Say goodbye to neck stiffness, aches, and strain while reading or watching TV in bed! Prism glasses allow you to comfortably read or watch TV while lying down, preventing neck and eye strain from awkward positions. One Size Fits All: Prism glasses can be worn over prescription glasses, providing clear and crisp viewing for everyone.

Slip them into your bag or take them on the plane or train. Wide Range of Uses: These flat reading glasses help bedridden patients, post-surgery recovery individuals, pregnant women resting in bed, or anyone needing prolonged bed rest to easily enjoy entertainment. They're also perfect for those who spend time reading or watching TV and struggle to find a comfortable, sustainable position.
