Yeah and -7 this is probably something worth spending a bit more money on. I am at -8.5 and starting at -8 the government actually pays back more money and covered the complete cost of my glasses and my lenses up to a certain point as well. (a total cost of about 400 euro).
I really dislike wearing glasses and much prefer my lenses, yet when I come home I often just wear them anyway. Personally, it is something I did never mind spending some more money on as it is something I need to function properly (lenses or glasses)
