Correcting lens eye wear came into use a few decades 
after Roger Bacon (1214-1292) did work on optics -- 
especially ray tracing based on a dissected cow eye.  

In addition, 

	A sermon in 1306 given at Santa Maria Novella 
	in Florence by the Dominican Fra Giordano of 
	Pisa sang the praises of the recent invention 
	of eyeglasses.  Fra Giordano said: 

	Not all of the arts have been found, we shall 
	never see an of finding them.  Every day one 
	could discover a new art. ... it is not twenty 
	years since there was discovered the art of 
	making spectacles which help one to see well, 
	an art which is one of the best and most 
	necessary in the world.  And that is such a 
	short time ago that a new art which never 
	before existed was invented ... I myself saw 
	the man who discovered and practiced it and I 
	talked with him [4].
