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.
Again, if you already are wearing corrective eyeglasses, multifocal lenses will most likely be your best option. So letâs start with bifocals. Bifocals come in various styles. At Zenni Optical we offer the most popular bifocal lens style, the flat-top 28 bifocal (FT 28). This means that, unlike some bifocals with a round, near-vision (reading-vision) segment lens, the flat-top bifocal is in the shape of a D turned on its side, with the flat part of the D facing up and the curved portion at the bottom.
