Sunglasses typically boast tinted lenses, which serve the primary function of mitigating bright light and minimizing UV exposure. Alternatively, Power Glasses serve a primarily corrective purpose, employing lenses that are specially designed to address and compensate for vision impairments like myopia or hypermetropia.

Sunglasses might be utilized in various light conditions but predominantly find their use under bright or glaring light scenarios. Power Glasses, however, find consistent usage across varied environments, serving as a necessary tool for individuals to experience clear vision, irrespective of light conditions.

Sunglasses often come in various styles, tints, and forms, offering aesthetic choices alongside their protective functionality. Power Glasses too can be stylistically diverse but are ultimately shaped by the need to cater to the wearer's specific vision correction requirements, such as bifocal or multifocal lenses.

Sunglasses, while providing a necessary shield against light, do not correct vision. Power Glasses, on the other hand, do not inherently offer protection against bright light or UV rays unless they are specifically treated or tinted to do so.
