What defines "clear glass"?

"Clear glass" is defined as a type of glass that permits maximum visible light transmittance. This characteristic allows light to pass through with minimal distortion or color alteration, making it ideal for applications where visibility and natural lighting are important, such as in windows and display cases.

The other options refer to specific attributes or purposes of glass that do not align with the definition of clear glass. For example, tinted glass serves aesthetic purposes while altering the visible light transmission and potentially the color of the light that comes through. Glass that blocks UV radiation has a protective function but does not define clear glass, which allows for maximum light transmittance. Lastly, the reference to glass used only for safety purposes pertains to tempered or laminated glass, which has specific safety standards and applications that do not inherently define clear glass.
