Another phenomenon associated primarily with hard Lenses is "spectacle blur." When a hard lens is placed on the cornea, the surface topography of the eye is altered, so the patient may have visual disturbances with glasses immediately after removing the lens. Spectacle blur, in general, is cleared in about 30 minutes, but use of more oxygen-permeable lenses minimizes the problem. Advantages of hard Lenses include favorable specific gravity (1.18-1.20) and refractive index (1.49-1.50), excellent visual acuity, durability, ability to withstand weak alkalis or weak acids, and no sensitivity reactions when placed on the cornea. Hard lenses are also relatively resistant to the absorption of disinfectants, surfactant cleaners and environment pollutants; they are easy to handle during insertion and removal. Disadvantages of hard lenses include a longer adaptation time, poor oxygen permeation and ocular discomfort.
