Safety spectacles are glasses/spectacles which are meant to protect the eyes from foreign objects and/or chemical splashes. Safety spectacles can be made up with a prescription to correct the wearers vision or they can be non prescription. Safety spectacles are usually quite large compared to normal everyday spectacles and they fit closely to the wearers head and will have side protection to block any objects or chemicals being splashed into the wearers eyes. People who work in jobs doing wood work or metal work or people working in some types of factories or building sites will be required to wear safety specs to protect their eyes.

There is no problem in using prescription safety glasses as they are designed for a specific job ie yours! However if you are ordering them online you may want to think about what problems you might run into here. For example Do you have a recent prescription you can use? What size of glasses do you need? What safety standards do you need to fulfil for your workplace? It is always best to check with your safety supervisor at work to confirm the safety requirements for your glasses and your workplace. These will vary depending on where you live. Make sure you choose the right safety standards for you job.
