Fit Over Safety Glasses, called 'Overspecs', are safety eyewear that 'fit over' individual prescription glasses. This type of eyewear is effective and more affordable, but its size can often be bulky and uncomfortable to wear. This can be the case especially for Fit Over Lead Glasses.
Goggles are safety eyewear that completely seals your face, leaving no gaps between the glasses and your skin where fluids or chemicals could splash or drip. They are different to safety glasses which do not seal to the face, leaving some gaps between your skin and the eyewear.
