The first dimension you need to consider is the diameter of your contact lens, which refers to its size measured from one side of the lens to the other. Typically, standard lenses have diameters ranging between 13mm to 16mm. A larger DIA tends to provide a more natural feel and better peripheral vision.
Next is the central thickness, which refers to the thickest part of the lens where it meets the center of the eye. Lenses come in varying thicknesses based on their purpose:

Standard thickness lenses have a central thickness between 0.2mm to 0.35mm and offer good balance between comfort and performance.

The working tolerance refers to the lens's flexibility or ability to conform to the curvature of your eye without causing discomfort or compromising vision quality. A lower WT means less flexibility but better stability on the eye.
