Smooth spheric singular dream contact lenses are actually made in the power increments of 0.25 D. For instance: if your current contact lens power is + 1.75 D, the following more powerful power lense offered will be actually + 2.00 D.
The power of the contact lens that improve nearsightedness is preceded by the minus (-) indication, whereas in the situation of farsightedness, the power is come before due to the plus (+) indicator. The smooth circular solitary dream contact lenses that possess the power of - 1.50 D appropriate 1.50 diopters of nearsightedness.
