About Lens category

Lens categories for sports eyewear typically range from Category 0 to Category 4, with each category representing different levels of protection and suitability for various lighting conditions. Here's a breakdown of the categories:

1. Category 0: Clear Lenses

  • Clear lenses are suitable for low-light conditions or indoor sports. They provide maximum visibility without altering color perception, making them ideal for activities such as indoor basketball, racquetball, or gym workouts.

2. Category 1: Lightly Tinted Lenses

  • Lightly tinted lenses are designed for low to moderate light conditions. They offer slight tinting to enhance contrast and reduce eye strain in dimly lit environments. Category 1 lenses are suitable for activities such as hiking, running, or cycling on overcast days.

3. Category 2: Medium Tinted Lenses

  • Medium tinted lenses are suitable for moderate sunlight conditions. They provide moderate glare reduction and enhanced contrast, making them versatile for a wide range of outdoor activities. Category 2 lenses are ideal for sports like golfing, tennis, or skiing in partly cloudy conditions.

4. Category 3: Dark Tinted Lenses

  • Dark tinted lenses offer high levels of sun glare protection and are designed for bright sunlight conditions. They provide excellent UV protection and reduce glare to improve visual comfort and clarity. Category 3 lenses are suitable for activities such as beach volleyball, sailing, or skiing on sunny days.

5. Category 4: Very Dark Tinted Lenses

  • Very dark tinted lenses offer maximum sun glare protection and are intended for extremely bright sunlight conditions, such as high-altitude mountaineering or glacier skiing. Category 4 lenses provide superior UV protection and significantly reduce glare, ensuring optimal vision in intense light conditions.

It's important to choose sports eyewear with lenses that match the specific lighting conditions of your activity to ensure optimal vision, comfort, and eye protection. Always consult with an eyewear specialist or refer to manufacturer guidelines to select the most appropriate lens category for your needs.
