...there are a number of progressive lenses designed specifically for computer work. These have a larger center sweet spot focused at "monitor distance." My optometrist also taught me an additional trick: If you limit the focal range so infinity is not included, progressive lenses work even better for computer work. These are designed specifically for indoor "office" work. You'd wear another, less expensive, single prescription "distance" glasses for driving, etc. (keep them in your glove compartment).

My three favorite "robot stores" are
- Pololu Robotics and Electronics
- SparkFun Electronics
- RobotShop (based in Canada)
I don't work for any of these companies, but in the spirit of full disclosure, I did go to school with one of Pololu's founding partners.

If you want lots of current and future tech professionals to hate you, keep hassling small businesses like SparkFun. Your trademark case against them borders on frivolous. It is a battle that you are unlikely to win in court, and that you will certainly lose in the court of public opinion. Stick with your bread and butter mission: championing the SPARC architecture. Leave popular "Davids" alone, unless the goal is to smear your own brand name.
In grad school I studied and developed methods to make programming accessible to young children. At the time, the general consensus in the field was that before the ages of 11-14, children don't typically have the cognitive ability to write programs, even simple ones. Even though I am a professional programmer now, when I was introduced to BASIC at age 9, I definitely didn't "get it." When I got to 7th grade I did.
Radia Perlman did some groundbreaking work in the 1970's to develop technology in the hope that 6-years-old could learn programming skills. Years later, Ken Kahn developed a game/programming environment called ToonTalk. From my personal experience and research, I don't think you can expect kids younger than 9 to build and program robots, but they can start playing with the physical and conceptual "building blocks."
I see from LEGO's literature that WeDo is aimed at children 7-11 years old. Their approach is very sensible: Keep things very, very simple: One motor, one motion sensor, and one tilt sensor. RoboSoccer can wait until they are older.
