In this episode of Update:

- Check out the new frames available for those that want to use prescription lenses with Google Glass. However, it's not available for those needing prescription lenses beyond +4 or -4. (I wear contacts with a -6 prescription. So that excludes me and many of my other bespectacled friends.)

- Get the latest report on the NSA, revealing how it collects personal user information from popular smartphone apps. (But one app maker denies it shares data with spy agencies.)

- Learn the new tricks on Twitter's Android app. (iPhone users have to wait.)

- Speculate on the "slim" PlayStation news Sony will share on Thursday.
