NEW SPECTACLES.
Messrs. Newman and Son, the opticians of Regent Street, have just invented a new form of spectacles. The peculiarity of the construction is, that the frame for each eye is formed in two parts,-or, in other words, the glass is divided in the middle,-one part fixed, the other moveable. The lower or fixed part is of the usual construction ; the upper or move- able part is jointed by a hinge to the top of the fixed part, so as to admit of being placed at any angle with the face, or folded fiat in front of the lower portion. The object of this arrangement is to prevent a strong )
it from acting on the upper part of the eyes whilst reading or writing, G- gas or candle light, or walking in strong sunlight. The result is at- ained by fitting a glass of a neutral tint, or any other colour preferred, in the upper half of the frame. The frame is moved back towards the eyebrows, forming a complete shade. On the other hand, should the light on the book or other object to which the eye is directed be such as it is desirable to diminish, this is at once done by folding down the upper glass over the lower one, producing an uniform shading all over the field of view. Messrs. Newman state that by the new arrangement all kinds of sight will be much benefited, while for India and tropical climates, they think their patent spectacles will be found most effective in guarding the eyes against the glare of the sun.
