The term 'glasses holder' can be broken down into two crossword solutions: 'CASE' (4 letters) and 'EAR' (3 letters). A glasses holder is an accessory used to store eyeglasses when they are not being worn. It typically consists of a hard CASE with a soft interior to protect the lenses from scratches, and an EAR piece that attaches to the frame of the glasses. The CASE provides a convenient way to store glasses when not in use, while the EAR piece helps keep the glasses secure and prevents them from slipping off.
