Review on O2 Lifecare Protective Shield Reusable by Toki Louton

I use this shield regularly. No problem until winter. Slight inconvenience of fogging the shield when walking out in the cold and then entering the building. I also wear varifocals. The plastic shield causes additional distortions in my field of view. Another bug I've found is that the bottom of the shield touches the collar and lapels of my winter coat and just gets in the way - too many layers of 'things'. However, it is still the best option for people with breathing problems when using traditional masks.
