THOs. HARRIS & SON'S
CRYSTAL SPECTACLES.
Improved Achromatic Telescopes.
THE BEST FOR PRESERVING THE SIGHT.
By using Harris and Son's Spectacles, the many painful sensations in the eyes so frequently complained of by ladies when at needle-work, music, &c., are removed; they are very beneficial by candlelight, and enable the wearer to continue reading a much longer time without fatigue, or the risk of injuring the sight.
T. H. and Son have especial regard in adapting the proper shape to fit each person's face. Badly formed spectacles subject the wearer to many annoyances, such as continually shifting their position from the eyes, the frame intersecting the sight, causing too much pressure on the temples, disarranging the hair, marking the nose, &c.; these inconveniences may be avoided by the use of T. H. and Son's spectacles, which from their light (nearly invisible) appearance, do not at all disfigure the countenance; and being composed of pure crystal, are the most efficient for preserving the sight.
