A client is experiencing visual difficulties and has been told that a previous vision test showed that the light rays entering the eye are falling in front of the retina.
The nurse understands that this client is experiencing which of the following visual disturbances?
- a) Myopia***
- b) Hyperopia.
- c) Astigmatism.
- d) Exophthalmos.
The correct answer is a) Myopia.
Here's why:
- Myopia:
also known as nearsightedness, is a condition in which light rays entering the eye focus in front of the retina, causing distant objects to appear blurry. This occurs because the eyeball is elongated or the cornea is too curved.
- Hyperopia:
also known as farsightedness, is the opposite of myopia. In hyperopia, light rays focus behind the retina, making near objects appear blurry. This occurs because the eyeball is too short or the cornea is not curved enough.
- Astigmatism:
is a condition in which the cornea or lens is irregularly shaped, causing blurred vision at all distances.
Exophthalmos is a condition characterized by bulging eyes, which can be caused by various factors but does not directly relate to the focusing of light rays on the retina.
