Your vision has changed. It’s gotten worse and now you need thicker glasses to accommodate the new prescription. It happens to the best of us. So don’t be too disheartened. A lens’ thickness is generally determined by a handful of things, some of which may be altered to lighten the load and create a great pair of glass safety glasses.
Why glass safety glasses and not Trivex, plastic or polycarbonate? For one, they generally have a refractive index that runs from 1.5 to 1.9 instead of 1.74. As such, they tend to fit many astigmatism prescriptions without greatly increasing lens size. Plus, they are malleable enough to create bifocals and trifocals without noticeable seams. So oftentimes, glass safety glasses just look better.
Of course fashion isn’t everything, especially when you’re talking about safety glasses. The materials have to be tough enough to safely get a person through his or her work day without scratching, pitting or shattering. Today’s glass safety glasses are capable of doing that. They are extremely scratch resistant and won’t succumb to many of today’s harsh chemicals. On the downside, they may begin to feel a bit heavy after hours of continuous wear and unless treated, may break.
Polycarbonate, plastic and Trivex generally feel lighter do not shatter. However, they are prone to scratch and chemical damage. Accordingly, there are some situations where glass safety glasses would likely outperform them. For example, let’s say that someone is mixing strong chemicals together in the hopes of cleaning an industrial area or commercial products. If splashed on the face, those chemical may quickly eat through the glasses and damage the person’s eyes. So using glass safety glasses in those situations would clearly be the better option.
