I think my eye exam (including the cost of a contact fitting) was under $100 at Wal-Mart Vision Centers (many of them are independently owned, so it's worth looking into even if you are anti-walmart.) And I think just a "regular" eye exam (for glasses only) is under $50.
Once that's done, check out zennioptical.com for really inexpensive glasses. I knows dozens of people that now buy their glasses from them based on my rec and they can't believe what they get for the price. Full prescription glasses start at $8; full progessive bi-focals start at under $50.
Also, Wal-Mart Vision Centers have the cheapest price I've found on contacts and that's without buying multiple boxes at a time (like warehouse clubs and 1800contacts, etc.). Same contacts, better prices.
