So lately i've begun working with the arduino, and i've done smaller projects. Now i want to try something a bit more challenging. I've decided to make a pair og smart glasses like the ones google are selling. However i basically just want my glasses to show the time, date, connection, battery life and notifications (Like " is calling"). And this i where i'm kinda stuck. Obviously i need at bluetooth component for the arduino, to be able to connect my phone wirelessly. But how do i send that exact information from my phone to the arduino?
"But how do i send that exact information from my phone to the arduino?"
You might use the forum search function for past similar phone/arduino projects. My feeling from what I've seen is it ain't gonna happen.
The Bluetooth connection to an Arduino is just a serial port. The Arduino only sees what it is sent. It is up to software on the phone to get the information that you want, format the information and send the information. That part is out of the scope of this forum.
The serial input basics tutorial shows how to receive and parse the data coming in from the BT serial port.
What kind of phone?
If an Android based phone.. I would look into using MIT App Inventor.
I have used this a couple times before to create a 'mobile app'... some didnt do much more than work with the native phone settings/contacts/GPS..etc.....
However a few were done using bluetooth to connect/pair with your 'Arduino/BT' device.. and then send data' to the listening Arduino/BT slave..
Basically just a GUI interface of some 'sliders' that represented R, G & B values.. and this data was then sent to the Arduino, and the Arduino parsed this incoming data and acted accordingly to set the RGB led to the specific color..
For myself... I'm more curious as to what you are doing to 'display' this info on the glass? (projected? dedicated display?)... I'm thinking the former if you are going for 'smart glasses'

I am not sure yet, i would first like to get started on how to send the data from my phone to the arduino. Thereafter i will work my way through the other problems.
Well answer the questions presented if you wanting help. 
You have been given one suggestion already...
Whatever phone you have, figure out how you can make a bluetooth app for it.
The rest should be very basic bluetooth 101 stuff.. and Arduino serial data parsing
