New Oblique Cross Cylinders Calculator

Oblique Cross Cylinders


Hello all! I've been working on a new version of the oblique cross cylinders calculator and I thought it was time to introduce it to you.

Of course, the underlying math and optics of these calculations haven't changed. However, I thought it was time to give the calculator a facelift for several reasons.

The universal search bar

I picture EyeDock as a lot of things, but it’s main purpose has always been to be something of a search engine for all things related to eye care. While it’s never going to be the next Google, I’m sure going to try my darndest to come as close as an optometrist/programmer can.

I’ve had a “universal search” bar at the top of this site for quite a long time. It has always been used to search many of the databases on EyeDock, but I’ve recently made some enhancements that make it much more powerful. 

And, as always, I’m hoping this is another step in achieving my primary goal: To help our fellow eye care providers find information as quickly as possible

Why contact lens data in EMRs is taking a while

I recently wrote a blog post about how I would like to see contact lens data and calculations integrated into EMRs. I even went so far to create a little mockup of how it could work.

My intention was to create a concept piece - an idealized look at what the future might, or should, hold for us EMR-using ODs in the trenches.

I’ve received some great feedback from people expressing their frustration that these dreams are not a reality. As a person who has been brainstorming about how this could work for many years, I share that frustration.

However, my deep thinking on this subject has also given me some perspective on why things move slower than we’d like them to. As an optometrist who also writes software I can see both sides of this issue.

So, why can’t EMRs do more fancy things like better integrate contact lens data?
