From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
Eyewater which makes the Sight Clear, so that no Spectacles are needed.
Take some good brandy of nettles, one drachm of ginger, camphor, fishberry, herb and nasturtium, of each one drachm, of cloves one scruple, of rue toothwort, eyebalm so much as may be held between two fingers (one pinch). Bruise all these articles, and put into the brandy, and distill it in the sun, during the winter season twenty-four days in a warm room. Dip your finger therein and rub the eyelids therewith, mornĀing and evenings, this will keep the eyes clear, and make them strong without the use of spectacles.
The grimoires The Book of Forbidden Knowledge Egyptian Secrets of Albertus Magnus lists this spell.
