Many jobs, and hobbies certainly, involve manual activity at some point or other, and if you’re handling wood cutting or sawing, screwing or metal cutting and soldering you surely don’t want to hurt yourself. The most sensitive part of your entire body is the one which ironically has to be close to your working surface at all times: your eyes. You naturally approach them to see what’s happening and to guide your movement, and sometimes this can cause terrible accidents. Unlike with your skin or your hands, a splinter of wood or a shard of glass are very dangerous objects to your eyes, and you can easily become blind if something of the sort flew into one of your eyes.
Not being able to see is a terrible handicap and you should try everything to avoid it. It doesn’t even always take something sharp. Sometimes a grain of sand is sufficient to cause a prolonged infection with blindness as a result, and such things can also be very painful aside from the blindness.
But all these accidents can be avoided if you take the necessary precautions before handling any dangerous material. Start by getting a good pair of safety sunglasses. You can work outside in the bright sun whenever you like with these without worrying that some splinter or insect might hurt your eyes, and you can see everything sharply without squinting, so you also prevent other accidents like cutting yourself with a saw by using safety sunglasses. Safety sunglasses aren’t expensive at all because they’re mainly simple tinted plastic, and this enormously helps nevertheless. Even sportsmen routinely wear safety sunglasses for biking, water-skiing or normal skiing and everything similar because they know of the gruesome consequences which some accidents have for your eyes.
