Can one imagine having an eye injury and suddenly losing one's vision? How will one feel if this happens to one or somebody one knows? Although these questions appear very grim, this is a living reality for many people across the globe. Every year, several people suffer from eye injuries and either entirely or partially lose their vision. But the good news is that eye injuries can be prevented by simply wearing a pair of safety glasses. Whether one is at work or gardening at home, a pair of glasses can go a long way in protecting the eyes from harmful chemicals, dust, and hazardous objects.

Meaning
Safety glasses can be made of plastic, glass, or nylon. Still, irrespective of the material, they offer excellent protection to the eyes by preventing dust, debris, and chemicals. They are categorized as Personal Protective Equipment, and their purpose is to protect the workers from harmful materials and hazards. These glasses serve as a barrier or shield to prevent the eyes from getting irritated and injured. In most cases, employers must purchase protective glasses for their employees, primarily when they work with harmful objects and materials.

Types of Glasses
A random pair of glasses can offer a basic level of protection but may not prevent eye injuries. It is because specific glasses are designed for different types of work. For instance, clear glasses can be used for activities that do not require much protection, whereas green glasses are specifically designed for those who work with infra-red radiation. Forensic glasses are worn by scientists and doctors, while protective visors are adorned by sportsmen. Therefore, the appropriate glasses must be carefully chosen for the eye to have maximum protection.

Glasses with Side Shields
Nowadays, most protective glasses come with removable side shields. These are effective ways to prevent debris from entering the sides of the eyes. Harmful chemicals do not only affect the central area of the eyes but can also cause harm to the peripheries. For overall protection of the eyes, side shields are very effective.

When wearing protective eyewear, it is essential to make sure that it fits properly. As one would not want for the glasses to fall off while doing a risky task. . They also shouldn't be too tight and cause irritation, pain, or discomfort. The nosepiece of the glasses must be snug and comfortable without digging into the skin.

To check if the glasses are fitting correctly, one can do a few head rotations and see if they are either too tight or on the verge of falling off.

Maintaining Glasses

Regular inspection and checking of the glasses are a must if one works in a hazardous environment. Safety glasses are necessary to protect one's eyes from chemicals, debris, and other hazardous materials.
