Final answer:
The age-related loss of close vision is called presbyopia. It is commonly corrected with converging lens glasses, and even after LASIK surgery, reading glasses may still be necessary.
Step-by-step explanation:
The age-related loss of close vision is known as presbyopia. Presbyopia is a common vision problem that ocurs as people age, and it involves the gradual loss of the eye's ability to focus on nearby objects. The cause is typically attributed to a decrease in the elasticity of the lens or weakening of the eye muscles responsible for focusing. People generally begin to notice symptoms, such as difficulty reading small print or eyestrain, between the ages of 40 and 50. To correct this issue, corrective lenses with a converging lens are commonly used, which add power for close vision. Even if a person with presbyopia has LASIK surgery to correct their distant vision, they may still need reading glasses to compensate for their inability to focus on close objects.
