This Is What the Pages You Will Study Look Like

One topic per page, the drawing that shows you how it's done and the boxes with what you need to know:

Tear film → cornea → aqueous → pupil → lens → vitreous → retina → optic nerve, numbered 1 to 8.

These are real pages from the book. The table of contents is the full one: 9 parts and 60 topics.

It's Not That You Have a Bad Memory. It's That Nobody Put It in Order.

You've read the workup chapter three times. You close the study guide...

...and you're not sure anymore if pupils come before or after the pinhole, or where pressure goes. It was just line after line.

History → acuity → pinhole → pupils → motility → fields → pressure → dilation if ordered.

Here the workup is one page, drawn as a sequence: history, acuity, pinhole, pupils, motility, fields, pressure, and dilation only if the doctor orders it.

And on the pages next to it, every test has its own: the swinging flashlight test, the cover test, confrontation fields, Goldmann applanation and the lensometer.

First you understand why it's done that way. Then the order sticks on its own.

SEE THE DIFFERENCE

Stop Memorizing Optics Formulas You Can't Picture:

THIS
  • Pages and pages of dense text
  • Optics formulas without a single drawing
  • On the exam, you don't know where to start
The diopter (D) is the unit of measurement of the refractive power of a lens and is defined as the reciprocal of the focal length expressed in meters (D = 1/f). Converging lenses are designated by a positive sign and diverging lenses by a negative sign. Accordingly, a lens of +2.00 D brings parallel rays of light to a focus at 0.50 m, whereas a lens of +4.00 D focuses at 0.25 m, the relationship between power and focal length being inversely proportional, such that any increase in dioptric power results in a correspondingly shorter focal distance.
FOR THIS
  • Every formula drawn
  • One topic per page, with the rules in boxes
  • You remember it because you've seen it
+2.00 D focuses at 0.5 m: D = 1 ÷ focal length in meters.

What If Every Topic Fit on a Single Page?

Picture this:

Instead of rereading half a page on transposition without being able to see it...

...you open the page and find the same lens drawn twice, once in plus cylinder and once in minus cylinder, with the three steps written right next to it.

Eyepiece, power wheel, axis wheel, lens stop, marking device: focus first, right lens first.

And the diopter, the swinging flashlight test, the six cardinal gazes, the lensometer and the cap colors turn into drawings and tables you read at a glance.

You stop repeating and start understanding.

That's what Ophthalmic Assistant Illustrated does: 64 illustrated pages in 9 parts, one topic per page. And at the end, the full workup checklist, the optics formulas and the normal values, each on one page.

Because what your brain sees organized, it remembers.

Frequently Asked Questions

How do I get the material?

You get an email with Ophthalmic Assistant Illustrated as a high-resolution PDF, to read on your phone or print. The two bonus books, Eye Workup Drills and Common Mistakes in the Eye Workup, come by email too.

Is it a monthly payment or a one-time payment?

One-time payment. No installments and no subscription.

Who is it for?

For ophthalmic assistants, technicians and scribes, for anyone preparing for the COA exam, and for medical assistants moving into eye care. It starts from the eye's anatomy, so you don't need a background in optics; if you've done the workup for years, it's a fast review in order. Check the table of contents above to see every topic.

What sources is it based on?

On the current COA exam content outline published by IJCAHPO, cross-checked against current American Academy of Ophthalmology references and CDC infection-control guidance for ophthalmic devices. The book is organized around the same areas the outline covers.

Is this official COA material?

No. It's an independent illustrated study book, not affiliated with or endorsed by IJCAHPO. It doesn't give a certificate or CE credits, and it doesn't count toward the COA eligibility requirements: it's a book to study and review with.

Does it replace my training or a COA prep course?

No. It's a visual review that goes alongside your training, your clinic's protocols and the doctor's instructions. It's study material, not medical advice.

Are the practice cases the real exam questions?

No. The drills and cases are written for this book. They aren't official exam questions: they're there to help you practice.

Can I print it?

Yes. It's a high-resolution PDF: print the whole book or just the pages you want to keep at your station.

What does the 30-day guarantee cover?

You have 30 days. If a file doesn't open, if the content isn't what this page describes, if you were charged twice or the email never arrived, write to us and we'll refund you in full.

You have 30 days: if a file doesn't open, if the content isn't what this page describes, if you were charged twice or the email never arrived, write to us and we'll refund you in full.

One Last Thing Before You Decide...

You don't have to reread the same page hoping it sticks this time.

You don't have to memorize optics formulas you can't picture.

And you definitely don't have to walk into the exam not knowing where to start.

There's an easier way. And it's one click away.

Your move.
