A person went for a medical check-up and found that the curvature of his eye lens is increasing. Which of the following defects is he likely to suffer from?

The increase in the curvature of the eye lens is typically associated with a condition known as "myopia" or nearsightedness. Myopia occurs when the eye is longer than normal or the lens is too curved, causing light rays to focus in front of the retina rather than directly on it. This results in difficulty seeing distant objects clearly while near objects may be seen without issue. The curvature of the lens can change with age or due to environmental factors, leading to an increase in this condition.

In summary, given that the curvature of the eye lens is increasing, the person is likely to suffer from myopia. This condition highlights the importance of regular eye examinations to monitor changes in vision and to take appropriate measures such as corrective lenses or other interventions.
