How to Recognize Safety Glasses

Whether you are working in the shop, yard or even the workplace, safety glasses are an important way to protect your eyes and face from dangerous debris or noxious chemicals. Not just any pair of glasses will provide proper protection, so it is critical to be able to recognize proper safety glasses. Although they may at first look like a regular pair of glasses, safety glasses contain special features such as shatter-proof lenses and impact-resistant frames.

  Look for impact-resistant lenses on the glasses. These types of lenses are also known as Plano lenses. This feature is designed to repel the flying dirt or debris created by certain jobs. Plano lenses can be flat or curved, depending on the style or function, and may be clear or tinted. The lenses may also be removable, and, in some instances, are available as prescription lenses.

  Safety glass lenses are generally made from one of three materials, and each provides a different level of protection. Plastic lenses are lightweight, less likely to fog and protect against welding splatter, but are susceptible to scratching that can decrease range of vision. Glass lenses are more scratch resistant and may be used when working with dangerous chemicals. Although they can be purchased as prescription lenses, glass lenses may be heavier and more uncomfortable than plastic ones. Polycarbonate lenses share some of the same features as plastic lens but are stronger in composition than both plastic and glass. Most importantly, they resist impact better than the other two materials.

  Choose frames that contain the appopriate temples, or the way the frame fits over the ears. Headband temples can be worn around the head. They adjust easily for a snug fit and are ideal for jobs that require a lot of movement. Cable temples fit around the ear, making them extra secure, and some styles are adjustable. Spatula temples resemble regular glasses because they fit over the ear and are therefore less secure than cable and headband temples. Despite their design, one of the most vital aspects of safety glass frames is that they conform to the user's face correctly and comfortably to ensure protection.

  Consider side shields, an additional component to some safety glasses. This feature is useful for jobs that require side protection from debris and impact. Shields may be solid or have built-in ventilation for sweaty jobs. Some side shields can be removed from the frame while others are permanent. The shields are available in both tinted and clear varieties to suit an array of tasks.
