Chalkarts,
I believe all editions allowed contact lenses.
SR6, P 274 Optical and Imaging Devices. You buy them so they have 1-3 capacity and the capacity determines how much stuff you can put in them. Goggles and Glasses are the same way. However they are cheaper per level of capacity.
SR6, P275, give you Enhancements, the capacity requirements and cost.
So, you have the pay for the Optical Device AND the Enhancements.
