Physics 2010 JAMB Past Questions - Question 31: Which of the following is used for the correction of short-sightedness ?

Correct Answer

A

Explanation

Short-sightedness, also known as myopia, can be corrected with various methods. The most common methods for correcting short-sightedness include:

1. **Eyeglasses:** Prescription eyeglasses with concave (diverging) lenses are used to help focus light properly on the retina, which reduces the blurriness associated with myopia.

2. **Contact Lenses:** Contact lenses are another option for correcting myopia. Like eyeglasses, they use concave lenses to adjust the way light enters the eye.

3. **Refractive Surgery:** There are several types of refractive surgery, with the most popular being LASIK (Laser-Assisted In Situ Keratomileusis). These surgeries reshape the cornea to correct vision, often reducing or eliminating the need for glasses or contact lenses.

4. **Orthokeratology (Ortho-K):** This involves wearing special rigid contact lenses overnight, which temporarily reshape the cornea to correct myopia during the day.

The choice of correction method may depend on factors such as the severity of myopia, personal preference, lifestyle, and consultation with an eye care professional.
