| | Molyneux's Problem |
 | | In his account, Cheselden noted that when the boy was first able to see, he did not know the shape of a thing and could not recognize one thing from another, regardless of how different in shape or magnitude they were. |
 | | Whereas Cheselden had only noticed what his patient observed in more or less natural circumstances, later ophthalmologists performed experiments which showed whether their patients were able to see form, size, distance, etc. Some, such as Franz and Nunneley, were especially interested in Molyneux's problem as such, and performed experiments with the prescribed globe and cube. |
