Since July I Have Had A Problem With Overbright Appearance

Since July I have had a problem with overbright appearance of everything in my visual field. My retinal specialist originally found some inflammation (iritis) in front part of eye but after some steroid drops that has been gone. Eyes look OK to him. My corneal specialist sees no problems. Internist has tested me for thyroid and auto-immune - negative. MS - no signs. Blood pressure meds - I 've been taken off metoprolol and losarton (Sp?) - no change. Otherwise taking Lipitor and hydrochlorthiazide (visual symptoms not listed for them) . Just about run out of ideas. No other prominent symptoms. Vision not blurry, not double, acuteness not affected (yet!)
