HYDROGEL - ANSWER Soft contacts are manufactured from hydrogel Due to the high water content there are often fluctuations in vision. Benefits of soft contact lenses: - ANSWER •Comfort •Shorter adjustment period •More comfortable in dusty environments •Sports. Excellent for athletics because soft lenses will not fall out of the eye •Good alternative to eyewear for patient with minor corrections characteristics of contact lens materials - ANSWER •Percentage of water content ...

Diffused Illumination - ANSWER -Uses widest slit, longest aperture -Light source positioned at an angle of 40º-50º -Used to view overall areas, to observe the ocular adnexa, cornea, sclera, lids, conjunctiva, lens surface, and CL fitting characteristics Direct Illumination - ANSWER -Most important/useful illumination -Light source positioned at an angle of 40º-50º to oculars -Light beam and oculars are focused in coincidence on area being evaluated -The difference in the illumination...
