A:AnswerI have only seen them come in black, however they have different lenses you can buy and change out. You can also take to the eye doctor and have them insert prescription lenses.
A:AnswerThey connect through Bluetooth and can work with or without Wi-Fi. I have the same pair as you do so I don’t line the difference between 1st & 2nd generation
A:AnswerA nice hard carrying case is included. You should be able to take the glasses to Lense Crafters for prescription lenses. I also got an extra pair of lenses through Best Buy as a promo around Fathers Day last year.
