1.
What is another name given to myopia?
Correct Answer
B. Nearsightedness
Explanation
Myopia is another name for nearsightedness. It is a common vision condition in which close objects appear clear, but distant objects appear blurry. This occurs when the eyeball is slightly longer than usual or when the cornea is too curved. As a result, light entering the eye is focused in front of the retina instead of directly on it, causing distant objects to appear blurred. Therefore, the correct answer is nearsightedness.
2.
Who treats the myopia defect?
Correct Answer
A. OpHthalmologist
Explanation
An ophthalmologist is a medical doctor who specializes in the diagnosis and treatment of eye diseases and disorders. Myopia, also known as nearsightedness, is a common eye condition where objects up close appear clear, but distant objects appear blurry. An ophthalmologist is trained to provide comprehensive eye care, including prescribing glasses or contact lenses to correct myopia, as well as performing surgical procedures such as LASIK to permanently correct the condition. Therefore, an ophthalmologist is the correct professional to treat the myopia defect.
3.
Which of these is odd?
Correct Answer
C. Colour blindness
Explanation
Colour blindness is the odd one out because it is the only condition that affects the perception of color. Glaucoma, cataract, and retinal detachment are all eye conditions that can cause vision problems, but they do not specifically affect color perception.
4.
Which category of people is affected through spending much time indoors?
Correct Answer
A. Children
Explanation
Children are the category of people who are affected through spending much time indoors. This is because children require physical activity and exposure to sunlight for their overall growth and development. Spending excessive time indoors can lead to a sedentary lifestyle, lack of exercise, and limited social interaction, which can have negative effects on their physical and mental health.
5.
Which of these is a symptom of myopia?
Correct Answer
A. Eye strain
Explanation
Eye strain is a common symptom of myopia, also known as nearsightedness. Myopia is a refractive error of the eye where distant objects appear blurry, while close objects can be seen clearly. This condition often leads to eye strain because the eyes have to work harder to focus on objects that are far away. This can cause discomfort, headaches, and fatigue. Therefore, eye strain is a symptom that is commonly associated with myopia.
6.
Which diagnostic method is used in treating myopia?
Correct Answer
A. Eye exam
Explanation
Eye exam is the correct answer because it is the diagnostic method used in treating myopia. Myopia, also known as nearsightedness, is a refractive error of the eye that causes distant objects to appear blurry. An eye exam involves various tests to assess the visual acuity and determine the extent of myopia. This includes reading an eye chart, using a phoropter to determine the prescription for corrective lenses, and examining the health of the eye. Based on the results of the eye exam, appropriate treatment options can be recommended, such as glasses, contact lenses, or refractive surgery.
7.
Which of these is not a cause of myopia?
Correct Answer
A. Smoking
Explanation
Smoking is not a cause of myopia. Myopia, also known as nearsightedness, is primarily caused by genetics. It is a refractive error where the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina instead of on it. Exposure to light, particularly sunlight, has been suggested to have a protective effect against myopia development. However, excessive near work and prolonged time spent indoors have been associated with an increased risk of myopia.
8.
Which of these countries is mostly affected by myopia?
Correct Answer
B. United States
Explanation
The United States is mostly affected by myopia because it has a high prevalence of nearsightedness among its population. This could be attributed to various factors such as lifestyle changes, increased use of digital devices, and limited outdoor activities. Additionally, the United States has a well-developed healthcare system that allows for early detection and diagnosis of myopia, leading to higher reported cases compared to other countries.
9.
Which category of people is mostly affected by myopia?
Correct Answer
C. Children
Explanation
Children are mostly affected by myopia because their eyes are still developing and growing. Myopia, also known as nearsightedness, occurs when 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. This makes distant objects appear blurry. Children's eyes are more prone to elongation and changes in shape, which can contribute to the development of myopia. Additionally, excessive near work and prolonged screen time, which are common among children, can also increase the risk of myopia.
10.
Which of these is odd?
Correct Answer
D. Eye Strain
Explanation
Eye Strain is the odd one out because it is not a specific eye condition like the other options. Retinal detachment, cataract, and glaucoma are all eye conditions that can cause vision problems and require medical intervention. Eye strain, on the other hand, is a common condition that is caused by prolonged use of digital devices or reading in poor lighting conditions, resulting in discomfort and temporary vision problems.
