What do cataracts look like?

Cataract appearance. With a slit lamp (the microscope at the ophthalmologist's) cataract is very easy to see as a clouding of the natural lens. From the patient's perspective it is a very gradually progressing film over the vision and glare from lights. Patients sometimes describe it as "looking through cheeseclothe." the term cataract means waterfall, presumably as if you're looking through a waterfall.
Wide variety. When we look through the microscope to examine a patient for cataracts, we can see several types of cataracts, all with a unique appearance. For instance, a psc cataract looks like sugar or salt crystals! some cataracts alter the clarity of the lens of the eye, and change it to a greenish-yellow color. Another type can look like bubbles in soda pop.
Cataracts. Cataract cause: Cataract occur from change in lens proteins which cause whitening/clouding/opacity of lens (cortical, nuclear, PSC types can be seen under microscope): can be due to: infection/ inflammation from birth/congential (ie, rubella), old age (senile)/genetics, steroid use, trauma (causes acute change), poor diet; smoking, Diabetes increases risk. eyedoc2020@blogspot.com more info.
Not visible in most. A cataract is a clouding of the natural intra-ocular lens. The lens is behind the iris and pupil and is not normally visible to the naked eyes. Only the most advanced cataracts, the so called, white cataracts, are readily seen as a white spot in the middle of the eye (or through the pupil).

Different types. Lens that is no longer clear, commonly there are nuclear sclerotic changes, which can cause browning of the lens, cortical, posterior subcapsular opacities that build up make the lens not clear. It's possible to have a congenital cataract at an early age or have secondary cataracts due to things like trauma. It's too hard to see the cataract without a dilated slit lamp photo. Read more...
Normal to white,rare. When the natural lens is cloudy it is termed cataract. Most can not be seen just by looking at someone without the use of eye equipment. If it is very cloudy, white, or very dark brown it may be seen by the naked eye. Because only advanced white cataracts could actually be seen, in ancient times doctors thought it looked like a waterfall. 20's unlikely. Diabetes, medicines, trauma can cause them. Read more...
