Facial Flushing:
Activating C-GMP or rather increasing their levels by phosphodiester-5 inhibition causes decreases calcium influx into the smooth muscle of the vessel and thereby causing relaxation, resulting in vasodilatation and vessel engorgement. This causes increased tumescence of penis or erection. Facial flushing can be attributed to the same reason.

What are the disadvantages of Viagra?
In clinical trials, the most common adverse effects of sildenafil use included headache, flushing, dyspepsia, nasal congestion and impaired vision, including photophobia and blurred vision.Some sildenafil users have complained of seeing everything tinted blue (cyanopsia). Some complained of blurriness and loss of peripheral vision. In July 2005, the U.S. Food and Drug Administration found that sildenafil could lead to vision impairment in rare cases and a number of studies have linked sildenafil use with nonarteritic anterior ischemic optic neuropathy. Rare but serious adverse effects found through postmarketing surveillance include priapism, severe hypotension, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure and sudden hearing loss.As a result of these postmarketing reports, in October 2007, the FDA announced that the labeling for all PDE5 inhibitors, including sildenafil, required a more prominent warning of the potential risk of sudden hearing loss.

Nocturnal animals are likely to have little or no colour vision.Scientists can determine whether or not an animal has colour vision by analysing the "cones" in their eyes. Animals and people have both "rods" and "cones". Rods assist in seeing in the dark; cones assist with colour vision. Animals see colour in varying degrees according to the ratio of rods to cones in their eyes.Colour vision is also determined by the type of cones themselves: there are three types of cones which are responsible for colour vision, and each one has a separate pigment which is sensitive to red, blue or green light.
What light waves that eyes can see?
Humans have three colour receptors in their eyes, and these are active over about half of an octave of frequency. Some insects (e.g. butterflies) have several more colour receptors, and can see over a wider frequency range. Dogs and cats have poor colour vision, for as scavengers, colour has not much evolutionary significance. Birds have very good colour vision, for they must be able to distinguish ripe and unripe fruit. Check the above out in wikipedia under colour vision.
