Eye : Myopia :: Teeth : ?

Pyorrhoea
Cataract
Trachoma
Eczema

The answer is pyorrhoea.

Myopia is a condition in which a person can see objects that are close to them clearly, but objects that are far away appear blurry. Pyorrhoea is a condition in which the gums become inflamed and infected. This can lead to tooth loss.

Cataract is a clouding of the lens in the eye. This can make it difficult to see. Trachoma is a bacterial infection of the eyes that can cause blindness. Eczema is a skin condition that can cause itching, redness, and flaking.

Pyorrhoea is the correct answer because it is a condition

that affects the teeth, just as myopia is a condition that affects the eyes. The other options are not correct because they are not conditions that affect the teeth.
