At my workplace as a mechanical assembly technician, I have to work with fibre optic cables which involve stripping of fibres and cleaving them.
Every day I am working with glass fibre which can splinter and crack if it does the pieces are often so small that if it gets into my skin I am struggled to see it let alone removing it.
So, for the safety of my eyes is to wear safety goggles when doing a fusion splice. Wearing safety goggles prevent me from any splinters of glass as well as from the chemicals.
Not just at my workplace, I always keep a pair of safety goggles on the kitchen counter at home, so can quickly put them on before chopping onions or frying foods to prevent grease splatters from getting in my eyes. For these reasons I believe safety goggles is a good designed item
