Contrast sensitivity: Being able to see someone's features when a light is behind them requires contrast sensitivity as well as your visual system being able to handle glare. I recommend test for glare and special testing for contrast sensitivity at your ophthalmologist's office. If he or she doesn't have the necessary equipment, obtain a referral to someplace that does. Also, make sure there is no residual astigmatis.

See Your Eye Doctor: This sounds like an issue of loss of contrast sensitivity, which can be associated with multifocal lenses. However, it is uncommon for that to produce total blackout of a portion of the vision. See your ophthalmologist for a visual field test to ensure there is no blind spot in your vision which might point to a different problem.
