Road To Sky BOUNDLESS Sunglasses
Made with a high-toughness, lightweight TR frame, this eyewear is resistant to bending, reduces pressure on the head, and offers a comfortable fit. It includes three types of lenses: PC photochromic lenses that automatically adjust color with UV intensity to reduce glare, TAC polarized lenses that effectively filter stray light and glare for clear vision, and yellow night vision lenses that enhance contrast at night while staying bright but not dazzling. The removable nose pads allow for easy cleaning, making it perfect for all-weather cycling.
View the fit guide
1. Measure Key Dimensions (using a ruler or soft measuring tape)
- Overall Frame Width: Measure the distance from temple to temple. The frame width should be close to this measurement (within ±3 mm).
- Lens Width: Determines the field of view and proportions. Lenses that are too wide can look bulky; too narrow can make the face look pinched.
- Bridge Width: Measure the distance across the nose at the point where the nose pads rest. The bridge width should match to keep the glasses stable without slipping.
- Temple Length: Measure the horizontal distance from your eye to your ear. The temples should rest naturally behind the ears without pressing.
2. Check Wearing Comfort
- No pressure on the nose bridge or temples, and the frame should stay in place when you gently shake your head side to side.
- Lenses should not touch your eyelashes and should not be too far from the eyes (generally 12–14 mm eye-to-lens distance).
- Temples and the curve behind the ears should fit closely without pinching.
3. Evaluate Visual Proportion
- The top edge of the frame should align roughly with your eyebrows, and the bottom should not extend far below the cheekbones.
- Frame width should be roughly equal to the widest part of the face (cheekbone to cheekbone).
- Frame shape should complement your face shape: round faces work well with angular frames, square faces suit rounded frames, and long faces benefit from taller lenses.

Three Lens
The BOUNDLESS comes with three lens options: PC photochromic lens, yellow night-vision lens, and TAC polarized lens. Each lens offers UV protection along with anti-scratch and hydrophobic coatings. The cylindrical shape with a flat vertical surface ensures better clarity, reduced distortion, and a full field of vision, while the 5-base lens geometry provides a comfortable space between the face and frame for enhanced ventilation.
Stylish logo eyewear
Add a personalized touch to your ride with ROCKBROS exclusive logo printed on the glossy surface of the glasses. Durable and scratch-resistant, the vibrant logo stays bright and clear, making your eyewear not only protective but also uniquely stylish for every ride.
Removable nose pads and removable temple tips
The BOUNDLESS features removable temple tips with a high-strength, lightweight TR frame, offering excellent flexibility to reduce pressure on the head and ensure comfortable wear. Its detachable nose pads provide a customized fit, keeping your glasses securely in place all day.
UV400
