Recent night glares and starbursts from street/head lights. no evidence of cataract or glaucoma. doc said it's due to vitreous degeneration. possible?

Possible: You are tto young for cataracts, and glaucoma doesn't cause glare. The most common cause is an uncorrected refractive error (need for glasses) vitreous opacities can rarely cause this, but they would need to be extensive. This is unlikely at your age.

Unlikely: Incipient cataracts or corneal pathology usually are in the differential diagnosis of glare and star bursts . Vitreous degeneration are not typically the cause of those symptoms. Vitreous degeneration usually just causes floaters.
