The serosanguinous fluid can appear pinkish in color due to the small amount of blood cells that mix with the serous drainage. The consistency of this exudate is watery and thin and typically appears during the healing of wounds.
Bifocals are often prescribed for presbyopia. Bifocals are eyeglasses that have two different prescriptions in one spectacle lens. The top part of the lens corrects for distance vision and the lower portion of the lens is designed to help a person see objects up close.
Unlike a single-focal point lens, BIFOCAL's proprietary lens design creates two focal points for the laser beam -- one focal point is positioned near the bottom of the material and a second is focused near the top surface.
