Actulally if that happened you will not be able to see without specs
The lens of your eye is a double convex lens. Its job is to focus the image on the retina of the eye. If one is farsighted, the lens in the eye causes the focus to be behind the retina. These people see far but have some difficultly seeing close-up. The lens focuses behind the retina because the actual eyeball is too short from front to back. To correct this farsightedness, the person would wear glasses or contacts with convex lenses.
but if plain lenses are used in case of convex rays of light will not converge on retina as a result you will not able to see anything clearly

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
