Safety glasses are an essential form of protection for employees of companies where machinery, wind, dust, chemical substances and lasers can put workers vision at risk. Prescription safety glasses provide protection against hazards as well as suiting an individual’s eyesight prescription if they normally require glasses outside of work, eliminating the issues commonly caused by trying to fit goggles on top of their glasses.
Many workers don’t recognise the importance of maintaining their eyesight, particularly when managing a full time job; it can be hard to find the time in your schedule to visit an optician. However, if you work in an environment where you are required to wear safety glasses, you should monitor your eye health more regularly. If you wear regular prescription lenses, they are not a replacement for safety goggles and it isn’t easy to wear them both at the same time either because it stops the goggles sitting correctly on the face, making them less effective. The key difference between these two types of eyewear is the material they are made out of. Some safety glasses need to be made with the same type of material as what is used on wind screens. One of the most common materials safety glasses are made from is Polycarbonate. It offers very high impact resistance, considering its light weight properties. Polycarbonate has a refractive index of 1.59, which tells us how much light moves when moving through a lens. If the refractive index number is high, it has a thin lens. In addition to this, Polycarbonate has a low Abbe value, meaning the material doesn’t distort the image much. Polycarbonate is a preferred alternative to plastic lenses due to its light weight and impact resistance. Polycarbonate lenses are available in the majority of lens styles and offers UVA and UVB protection.
Hard resin, or commonly known as plastic, is almost 50% lighter than glass, however it is significantly less scratch resistant than glass, so requires a resistance coating to prevent this. Hard resin lenses also require a UV protection coating, as it is not a protective material of ultra violet light by itself.
Regular plastic glasses are made of acetate and this material is not strong enough to endure the potential hazards which could occur in an industrial workplace.
Another key difference between prescription lenses and safety ones is the 360 coverage that they provide. Safety prescription glasses have lenses which often reach further round the face than regular day to day prescription glasses. They can sometimes have thicker lenses, which reduce the gap between your skin and the glasses.
