For example: if your present contact lens power is actually + 1.75 D, the next more powerful power lens readily available will definitely be + 2.00 D.

The power of the contact lens that fix nearsightedness is preceded through the minus (-) sign, whereas in the case of farsightedness, the power is actually anticipated through the additionally (+) indicator. The smooth circular single dream contact lenses that have the power of - 1.50 D right 1.50 diopters of nearsightedness. The power goes to times, signified as - 2.50 sph, or even clearly - 2.50.

Soft Toric Single Vision Lenses - These smooth contact lens are actually made use of for the correction of astigmatism, in combo along with either farsightedness, and/or with nearsightedness.
