To the Editor:
—To overcome the disadvantages of presbyopia, many otolaryngologists must change from their ordinary street glasses to their near vision ones, or use a device sold by the instrument makers consisting of a clip to hold a small lens, which clip is attached to the head mirror by three hooks, one in the sight hole and two on the periphery of the head mirror. This is a very handy device, but unfortunately it often slips at most inopportune moments. To overcome this I had a one centimeter lens plus 2 D. spheres made which I fastened by sealing wax, which is permanent but not neat. A few days ago I had the Uhleman Optical Company grind down my presbyopic correction lens to fit the sight hole and it is such a beautiful, neat and permanent job that I want to pass the information on to others like myself.
