A glasses prescription without astigmatism typically does not include a Cylinder (CYL) value. A negative sign (-) indicates nearsightedness. A positive sign (+) or no sign suggests farsightedness. Check the sphere (SPH) value for the overall lens power, which shows the prescription components for vision correction.
The sphere value indicates the degree of nearsightedness or farsightedness. A negative number signifies myopia, while a positive number indicates hyperopia. Higher absolute values reflect a stronger prescription.
Understanding your glasses prescription without astigmatism is crucial for choosing the right lenses. By knowing this information, you can ensure that your vision is corrected effectively. The right prescription leads to clearer vision and improves daily tasks like reading or driving.
