Odon,
All my research into Vitamin D and how your body synthesizes it says that glasses do interfere with direct sunlight. I have not research light-boxes.
I researched this because my tests showed my vitamin D levels extremely low in the middle of the summer (July). And my doc recommended vitamin D supplementation.
In addition, the research stated that sunscreens applied prior to going out in the sun or during sun exposure, blocks the body's ability to utilize the sun to produce vitamin D.
The researchers did not recommend going out into the sun without sunscreen they recommended at least 2000 mg of vitamin taken daily.
Some very good information is at Life Extension website.
Their website is www.lef.org if you are interested. Very good site, very good supplements.
Now about contacts I am not sure if that is the same since most contacts are not tinted to decrease the sun's rays. At least I don't think so. I wear glasses constantly because I am very light sensitive, due to adrenal fatigue.
Hope this helps.

At life extensions website they have great information on how vitamin D helps not only with depression but so many other diseases/cancer afflictions. FYI
