Final answer:
Lee Optical v. Williamson: The Supreme Court upheld a state law requiring an optician's prescription for eyeglasses as a valid exercise of state police power.
Step-by-step explanation:
In Lee Optical v. Williamson (1955), the Supreme Court addressed Oklahoma's law requiring an optician's prescription for eyeglasses. The Court affirmed the state's right to regulate businesses and protect public health, stating that while the law might inconvenience some, it was a legitimate exercise of state police power. The decision emphasized that states have the authority to enact regulations aimed at protecting public welfare, even if such regulations create economic burdens or inconveniences for certain industries or individuals.
The ruling reaffirmed the principle of state sovereignty in implementing regulations deemed necessary for public well-being. By upholding Oklahoma's law, the Court set a precedent for states to enact regulations concerning health and safety, even if they might impact the economic interests of particular industries or businesses.
