Are there preservatives in saline solution safe?

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.

Is drinking tea without tea bags better for you?

You've been a hero(ine) of mine for quite some time. I hope YOU can answer this question (it seems no one else can).

I've been reaping the benefits of green tea for about a year now, and I feel great! Just recently I began opening the tea bags after brewing, and putting the tea leaves in with the actual brew and drinking the leaves as well. Does this add more health benefits to green tea? I would think so! So far, no one has been able to answer this question directly. Please let me know if you know!

Stay Awesome Alice! May your boards hum forever!

Can my diet or anything else help this problem?

Which type of contact lenses are better?

I read that disposable contact lenses are actually worse for your eyes than the normal one-year ones because they allow less oxygen to go to your eyes, and the only advantage is that there are less cleansing problems. Also, it is claimed that inadequate oxygen to your eyes (possibly caused by prolonged wearing of contact lenses) leads to a condition when extra blood vessels sprout around the iris, which leads to sight problems at old age. Is that true?

I am very concerned because I normally wear (one-year) contact lenses from 8am to 8pm, and maybe to 12am during reading periods. I don't feel very comfortable with glasses because they give distorted visions and fatigue. I thought switching to disposable contact lenses would do my eyes good. My current lenses contain 38 percent water. Is this good enough?
