By degrees, you probably mean diopters. Degrees usually refers to the direction of astigmatism. Therefore, the person with -8.00 and -5.00 diopters has worse vision than the person with -3.75 and -4.00 diopters. The minus sign is used for myopia (nearsightedness), a plus sign would indicate hyperopia (farsightedness).
If im farsighted do i need glasses
why does it matter. but anyway he farsighted if you have to know
If it is written as +2 Diopters it is positive, ie a converging lens. If it is written as -2 Diopters it is negative, ie a diverging lens. Diverging lenses are prescribed for myopia, or short-sightedness. Converging lenses are prescribed for hypermetropia or long-sightedness.
he is a farsighted person because he can easily seen that thing which is far from him.
It means that you are farsighted. The scale starts at 0 and everything on the plus side is farsighted and everything on the minus side i nearsighted.
