Lighter alternative to Vortex Diamondback 10x42

Bought the wife a pair for an Alaskan cruise and excursion and she doesn't like the weight.
Are there any alternatives in the same price range, sub $250, that would be comparable but also lighter.
Maybe the Vortex Solo 10x36 monocular, she does complain about one eye being blurry with binoculars.
