Replying to Electric eg2 or 2.5? k+

Yo. I have never liked skiing with goggles cus all goggles I tried have limited my view too much. I have been browsing for some good goggles and electric eg2 seems to be almost perfect and I already found good sale for them too. I don't have the chance to try any goggles on so I just have to buy them at random. My face isn't large but not so small either. I have pretty big nose if that affects anything :D I would rather get eg2 since I just can't ski with small view. Is the difference between 2 and 2.5 big?
+ I will be using them with bell faction helmet :D
