Glasses to Contacts Converter is a great tool for converting glasses prescriptions to contact lens prescriptions. If you’re trying to do a contact lens fitting and don’t have time to perform a vertex conversion, this program will recommend a prescription for you. This tool is a great time-saver for clinicians and students who don’t have time to do the math.

Unlike most vertex conversion utilities, this program takes into account various limitations when performing contact lens fittings. Examples of some of these considerations include:

  • Recommending a spherical equivalent for cyclinder under -0.50 diopters
  • Taking into account the fact toric lenses start at -0.75 diopters and continue in -0.50 diopter increments
  • Rounding the axis to the nearest tens toward the closest major axis (90 or 180)

An additional and brand new feature added to the program is that it makes contact lens brand suggestions using filters such as replacement schedule, cost, astigmatism, presbyopia and the need for extended wear.

The best part about the program is that it is 100% free to use. No subscription or purchase is required; don’t mind the non-intrusive ad though =)

Disclaimer: This program was made for educational purposes only. Do not try to order contact lenses without a valid prescription. The brand suggestions are also merely suggestions and do not take the place of medical advice.
