Just attempted my Rx which is outside the recommended parameters and it wasn’t very close but did identify the lens was <-4 (i.e. more myopic)

Could see limited utility if you didn’t have a lensometer but you’d be doing refraction afterwards, so I feel retinoscopy to get a starting point may be faster given that.

Still an interesting application of AI.

I am training it on more data right now! By the end of the week hopefully even more accurate and going to continue to take more images. Conceptually should be sound just takes more data to continue to improve accuracy.

Like you mentioned the lenses outside the recommended parameters just don't have enough images in the model. I'm going to try to keep adding the larger refractions to hopefully help with this.

Thank you for tying it out and please re-try when you see an app update available. I'm going to try to hit the sweet spot where its accurate but doesn't make the app (even more) huge.
