Modern anti-reflective coated lenses transmit what percentage of light?

95%
99.5%
90%
98%

The correct answer is: 99.5%

Modern anti-reflective coated lenses are designed to enhance light transmission and reduce glare, which improves visual clarity and comfort for the wearer. These coatings work by minimizing reflections from the surface of the lens, allowing more light to pass through. Typically, high-quality anti-reflective coatings can transmit approximately 99.5% of light. This high transmission rate is critical for optimizing visual performance, especially in low-light conditions or situations involving bright light sources. By allowing more light to reach the wearer's eyes, these lenses facilitate better vision and reduce eye strain. Other options do not reflect the current advancements in coating technology. For instance, while a transmission rate of 95% or 98% is respectable, it does not match the superior performance offered by modern coatings, which have been optimized to reach around 99.5%. Therefore, the choice reflecting the highest percentage that aligns with contemporary anti-reflective technology is indeed 99.5%.
