Safety Glasses 101

Safety glasses are eyewear designed to shield the eyes from hazards such as debris, dust, electrical sparks, chemical splash, and radiation. They are typically used in industrial settings such as construction, mining, manufacturing, military, and automobile repair. The safety goggles have lenses made of polycarbonate, polyurethane, or standard plastic, with a thin strip of silicone across the nose bridge. They are distinct from sunglasses and prescription glasses.

Types of Safety goggles

The main types of safety glasses include side shields, full-face shields, and goggles. The side shields are the most common type of safety goggles. The full-face guard is just like a side shield, but the entire face is covered, thus preventing particles from getting into the face. Full-face shields are commonly used in sanding, grinding, and welding. Goggles are made from hard plastic and have a transparent face shield. They are primarily used in environments with a high possibility of flying debris, such as construction, manufacturing, and automotive repair.

Lens Material

Polycarbonates and Trivex are the most commonly used lens materials. Polycarbonate is also known as shatter resistant and is made of a plastic compound. It has a vast range of optical properties and can be coated with either polycarbonate or polymethyl methacrylate. Trivex is composed of a resin that has increased optical clarity and strength over polycarbonate. It can withstand the impact generally associated with shattering if it is struck by flying debris from an explosion or other sources. Both types of lenses are impact-resistant and lightweight to provide reasonable protection against UV rays.

Fit and Care of Safety Goggles

Safety goggles should fit correctly and should be snug, not tight. They should fit snugly around the head, and the glasses should not touch the face. Safety goggles should be adjusted so that it does not restrict vision as it is worn. It is essential to choose goggles that fit well and provide adequate coverage. Regular cleaning and maintenance of the goggles are also necessary to prevent damage and maintain clarity of vision. You can use anti-fog spray to prevent the lenses of safety goggles from fogging up, which allows workers to continue working safely. Anti-fog sprays are placed on the inside of the lens and spread evenly.

How to Choose Safety Goggles

Choosing safety goggles that provide adequate protection from flying debris and other hazards is necessary. The features essential to selecting the best safety goggles are lens material, lens strength, fit, and type of face shield. The material is necessary because it provides impact resistance, UV protection, and clarity of vision. The safety goggles should be chosen based on the risk involved in that work area.

Importance of Safety Goggles

Safety goggles protect the eyes providing adequate protection from dust, electrical sparks, UV rays, and infrared spectrum radiation. They also protect against hazardous materials such as slurries, chemicals, flammable liquids, dust, etc. Safety goggles are also used for protection from heat and infrared radiation. In welding operations, the goggles protect the eyes from UV rays emitted by arc welding. They also prevent molten metal splatter from entering the eyes. Safety goggles are also used to protect the eyes from debris during sanding, grinding, and sawing operations.

Safety Glasses protect the eyes from flying debris, UV rays, and other hazards. There are three types of safety goggles, side shields, full-face shields, and goggles. Choosing the best safety goggles that provide adequate protection from flying debris and other hazards is essential. While choosing safety goggles, you must consider lens material, lens strength, fit, and type of face shield. Also, choose the one that fits correctly and provides adequate eye coverage.
