Changes in the colour perception of the human skin due to the natural changes in daylight illumination after ocular plastic and aesthetic surgery

Author: Kazim Hilmi Or
ePoster Number: 218


After ocular aesthetic and plastic surgery patient´s and surgeon´s expectation is the best result with no skin scars seen at daylight.


The colour of the skin and daylight composition during the day are compared with human colour perception.


In the human skin there are reds and beige tones, which may be mixed with some blues. In scar tissues the propotions of different colours change according to the individuall skin colour generally and locally. Human eye / brain can perceive only electromagnetic wavelengths which are in the ingoing light to the eye. Daylight wavelength composition changes over the time at the day, so the human skin colour perception may change with this change, also. Daylight wavelength composition and its intensity changes continuously and uninterruptedly. The proportions change also, when it is sunny , cloudy or shadeo whether it is sunny, in the shadow. When it is sunny, generally there are more reds in the morning and before the sunset. At midday the blue proportion is increased. The proportions in natural illuminations change indoors or outdoors, also. So the perception of normal and operated skin may change due to changes in daylight illumination.


There may be some perception discrepancy at the human skin during natural daylight changes. So the patient and the surgeon should know this fact preoperatively.
