My eyes feel dry and swollen after hours of staring at the computer monitor. Is there any long range harm caused by spending both work and play time in front of the computer? I work out, and eat a healthy, low-fat diet. I don't have any other vices except perhaps a higher than normal caffeine intake.

My question is regarding eye exercises. I am short sighted and wear my glasses constantly. Recently I came across some eye exercises which claim that they can help you restore your vision. Their reasons seem convincing. But if this were true, why do the majority of people with poor vision still wear glasses. I just want to know if it's possible to restore your vision by doing these exercises? If not, is there any other way to restore vision without undergoing surgery? Finally, is there any way to ensure that my eye sight does not get any worse?

During sex, my husband likes to squeeze and suck my nipples. I enjoy this, but am worried that this type of pressure on the nipples may cause problems later on: we are planning on having a baby in a few years, and I want to breastfeed. Might the pressure of squeezing and sucking hurt my mammary glands and ducts, making it difficult or impossible for me to breastfeed?

As an avid contact wearer, I use saline solution to rinse my contacts daily before each use. Recently, a friend told me that many commercial saline solutions contain preservatives, which could affect the overall health of my eye. Is this something I should be concerned about? The saline I use has always felt comfortable so I never thought it could pose a problem.

I was hoping you could answer a question for me about birth control pills. There is a history of breast cancer in my family (my mother). Is it true that because of this, it is unsafe for me to use birth control pills? A few friends have recently had condoms break during sex, and I am looking for a type of "backup" contraception system.

Is there a reason behind spontaneous nipple hard-ons? Lately one of my nipples just stays that way for the majority of the day. It's irritating! Is there a reason behind it?

Dear Alice,

Is it dangerous to sleep in your soft disposable contact lenses for one night if you can't get them out?

My eyes are light-brown, and when I've been crying or when it's bright outside they look greenish. I want my eyes to be that greenish all the time. I heard that putting honey in your eyes will lighten them. Are there any side effects? Is it bad for my eyes?

1) I am a male with inverted nipples.

I was wondering if there is any way without surgery to make them come out. They do sometimes come out when it's cold, but go straight back in. I am not overweight, but I do no sports. Would physical activities help???

2) I have inverted nipples. Is there anything that I can do to make them come out? I think that they are unattractive inverted. I have tried massaging them daily as doctors and magazines have suggested, but they do not stay out. They have only come out a couple of times when my boyfriend has sucked on them. Is there something wrong with them? One doctor said that I might have to get a minor surgical procedure.
