3M Securefit400 Safety Glasses - Clear Lens

These glasses offer 99.9% UV protection, which is excellent for reducing UV exposure. However, they feature clear lenses and do not provide tinting for sun glare reduction. For extremely bright conditions, consider models with tinted lenses.

These are designed as standalone safety eyewear and are not intended to be worn over prescription glasses. For combined protection, consider over-prescription safety glasses or safety glasses with integrated prescription lenses.

The lenses feature an anti-scratch coating designed to resist minor abrasions from everyday use. However, they are not indestructible and can be scratched by sharp objects or abrasive materials.

This marking indicates that the eyewear has been tested and approved to comply with European Standards for personal eye protection, specifically EN 166, with '1' signifying optical class and 'F' and 'T' indicating resistance to low-energy impact and high-speed particles, respectively.

Use a soft, damp cloth and mild soap if necessary. Avoid using paper towels, tissues, or chemical solvents, as these can damage the anti-scratch coating and lens material.

The 3M™ SecureFit™ 400 Safety Eyewear is extremely lightweight, weighing only 19 grams.

These glasses are primarily designed for impact and UV protection. While the wraparound design offers some general protection, they are not specifically rated for heavy chemical splash resistance. For such applications, specialized chemical goggles are recommended.

Ensure the glasses fit snugly but allow for some airflow. For persistent fogging, consider using a dedicated anti-fog spray or wipe, or ensure adequate ventilation in your work area.

Adjust the soft nose pads to achieve a more secure and personalized fit. Ensure the temple arms are resting comfortably on your ears.

While the lenses are scratch-resistant, deep scratches can impair vision. Inspect regularly and replace the eyewear if significant scratching affects visibility or structural integrity.

Adjust the nose pads and ensure the temple arms are not applying excessive pressure. The lightweight design and padded touchpoints should minimize discomfort; however, taking short breaks can also help.
