In some states, opticians may be licensed to fit contact lenses. Opticians often work closely within the same practice as an optometrist or ophthalmologist, or an optician may have an independent practice. An ophthalmologist is a medical doctor who is specialized in eye and vision care.
Kant s links. http://comp.uark.edu/~rlee/semiau96/kantlink.html. For Kant the basis for a Theory of the Good lies in the intention or the will. Those acts are morally praiseworthy that are done out of a sense of duty rather than for the consequences that are expected, particularly the consequences to self. The only thing GOOD about the act is the WILL, the GOOD WILL.
Immanuel Kant. Enlightenment is man's emergence from his self-imposed nonage. Nonage is the inability to use one's own understanding without another's guidance. This nonage is self-imposed if its cause lies not in lack of understanding but in indecision and lack of courage to use one's own mind without another's guidance.
