PMF Advanced Proof

by Mathew John (2019-12-15)

While some handling tints may affect thePMF Advanced Proof Reviewpatient's eye color slightly, cosmetic or enhancer tints are required to make a purposeful change in someone's iris color. These tints are translucent and blend with the underlying iris color to achieve an enhanced color effect when worSince these lenses are generally created with a light dye uniformly applied on the front surface, dark-color irises do not blend well with the lens color and typically eliminate the blending effect. Light blue and green eyes work best with enhancer tints; and aqua, blue, royal blue, and green are typically the most frequently chosen lens colors.The real color enhancement obtained with these lenses is a combination of the actual lens color, shade, and intensity of the tint; and specific lighting conditions. Hence, an aqua lens from one manufacturer may not look the same as an aqua lens from another, and the color may vary depending on to the lighting conditions.Opaque tints incorporate opaque dyes throughout the lens material and result in a color change that is generally independent of the underlying iris color. They can make brown eyes appear blue and even mask corneal scars. However, opaque tints have been reported to reduce peripheral vision, especially when decentered from the patient's line of sight.
