Radiation protective eyewear is a must if your eyes will be exposed to scattered, direct, or reflected laser radiation. There are three basic kinds of laser radiation.
Direct laser radiation happens when there is contact with a beam that directly comes from a laser. It is never good to get hit by a direct beam, whether accidentally or on purpose. Then, there is indirect or reflected laser radiation, which comes from a reflected beam, which typically carries only a fraction of the direct beam’s strength. However, it can still cause serious damage to the eyes.
I remember the days when prescription and over-the-counter drugs used to be quite expensive. As a regular customer (yes, I get to visit the pharmacy quite often), this takes a huge toll on my paycheck (not to mention the entire family budget) whenever someone in my family catches a cold, gets an infection, or any other disease. We experienced a harder time when we get confined in a hospital and have to undergo expensive treatments.
