Visible Light Transmission refers to the percentage of sunlight that passes through a goggle lens to the eye. A higher percentage indicates that more light is transmitted, making the lens suitable for low-light conditions such as overcast days or skiing in the shadows. Conversely, a lower percentage means less light is transmitted, making the lens ideal for bright, sunny days when glare is intense. For example, a lens with a 60% rating will allow 60% of the available light to reach the wearer’s eyes.
The ability to properly manage light exposure is crucial for visual acuity and eye comfort while skiing or snowboarding. Using an inappropriate lens tint can lead to eye strain, reduced visibility, and even potential hazards such as difficulty discerning variations in the snow surface. The concept of regulating light transmission has evolved alongside advancements in lens technology, with manufacturers developing specialized coatings and tints to optimize vision across a wide spectrum of weather conditions. The selection of the correct transmission percentage is paramount for performance and safety on the slopes.
