Farsighted for Two Diopters was created in 1976.
The duration of Farsighted for Two Diopters is 1.48 hours.
Ben Franklin, they are called bifocals
Diopters are a unit of measurement used to quantify the focusing power of a lens, which is important in optometry and ophthalmology. They indicate how much a lens converges or diverges light. Positive diopters indicate converging lenses (helps nearsightedness), negative diopters indicate diverging lenses (helps farsightedness), and zero diopters indicate no optical power.

If im farsighted do i need glasses
he is a farsighted person because he can easily seen that thing which is far from him.
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).
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.

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.
