Question

Imagine you have a doctor and you have to cure a patient who cannot see the distant objects clearly predict the distance and the treatment required

Answer 1

The disease is myopia, and treatment is the use of biconcave lens.

Explanation:

• Myopia is the disease in which individual can see close object clearly but cannot see distant object clearly
• myopia occur when eyeball is too long relative to the focusing power of lens or lens become thicken
• as a result image form in front of retina and distant object cannot be clearly seen
• using of biconcave lens causes light rays to diverge slightly, so that they are brought to a focus on retina
