hint 26

Determines if you can see the last golf swing

Front 27

Mixed Astigmatism

Back 27

The refractive condition in which the light comes to two points of focus where one point is in front of the retina, and the other is behind the retina.

Hint 27

This astigmatism cannot make up its mind.
