The correct option is B a, c and d
Sometimes, the eye may lose its power of accommodation. In such cases, the vision becomes blurred due to the refractive defects of the eye. Three common refractive defects of vision are myopia or near-sightedness, Hypermetropia or farsightedness and Presbyopia.
A cataract is a clouding of eye lenses. it is denser so eyes make blurred images on the retina.
