1.
Which of the following is not a symptom of myopia?
Correct Answer
A. Stomach ache
Explanation
Myopia, also known as nearsightedness, is a condition where distant objects appear blurry while close objects can be seen clearly. The symptoms of myopia include blurred vision of distant objects, headaches, and eye strain. However, stomach ache is not a symptom of myopia. It is important to consult an eye care professional for a proper diagnosis and treatment of myopia.
2.
Which of the following cannot cure the disorder?
Correct Answer
D. Blowing air thw eye
Explanation
Blowing air into the eye cannot cure the disorder because it does not address the underlying cause of the disorder. Eyeglasses, contact lenses, and surgery are all potential treatments for certain eye disorders as they aim to correct vision problems or address structural issues within the eye. However, blowing air into the eye does not have any therapeutic effect and therefore cannot cure the disorder.
3.
Which field is concerned with the disorder?
Correct Answer
B. OpHthalmology
Explanation
Ophthalmology is the field concerned with disorders related to the eyes. It focuses on the diagnosis, treatment, and prevention of eye diseases and disorders. This field deals with conditions such as cataracts, glaucoma, macular degeneration, and other vision impairments.
4.
Which of the following plays a pivotal role in establishing your chances of having this problem?
Correct Answer
A. Hereditary
Explanation
Hereditary factors play a pivotal role in establishing the chances of having this problem. This suggests that the problem in question is likely to be influenced by genetic factors passed down from one's ancestors. The other options, such as playfulness, low sugar level, and close contact with light, do not seem to be relevant or have a direct impact on the likelihood of experiencing this problem.
5.
What is the full meaning of PRK?
Correct Answer
A. pHotorefractive keratectomy
Explanation
PRK stands for Photorefractive keratectomy. This is a type of laser eye surgery that is used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. During the procedure, the surgeon uses a laser to reshape the cornea, improving the way the eye focuses light onto the retina. This surgery is an alternative to LASIK and is commonly used when the patient has thin corneas or other factors that make them unsuitable for LASIK.
6.
Which of the following does LASIK not help in correcting?
Correct Answer
D. Relp
Explanation
LASIK is a surgical procedure that corrects refractive errors in the eye, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. However, "Relp" is not a recognized refractive error, so LASIK cannot help in correcting it.
7.
How many minutes does LASIK take to be performed?
Correct Answer
A. 15mins
Explanation
LASIK (Laser-Assisted in Situ Keratomileusis) is a surgical procedure used to correct vision problems. It involves using a laser to reshape the cornea. The correct answer is 15 minutes because LASIK typically takes a short amount of time to perform. The procedure itself usually only takes around 10-15 minutes per eye. This quick procedure time is one of the reasons why LASIK is a popular choice for vision correction.
8.
Which of the following does not help in managing myopia?
Correct Answer
D. Sleeping
Explanation
Sleeping does not help in managing myopia. Myopia, also known as nearsightedness, is a refractive error where distant objects appear blurry. Eyeglasses, orthokeratology lenses, and LASIK are all methods commonly used to manage myopia by correcting the refractive error in the eye. However, sleeping does not have any direct impact on the progression or management of myopia. While adequate sleep is important for overall eye health, it does not specifically address myopia.
9.
What stage of life does nearsightedness begin?
Correct Answer
C. Childhood
Explanation
Nearsightedness, also known as myopia, typically begins during childhood. This condition causes difficulty in seeing objects clearly at a distance while close objects remain clear. It is caused by the elongation of the eyeball, resulting in the light focusing in front of the retina instead of directly on it. The onset of nearsightedness often occurs during school-age years and may progress throughout adolescence. Regular eye exams and corrective lenses are commonly used to manage nearsightedness in children.
10.
What does LASIK mean?
Correct Answer
A. Laser in-Situ Keratomileusis
Explanation
LASIK stands for Laser in-Situ Keratomileusis. It is a surgical procedure used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. During the procedure, a laser is used to reshape the cornea, improving the way light is focused onto the retina. This can result in clearer vision without the need for glasses or contact lenses.
