A Spherical Equivalent is an estimate of your eyes’ refractive error, calculated independently for each eye. It is calculated by merging the spherical (nearsightedness or farsightedness) and cylindrical (astigmatism) components of your refractive error but is usually not accurate enough for ordering glasses that would provide the sharpest vision.Left: 0.50/2 + (-2.50) = -2.75Right: 0.50/2 + (-2.00) = -2.25
