I get the impulse to stretch the wear of contacts (I would often change after 3, 3.5 weeks myself, mostly because I forget exactly when I opened the last pair) but EIGHT weeks is way too long, and potentially dangerous to your eyes. When I was a teenager I was terrible at following contact guidelines and ended up with microblisters on my cornea. Older contacts also are more prone to protein and bacterial building up on the lens as well. If you seriously damage your eyes, you could be setting yourself up for pretty expensive issues in the future. That's being penny wise but pound foolish.
I've switched to daily disposables, and bought a pair of glasses that I like and look good in ($95 at Warby Parker, paid for with HSA money). Every day that I won't be outside in the sun (the main reason I dislike wearing glasses is the sunglasses problem), I wear glasses instead of contacts. That's probably half the days, so boom. Spending half as much money on contacts, giving my eyes a healthy break, and not risking eye damage.
