NexOptrics adjustable focus glasses are a single pair of glasses with a dial on each lens that changes the focus strength. You turn the lens to sharpen near work like books and phones, then readjust for distance across the room. They replace a drawer of fixed-strength readers with one pair, and they are light enough to carry. The trade-off is that each lens is set by hand, so two people sharing a pair must reset it, and the focus range is limited compared with prescription lenses.

NexOptrics Adjustable Focus Glasses let you adjust each lens with a quick turn. The same pair can be used for reading books, looking at a phone and seeing across the room.
The glasses are light, comfortable and easy to carry. They can replace multiple pairs of readers.
