The Eye is one of the most delicate organs oi nature. From the fear of appearing ancient, many persons refrain from artificial aid when really needful. It is absurd, and only aggra- vates the defect and causes disease of the optic nerve, which may become chronic, and finally result in premature blindness. Non- professionals should never be allowed to tamper with the eyes, because the sight changes at different stages of life, arising from several constitutional causes, known solely to the OCULIST, to whom application should be made immediately it occurs, as delay often results in serious consequences. The opto- metric treatment not only remedies defective vision, but it has frequently restored the eyes to their proper functions from a state of com- parative blindness. It is the only accurate method known to modern science for detecting the several affections of the eyesight, which comprise Myopia, Presbyopia, Diplopia, Hemeralopia, and Ciiromatopseitdopsis. The press, and eminent medical men, pro- nounce Mr Solomon's OPTOMETRIC treat- ment to be a marvel of the age, and recommend its adoption by those whose eyes have deviated from their usual functions ; it has completely revolutionised the dreadful system of the sight being so fearfully injured in the selection of glasses from incompetents, and also clearly proves that persons can't possibly gauge their own precise focus of sight. The various eye diseases, such as Amatteosis, Cataract,Ophtiialmia, Staphyloma Specs, or Films on the eye, and any other blemishes can only be detected by a combination of Mr Solomon's Optometric and Opthalmoscopic observations. There exists an erroneous idea that when once glasses are adopted they can't be discontinued. Such is only a fact when unprincipled vendors of spurious spectacles are resorted to and their countei-feits worn too long. Donders, who is acknowledged to be the highest authority on the science of optics, says in his treatise on the refraction of the eye : — "So far from short-sightedness im- proving in advanced life, as is popularly be- lieved, it is too frequently a progressive affection, and every "progressive Myopia is threatening with respect to the future, inas- much that if not checked in due season by the aid of Suitable Glasses, the vision will be irrevocably lost. Spectacles or eye-glasses, if injudiciously selected, usually aggravate the evil they are intended to remedy.
