A student has difficulty reading the blackboard while sitting in the last row. What could be the defect the child is suffering from? How can it be corrected?

Difficulty reading the blackboard from a distance could be indicative of various vision problems. One common vision issue that might cause this difficulty is nearsightedness, also known as myopia. Nearsighted individuals can see objects up close more clearly than those at a distance.

To correct nearsightedness, the student may need eyeglasses or contact lenses with a prescription that compensates for the refractive error. The corrective lenses diverge the light entering the eye, allowing distant objects, such as the writing on the blackboard, to come into focus.

It’s important for the student to undergo an eye examination by an optometrist or ophthalmologist to determine the exact nature of their vision problem and to prescribe the appropriate corrective measures. Regular eye check-ups are crucial to detect and address any changes in vision promptly.

If the vision problem is identified early and corrected with the appropriate lenses, the student should experience improved clarity in their distant vision and be able to read the blackboard more comfortably. Additionally, good lighting in the classroom and proper positioning can also aid in optimal visibility for all students.
