In the usual combinations of helmets and eye protection products, the position of the glasses is always directly dependent on the position of the helmet shell. In the event of a sudden movement of the helmet, this automatically leads to misalignment of the visor and the associated risk to eyesight. IES stands for Integrated Eyewear System, and the name says it all: a glasses holder allows the uvex pheos safety glasses to be stowed away in the uvex pheos helmet via a slider or pulled down onto the nose. The slider is equipped with a joint part so that movements of the helmet do not affect the glasses.
