Contact Lens Math Formula. The formula for converting a glasses prescription to contact lenses is simple. A calculator to quickly and easily convert spectacle rx to a contact lens rx and its spherical equivalent. We can use this formula to solve for f2 whether it is from spectacle rx to contact lens rx, or vise versa. In part 1, part 2 and part 3 of this tutorial series, you learned all about how lenses work, why prescriptions for glasses are sometimes different than prescriptions for contact lenses, and how to calculate a. It is called the back vertex formula and it. As a major throwback to optics 101, you may remember this formula: You can round the values calculated above to the nearest 0.25 d to obtain the closest lens. Often used to calculate the power of a contact lens given the. For eyeglass lenses, most eye care practitioners use a standard vertex distance of 12 millimeters (mm) from the cornea. Since a contact lens sits directly on the eye, we consider the vertex. Simple online tool to compensate lens power for changes in back vertex distance.
