Protective Glasses MCR Safety Karn-OTG with clear UV lenses and grey-green frame

The MCR Safety Karn-OTG protective glasses provide practical eye protection designed to be worn comfortably over most prescription eyewear. These safety glasses feature clear UV-filtering lenses that reduce exposure to harmful ultraviolet light while maintaining undistorted, high-visibility vision. The grey-green frame offers a neutral appearance suitable for industrial, workshop, and general safety environments where unobstructed sight and UV protection are required.

Advantages

These over-the-glasses safety glasses combine compatibility with prescription eyewear and integrated UV protection in a single, lightweight unit. The clear lenses preserve accurate colour perception and detail during tasks, while the frame contours are shaped to fit over spectacles without creating excessive pressure points. Materials are selected for durability and everyday use in industrial and workshop settings.

Suitable for

• Wearing over prescription glasses in manufacturing and assembly work
• General workshop tasks such as machining, carpentry, and maintenance
• Laboratory and inspection work requiring clear vision and UV filtering
• Light industrial and facility maintenance where impact risk is low to moderate

When it may not be suitable

These glasses are intended for protection against UV exposure and general safety use; they are not certified for high-impact ballistic protection or for environments requiring sealed chemical splash protection. For tasks with very high impact risk, molten metal splash, or hazardous airborne particles that require a sealed respirator-fit face shield, consider specialized protective equipment instead.

Key specifications

• Lens type: clear with UV filtering
• Frame style: over-the-glasses (OTG), grey-green
• Compatibility: designed to fit over most prescription eyewear
• Intended use: general eye protection in industrial, workshop, and laboratory settings
• Fit: lightweight construction for extended wear

How to use

Place the Karn-OTG glasses over your prescription eyewear so the frame rests comfortably on the bridge of the nose and the temples sit securely over the ears. Adjust the position to ensure lenses are centered in front of the eyes and provide an unobstructed field of view. Clean lenses with a soft cloth and manufacturer-recommended cleaner to maintain clarity. Inspect the frame and lenses regularly for cracks or scratches and replace the glasses if any damage compromises fit or visibility.

What to consider before purchase

• Verify that the OTG frame will fit over your specific prescription glasses without excessive pressure
• Confirm that clear UV-filtering lenses meet the UV protection needs of your tasks
• Assess whether additional protection (e.g., full-seal goggles or face shield) is required for your work environment

Usage recommendations

For routine maintenance and light industrial tasks, wear the glasses whenever there is a risk of particulate exposure or UV sources are present. Store the glasses in a protective case when not in use and replace them if lenses become scratched or frames distorted to maintain effective protection and clear vision.
