Optics you
can move.
A plug-and-play library of interactive optics sandboxes for ophthalmology. Open one, drag the parameters, and watch the physics respond — from your first lecture to the operating room.
One loop, every time.
No account, no syllabus, no order to follow. Open any sandbox and you’re already doing all four.
Open
Pick a sandbox. Each one is a single, standalone optics problem.
Drag
Grab the object, the lens, the streak. Every parameter is in your hands.
Watch
The physics responds in real time — image, vergence, power, all live.
Check
Type your own numbers to check your work, then share the exact state by link.
Start with these.
Four domains, one flat library.
Four ways to find a sandbox, not four levels. Open a domain to narrow the list, then dive into whatever you want.
One sandbox, the whole spectrum.
There are no beginners or experts here — only the optics and whatever you’re trying to work out. A first-year medical student and a cataract surgeon open the very same sandbox.
The student
Just saw thin lenses on a slide. Drag the object across the focal point and watch the image flip — the concept finally lands.
The resident
Unsure on a transposition between patients. Type the numbers into the power cross and see, in seconds, whether they check out.
The fellow
Pushing a multi-lens system to its edges to build intuition for where the simple model starts to break down.
The surgeon
Brushing up on the vergence that drives an IOL formula — no course to wade through, just the optics.
A sandbox you drop into. Every module is one standalone, physically-correct simulation — open it, move the controls, and the optics responds in real time. Type your own numbers to check your work, and share the exact state with a link.
Not a course, not a quiz bank, not a marketing simulator, and not sorted by training level. Just one flat library you can open in any order, as often as you like.
Start with Thin Lenses.
Drag the object across the focal point and watch the image flip. It’s the fastest two minutes in optics.
