Mr. —— optician to the Queen,[12] Her Royal Highness the Duchess of Kent, &c. sole Inventor of Optical Glasses, ground and shaded on the Exact[13] Principle. Mr. —— has been for twenty-five years a manufacturer, who has devoted his study with time to bring this branch to perfection. Mr. —— has been earnestly solicited to pay a short visit for a limited period. He has the honour to announce his arrival from the London, Bristol, and Edinburgh Optical Establishments. Spectacles for far and near distances, for those who have a full eye, ground in a peculiar manner. Sight is often abused by inexperienced persons taking upon themselves the impracticable task of assisting it. The Improved Spectacles, and other glasses, made by Mr. —— on the authority of professional gentlemen, are the very best ever invented; they have gone through a different process, which clarifies and makes them the greatest improvement ever heard of by candle light or dull day. Mr. —— can tell by the physiology and figure of the eye when to give the greatest assistance. His glasses are of a refractive quality; so constructed as to effect the greatest relief; manufactured by machinery of a new construction, and by a peculiar way. Turbid glasses destroy the cornea and iris of the eye, and harbingers all ocular diseases. *** A book will be given for the use of the Improved Spectacles and advice for all diseases. Sight is injured by buying Spectacles of Shops, or other _chance_ places of sale, totally unacquainted with vision. Ladies and Gentlemen whose eyes are weak will, by using these extraordinary Spectacles for two or three hours a week, find their matchless qualities, as they are ground in a peculiar way. Mr. —— will call with a large Assortment. LICENSED HAWKER, NO. —— *** This Circular will be called for. PUFF, No. 2. The sight of the aged assisted by the Improved Spectacles, upon unerring principles. Persons have been going round copying Mr. ——’s Bill, who is the only real original manufacturer of them?[14] it has been the cause of many persons nearly losing their sight, Mr. —— has had fifteen years practice on the eye: there is such a monstrous difference in these improved glasses, that one pair will serve a person his whole life. The sight of the aged assisted, the weak strengthened, and the perfect improved, by Mr. ——’s improved spectacles.
