It drives me nuts that contact lenses are now so thin and flexible that, whilst super-comfortable to wear, they can easily become inverted in the packaging.
When this occurs, I can’t easily detect it and so have to extract and reinsert (with all the handwashing and eyelid-pulling pallaver that that entails).
Today’s invention is a C-shaped plastic bracket onto the lower-surface of which an opened, transparent lens package is placed. A small lamp on the lower surface shines upwards through lens, liquid and case to form an image inside the upper arm of the C.
The resulting image is different in size, depending on the orientation of the lens.
