Ah, yeah well, you'd be obsessive about cleaning too if you had the Finest Glasses Ever. Seriously, best ones I've ever had period. I got a rigid titanium frame from TAG Heuer that works very well in holding and keeping the lenses set and rigid. Between the 3 pairs, all the same exact prescription, I can switch sets without any shift in spatial awareness or prescription strength. The set with the higher index Tital glass has a slightly more 'effect', but not overwhelming compared to some other high index lenses I've gotten (plastic). The Titals are a bit heavier, with the titainium oxide mixed into the barium crown flint melt, and the light transmission is a bit lower as well, I use the Punktal for lower light levels, and the Titals for critical precision use. Once you get a set, its like your first B&W frames from a Zeiss lens compared to a bad cheap off brand slow zoom.
