Q:what is pigment dispersion syndrome?

Pigment dispersion syndrome (PDS) is an affliction of the eye that, if left untreated, can lead a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. This is not what causes problems; however, if the pigment flakes clog the trabecular meshwork, preventing the liquids in the eye from draining, pressure can build up inside the eye. This pressure can cause permanent damage to the optic nerve. This condition is rare, but occurs most often in Caucasians, particularly men, and the age of onset is relatively low: mid 20s to 40s. Most sufferers are nearsighted. There is no cure as of yet, but PDS can be managed with eye drops or treated with simple surgeries. If caught early and treated, chances of glaucoma are greatly reduced. Sufferers are often advised not to engage in high-impact sports such as long-distance running or martial arts, as strong impacts can cause more pigment cells to slough off

Q:Can you take any powder, grind it finely, and mix linseed oil into it to make oil paints to make paint? Or do paint pigments have to have special characteristics? Thanks!!

Pigments are specific minerals found in rocks. Then they are ground down and mixed with the binders for oil, acrylic, and watercolor paints. You can take art classes that teach you how to make your own paints. I have a cousin who hikes to find her own pigments and makes all the colors she paint with. If you'd like something less labor-intensive, you can buy the pigments you want from lots of art stores these days. They can be added to pre-existing colors to enhance them, or you can start from scratch to formulate your own colors. The bottles i've seen are around 8 ounces, and cost about $50. You will likely find books in the library and articles online that will help you learn to make your own pigments.

Q:I am about to purchase a bunch of MAC pigments and I have noticed that they all look glittery, is this just the kind that i am looking at? I know they are versatile, so that is why i want to buy them. And it seems as though they will last longert than eyeshadow...

Of course they can ! I love mac pigments. Yes, fallout is involved..but what i do is i use my mixing medium with them so that they go on wet and no fallout. If you don't have mixing medium you can mix them with eyedrops. What i do is i put a drop in the lid and pick up some pigment and mix it till i get the perfect consistancy. You can also learn how to press them, so that they can become pressed eyeshadows instead of loose. But if you just want to use them loose, make sure you get a good flat shader brush...make sure you pat the pigment on your lids insted of in a swiping motion, this also prevents less fall out. Get some loose transparent powder as well set that under your eyes, and swipe it off when done..this makes the fallout swipe away without smearing on your face.. Hope that helps ! If you want you can do all of this, but you don't have to...just random tips to prevent that annoying fallout

Q:I have been looking over the internet and have yet to find the details I need. Such as the function and development of Pigments.

A pigment is essentially a substance that subtracts light to produce a variety of colors. In organisms, pigments are the colored matter (the substance in your cells that give your skin, tongue, hair, etc. their colors). In nonliving things such as painting, a pigment is the dry powder that is mixed with a fluid, creating a colored liquid which is then used to paint. As to how pigments work -- the pigment absorbs all light except the color you see. That color of light is reflected to your eyes. All kinds of substances can be pigments. I hope that was clear and answered your question!
