Nice collector of optical eye related equipment.
The trial lens set is circa 1900 and different in that it is in a doctor bag style carrying case instead of an awkward large rectangular case. Has 3 trays of lenses and adjustable glasses frame for determining a frame.
The contact lens set is complete and circa 1935, one of the first sets!The rubber suction bulb for removing and inserting the lens  is hardened and no longer usable.
The opthomaloscope has different lenses and was used to look in the eye and determine what grade and type of correction was necessary for corrective lenses.
The schematic eye has a set of retinas and was used for reference and teaching to diagnose various eye conditions. Trial lenses could be fitted on the front so the doctor could determine the necessary corrections.
Lastly the simple eye scale was a crude eye tester. By sliding the target until it was in focus and "count the dots" it gave a crude reading for corrective lenses for either near or far sighted. Many times these were sold as a do it yourself test to determine the strength of glasses one could order at home.
