Like these glasses as have tried a few different items to assist me when doing my cross stitching, which have not quite worked out.
Pros: - glasses with 4 different magnification lenses (have only needed to use the lowest magnification) - light directs to where I am looking - rechargeable, no need for batteries - 2 different brightness (only needed lowest so far) - headband to attach to glasses to stop them slipping (not used yet)
Cons: - glasses are big and do slip but not fallen off that I have needed to use the band yet - after awhile I do find I need a break from them as not use to wearing glasses full time and they feel a little heavy and uncomfortable after long periods.
Overall, the best product I have found for my cross stitching without the need to sit by or clip on a light to see my work which can be restrictive or awkward.
