You get one free when completing The Second Dream quest. After that you get the normal lenses as a possible reward from the Sortie table, and you can make or purchase more potent versions from the market.

Normal lenses are tradable, and are very cheap due to the better ones being sold in the market for 40p, meaning you can buy a normal lens off of someone for 5-10p.
