Question Answer
The most common visual problem is ___________.
Show Answer
Refractive error
This visual defect prevents light rays from converging into a single focus on the retina...
Show Answer
Refractive errors (myopia, hyperopia, presbyopia, astigmatism, amblyopia and aphakia)
What are some causes of refractive errors? (3)
Show Answer
Corneal curvature, focusing power of the lens, or the length of the eye
Which type of refractive error is the most common?
Show Answer
Myopia (near-sightedness)
A client complains of blurred vision and a sensation of straining to see. He also states that he's been experiencing headaches lately. What is most likely going on?
Show Answer
He has a refractive error like myopia, presbyopia, etc. Blurred vision is the most common sign, followed by ocular discomfort, eye strain and headaches.
What is the difference between presbyopia and hyperopia?
Show Answer
Hyperopia is farsightedness, Presbyopia is farsightedness due to a decrease in the accommodative ability of the eye that results from aging.
________ is a condition that can develop in children with refractive errors that go uncorrected. It is characterized by reduced vision in the affected eye.
Show Answer
Amblyopia
Refractive errors in children don't produce further pathology (if uncorrected) after age _____.
Show Answer
6
_______ causes light rays to be focused in front of the retina and can be caused by excessive light refraction of the cornea or an abnormally long eye. There is an inability to accommodate for objects at a distance.
Show Answer
Myopia
_________ causes light rays to focus behind the retina and requires the patient to use accommodation to focus the light rays for near and far objects. This can occur when the cornea or lens doesn't have enough focusing power or when the eyeball is too short.
Show Answer
Hyperopia
________ occurs when the lens of the eye becomes larger, firmer and less elastic. The eye's accommodative abilities decrease and there's an inability to accommodate for near objects.
Show Answer
Presbyopia (starts to develop around age 45)
________ is caused by an abnormal corneal curvature and causes light rays to be bent unequally. The light rays don't come to a single point of focus on the retina. This can occur with any of the other refractive errors.
Show Answer
Astigmatism
The absence of the lens of the eye is called ________. It can occur congenitally or surgically (as with cataract surgery). This causes an image to be focused behind the retina.
Show Answer
Aphakia
What is functional aphakia?
Show Answer
A lens that is traumatically dislocated but still in the eye.

Show Answer

You have a client that wears contact lenses and is on birth control. What should you tell them?
Show Answer
Use of birth control pills may decrease tear production and cause discomfort while wearing contacts.
What types of medications can cause discomfort for people wearing contacts, and why?
Show Answer
Antihistamines, decongestants, diuretics, and birth control pills. They decrease tear production.
A client who is in her second trimester comes in complaining that her contacts have really started to hurt her eyes and she's wondering if she needs new ones. What do you tell her?
Show Answer
The hormones from pregnancy can cause decreased tear production and make wearing contact lenses uncomfortable.
What does the mnemonic RSVP stand for with respect to visual health?
Show Answer
Redness Sensitivity Vision Problems Pain (when to see a doctor for contact lens wearers)
What information should a nurse collect from patients that wear contact lenses?
Show Answer
