Should I get and Iphone or Ray Ban Sunglasses?

So for Christmas my mom got me a pair of polarized Ray Ban 3016 49mm Clubmasters but they are too small for my face so I was going to exchange them for the 50mm. The glasses both cost $200.00. Instead of getting the sunglasses should I just return them get my money back and buy an iPhone instead since I have been wanting one for awhile now. What's you're opinion because I'm stuck deciding between the two of them.

Added (1). I already have 2 pairs of Ray Bans but they are pretty old

If I were in your position, I would just get an iPhone!

Well… Ray Bans never go out of style, they will be with you until you break them, and they protect your eyes from UV light. The phone will be in style until the newest one comes out, and will only be with you for, at most, two years.
