If you lay your forehead on the palm of your hand and look down at your forearm, you get a distorted view of the connection between wrist and forearm, as well as a sort of "ghost" forearm silhouette at the margins. What's this called, why does it happen, and are there any paintings or other art that captures these effects?

My vision is changing, which is not unusual, I'm getting older. But I'm having the odd problem when I use cameras (view cameras and medium format as well as 35mm) in getting the best focus (manually). How can I best use cameras, lupes, focussing screens and the like as my vision changes thanks to my advancing years? [more inside]
Assuming you don't drive due to poor vision (so you can't rent a Zipcar) is it feasible to live in the Bay Area and have a decent life, with the ability to get around, go to work, and socialize? With respect to San Francisco and Silicon Valley, what areas would be best, and what parts would be too inconvenient or time-consuming to get by without driving?

My optometrist just spotted a mystery mass in my left eye that's making my vision partially blurry. She's referring me to a specialist in Seattle who can see me in the middle of next month, but I'd really like to get an appointment sooner--and locally. Can anyone recommend a good, competent ophthalmologist with a decent bedside manner in Bellingham, WA?

I found this pinhole glasses sold at the local pharmacy, and feel intrigued by its claim to help me see better and improve my vision overtime (I'm short-sighted). My skeptic alarm rang with warnings (if it's too good to be true, it usually is, etc.), but a quick google-fu turned up nothing substantial to refute such claims. So, does anybody have any experience or anecdotes to share in regards of such product ?

I'm posting for my wife who just got her eyes dilated at 4 p.m. (so she can't look at the computer to type this herself). I tried to Google my question and couldn't come up with any satisfactory answers. The question is why doesn't dilating your eyes and then viewing any form of light harm your eyes? [more inside]

Should I be worried about this? I went to the doctor this morning to get checked out for cold/flu symptoms; I didn't think it was serious -- I just wanted to check that I didn't have H1N1, but the doctor told me that the treatment I'd been getting for prostatitis was "highly unusual for someone in their 20s", and he said I should immediately stop taking the antibiotic I'm on (Septra/Bactrim) because I might be having an allergic reaction to it, or possibly an autoimmune reaction.

I'm considering wearing contact lenses again in lieu of eyeglasses to make working with camera viewfinders easier. I've worn glasses since i was a kid. Got the usual array of problems: Nearsightedness, astigmatism, presbyopia. Currently wear progressive lenses in my glasses. However, I find reading with my progressive lenses is unpleasant, so I usually take them off. I use a separate pair of glasses for computer work. I was fitted with a test pair of soft monovision lenses last week. They're not going to work. Close vision -- within arm's reach -- is unacceptable. I told the clinician I wanted contacts to provide vision correction at least as good as my glasses. I want any contacts I wear to work at distance vision, close vision, reading, driving, computer work, etc. She replied that I wouldn't get that with contacts. Is she right?
I want to color correct my digital photos, but I have a color vision deficiency. Up to now, I've been correcting the levels manually, but relying on the auto-color features in Picasa or Photoshop for colors, but often this doesn't do a good job and the colors look off, even to me. I can manually correct the levels and adjust the colors so they look right to me, but that doesn't guarantee they will look right to others. Is there any way to color correct numerically (for instance, using the eyedropper tool on someone's face to to see if the RGB value of skin falls within a skin-tone range) Otherwise, is there a service that I can send my digital photos to where they can color correct them perfectly and send them back? I'm interested in the digital files, not in getting prints.

Since I last posted I've been feeling much better, but now have very new and strange symptoms. I've been seeing flashes in my vision, felt like I was misreading text or having difficulty expressing myself verbally (words came a bit more slowly than usual), and went to the ER when I saw (and a friend confirmed) my pupils were unevenly dilated. I've also had a recurring, painless rash of tiny red dots that is only ever present on my right hand, and comes and goes rather quickly. All symptoms started two or three weeks ago. I can't see a doctor for a week or two, but when I can, what kind should I see and what should I ask about? [more inside]

My left eye is dead. I just discovered that my left eye doesn't work well. Everything looks blurry at every distance. I can't easily read a book with it, or read a digital clock on the wall. I didn't realize it because my right eye is still OK, and was compensating in focusing things. [more inside]
