The signs and symptoms of Myopia include
- A.
Primarily distance blur
- B.
Improved vision with squinting
- C.
Asthenopia
- D.
Difficult with near vision
- E.
Photophobia
Correct Answer(s)
A. Primarily distance blur
B. Improved vision with squinting
C. AsthenopiaExplanation
The signs and symptoms of Myopia include primarily distance blur, improved vision with squinting, and asthenopia. Primarily distance blur refers to the difficulty in seeing objects that are far away clearly. Improved vision with squinting is a common behavior in individuals with myopia as it temporarily changes the shape of the eye, allowing for better focus. Asthenopia refers to eye strain or fatigue, which can be experienced by individuals with myopia due to the constant effort required to focus on objects.Rate this question:

When using trial frames to show a patient their new trial frames, it is important to show them binocular changes.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When using trial frames to show a patient their new trial frames, it is important to show them binocular changes. This means that both eyes should be considered together, rather than just focusing on one eye at a time. By showing binocular changes, the patient can get a more accurate representation of how their vision will be improved with the new trial frames.Rate this question:

The most common form of myopia is
- A.
Youth onset
- B.
Congenital
- C.
Early adult onset
- D.
Late adult onset
Correct Answer
A. Youth onsetExplanation
The most common form of myopia is youth onset. This means that myopia typically develops during childhood or adolescence. This is supported by research that shows that myopia tends to progress during the school years and stabilize in early adulthood. Congenital myopia, on the other hand, is present at birth and is relatively rare. Early adult onset and late adult onset myopia are less common than youth onset myopia.Rate this question:

Conventional Myopes will progress whether or not you prescribe.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is suggesting that individuals with conventional myopia will continue to experience progression of their condition regardless of whether or not they are prescribed corrective measures. In other words, even if they are given glasses or contact lenses, their myopia will still worsen over time.Rate this question:

Which of the following are factors to consider when prescribing for myopia, according to Dr. Myung Lee?
- A.
Near work - what does the patient spend their day doing?
- B.
Patient comfort
- C.
Myopic progression
Correct Answer(s)
A. Near work - what does the patient spend their day doing?
B. Patient comfort
C. Myopic progressionExplanation
When prescribing for myopia, Dr. Myung Lee suggests considering three factors. The first factor is near work, which refers to the activities the patient engages in throughout the day. This is important because certain near work activities, such as reading or using digital devices for long periods, can contribute to myopia progression. The second factor is patient comfort, which involves ensuring that the prescribed treatment or corrective measures are comfortable for the patient to use. Lastly, myopic progression is another crucial factor to consider, as it pertains to the rate at which the patient's myopia is progressing and may influence the choice of treatment or prescription.Rate this question:

What are the subcategories for Progressive myopia?
- A.
Transient pseudomyopia
- B.
Cyclic adaptation
- C.
Conventional
- D.
Congenital
- E.
High
Correct Answer(s)
A. Transient pseudomyopia
B. Cyclic adaptationExplanation
Progressive myopia is a condition where a person's nearsightedness worsens over time. It can be categorized into different subcategories based on the specific characteristics of the condition. Transient pseudomyopia refers to a temporary form of myopia that occurs due to factors such as excessive near work or prolonged focusing on close objects. Cyclic adaptation refers to a pattern of myopia progression that occurs in cycles, with periods of rapid progression followed by periods of stability. These two subcategories are the correct answers to the question.Rate this question:

In general, there is an even distribution of hyperopes and myopes in the population.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement suggests that there is an equal number of hyperopes (people with farsightedness) and myopes (people with nearsightedness) in the general population. This means that the prevalence of these two common refractive errors is balanced, indicating that neither condition is more prevalent than the other.Rate this question:

Which of the following optical elements can result in myopia
- A.
Increase in the index of refraction of the aqueous
- B.
Decrease in the index of refraction of the aqueous
- C.
Decrease in the index of refraction in the lens cortex
- D.
Decrease in the index of refraction of the vitreous
- E.
Increase in the index of refraction of the vitreous
Correct Answer(s)
A. Increase in the index of refraction of the aqueous
C. Decrease in the index of refraction in the lens cortex
D. Decrease in the index of refraction of the vitreousExplanation
An increase in the index of refraction of the aqueous humor, a decrease in the index of refraction in the lens cortex, and a decrease in the index of refraction of the vitreous humor can all result in myopia. The index of refraction determines how much light is bent as it passes through a medium. In myopia, the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina instead of directly on it. By altering the index of refraction in different parts of the eye, the overall refractive power of the eye can be changed, leading to myopia.Rate this question:

Myopia can be due to an eye having a _____ axial length
Correct Answer(s)
LongerExplanation
Myopia, also known as nearsightedness, is a condition where a person can see objects that are close to them clearly, but objects that are far away appear blurry. This occurs when the axial length of the eye is longer than normal. The longer axial length causes light to focus in front of the retina instead of directly on it, resulting in blurred distance vision. Therefore, the correct answer is "Longer."Rate this question:
- 20.
Myopia can be due to an eye having a _____ corneal curvature
Correct Answer(s)
SteeperExplanation
Myopia, also known as nearsightedness, is a refractive error of the eye where distant objects appear blurry. It occurs when the cornea, the clear front surface of the eye, has a steeper curvature than normal. This causes the light entering the eye to focus in front of the retina, instead of directly on it. As a result, the image formed on the retina is out of focus, leading to nearsightedness. Therefore, a steeper corneal curvature can be a possible cause of myopia.Rate this question:
