A:AnswerDefinitely, I used it every day and haven't seen any negative differences with having the glass shield. Plus it's helping protect my actual screen from the pen.
A:AnswerThe protector is affixed onto your screen and does not need to be removed for each use. It is an extra optional film to protect your screen. The protector itself is clear so i don't see it being bad on the eyes. I only experience temporary vision issue after prolonged viewing of any lcd type screens. My age might have a part in that.
A:AnswerFor me, I do not really feel any weight difference. At least not a big enough difference that would steer me aware from the value of protection they provide together.
