Packing & Delivery

Applicable scenarios
Rock climbing protection: For rock climbing protectors, when providing protection for climbers, they need to keep their heads tilted upwards for a long time to monitor the climbers' movements. Wearing rock climbing prismatic glasses can enable protectors to maintain a level gaze, reducing neck fatigue, while still allowing them to clearly see the climbers' every move and promptly detect and handle potential dangerous situations.
Rock climbing: During the climbing process, climbers need to observe the rock textures above, the position of the footholds, and the direction of the route. Prismatic glasses can help them clearly see the situation above without having to tilt their heads significantly, which is beneficial for better planning of the climbing route, improving climbing efficiency and safety.

Company Profile

Functional Features

Functional Features and Design: The climbing refractive glasses utilize the refractive principle of special lenses to alter the path of light, enabling the wearer to see objects and scenes above at a level close to a horizontal view. For instance, the YY Vertical II plastic difficulty glasses allow climbing protection staff to maintain a horizontal gaze while looking upwards for protection, thereby reducing cervical pressure.
Clear Vision: Utilizing high-quality lens materials such as polycarbonate (PC), these lenses possess excellent optical properties, ensuring clear imaging at all viewing angles and reducing image distortion and blurriness. This allows climbers to clearly observe the climbing route above, the movements of their teammates, and the details of the surrounding environment.
Ultraviolet Protection: It can 100% block UVA, UVB, and harmful blue light within 400nm, effectively protecting the eyes from ultraviolet damage. Even during long outdoor climbing activities, it can reduce the risk of eye diseases.
Impact Resistance: It complies with and even exceeds the ANSI Z87.1 American standard, effectively resisting potential impacts from rocks, branches, etc. during climbing, providing reliable safety protection for the eyes.
Windproof and Dustproof: The combination of the frame and lens is tight, effectively blocking wind, dust, and debris from entering the eyes, maintaining eye comfort and allowing climbers to focus on climbing without being disturbed by the outside world.

FAQ

1. What is the main function of climbing refractive glasses?
Climbing refractive glasses use special lens refraction principles to alter light paths, allowing wearers to see upward scenes (e.g., climbing routes, belayers) while maintaining a near-level gaze. This reduces neck strain during long climbs or belaying, enhancing comfort and safety.
2. Are these glasses suitable for outdoor climbing in sunny conditions?
Yes. Most models feature UV400 protection, blocking 100% of UVA/UVB rays and harmful blue light. Some also include polarized lenses to reduce glare from rock surfaces or water, improving visibility in bright environments.
3. Can people with myopia wear climbing refractive glasses?
Many models support customization for prescription lenses. Some designs include an inner optical frame for myopia correction, while others allow direct customization of the refractive lens to fit individual vision needs.
4. How do the lens materials affect performance?
Polycarbonate (PC): Lightweight, impact-resistant, and ideal for outdoor use (meets ANSI Z87.1 standards for impact protection).
Glass: Offers superior optical clarity but is heavier and more fragile. Choose PC for rugged climbing environments.
5. Will the glasses fog up during intense climbing?
Most frames feature ergonomic designs with ventilation gaps to reduce fogging. For extreme conditions, anti-fog coatings or removable foam gaskets (to block wind and debris while allowing airflow) may be available.
6. How do I choose between semi-rimless and full-rim frames?
Semi-rimless: Lighter weight, suitable for climbers prioritizing comfort and minimal bulk.
Full-rim: Provides better protection against side impacts and debris, ideal for technical or alpine climbing.
7. Can the frame be adjusted for a secure fit?
Many models offer adjustable nose pads, temple arms, or flexible TR90 frames to conform to different face shapes. Some even support 306° frame adjustments for personalized fit during dynamic movements.
8. Are these glasses suitable for belayers?
Yes. Belayers often need to look upward for extended periods, which can cause neck fatigue. Refractive glasses let belayers maintain a neutral head position while monitoring climbers, reducing strain.
