Optics Clinical Calculator app review 2021



If you work in the field of optometry then you probably deal with a lot of calculations, so Optics Calculator app for iPhone has been designed to make it quicker and easier than ever to perform these calculations more or less automatically.

This is definitely a pretty niche eyesight app so I don’t imagine there is a lot of competition; however, this doesn’t seem to have prevented the developer from going the extra mile and making an optometrist app that is actually a real pleasure to use; if only I had a clue what the terms actually meant!

Continue reading our review to see how this app compares to the best iPhone apps for eyesight.

Opticians Rejoice

In all honesty, a lot (most) of the terms used in this optometry iOS app go way over my head, so here’s a quick rundown of the calculations that are included:

  • Base Curve
  • Convergence
  • Diopter to/from Radius (mm) Conversion
  • Diopters from Focal Distance
  • Intermediate and Near Vision Prescriptions from Standard Refraction
  • Lens Power in Oblique Meridians
  • Oblique Crossed Cylinders
  • Ocular Curve
  • Optical Center Decentration
  • Slab-Off calculator (Induced Prism)
  • Vertex Distance

Some of these can be adjusted with the graphical interface by spinning wheels or dials to get the figures you need.

Final Words

Optics Clinical Calculator for iPhone and iPad makes a fantastic addition to the Medical category of the App Store, and I’d really like to commend the developer for putting in the effort required to pull off a technical utility like this.
