    Solution:

    Concept: Symptoms include headaches, eyestrain, difficulty to read fine text, and the need to space reading material farther apart. There would be differing degrees of difficulty for different people. Presbyopia is a typical aspect of becoming older. It might be accompanied by other types of refractive abnormalities.
    When seeing close objects, the eye might focus light behind the retina instead of on the retina due to age-related changes in the lens (decreased flexibility and increased hardness). It is a kind of refractive error, along with nearsightedness, farsightedness, and astigmatism. The diagnosis is made through an eye examination.
    Symptoms include difficulty seeing tiny text, the need to space reading items farther apart, headaches, and eyestrain. The degree of difficulty would differ amongst people. Presbyopia is a typical aspect of ageing and may be present in conjunction with other refractive abnormalities.
    The ability of the eye to focus light behind the retina rather than on it while seeing close objects is a result of age-related changes in the lens (decreased flexibility and increased hardness) and ciliary muscle power. This type of refractive defect includes astigmatism, nearsightedness, and farsightedness. To make the diagnosis, an eye examination is used.
    Presbyopia can be reversed with the use of glasses, contacts, multifocal intraocular lenses, LASIK surgery, and more. The best method of correction is glass with a suitably convex lens. Presbyopia can also be treated using clear reading glasses, bifocals, trifocals, and progressive lenses.
    Hence, option 4 is the correct answer.
