What is the difference of monthly contacts lenses and continuous wear contact lenses?

August 28th, 2010

Marisa M asked:

I am on a trial for monthly day contact lenses at the moment, but the optician has told me to only use them at a max of 12hrs per day because the eyes need oxygen. So if I want to use continuous wear ones, wouldn’t them be bad for your eyes?

How difficult is it to get used to contact lenses?

November 3rd, 2009

Matt asked:

I’ve had glasses for about 3 or 4 years now and recently I’ve been thinking about getting contact lenses. I’ve decided I like the way I look better without glasses. The only thing I’m concerned about is having to touch and put things in my eye. I’m a little worried about not being able to get used to it. So my question is how difficult is it to get used to touching your eyes? Also, does it feel weird having the lens in and if so do you get used to it?

How do colored contact lenses work without tinting your vision?

October 22nd, 2009

MrKnowItAll asked:

I’ve always wondered how colored contact lenses work. Are they completely colored, or is there a clear spot in the center for the pupil?
If they are completely colored, wouldn’t blue contact lenses tint your vision blue, like sunglasses? If there is a clear hole for the pupil, how does the fact the pupil changes size affect things? I would think when the pupil got really small you would see a small circle of the original eye color around it, and when it got big it would tint the edge of your vision.

How much do coloured contact lenses cost a year?

March 15th, 2009

Ken asked:

I want to get coloured contact lenses because I’m kind of sick of wearing glasses. How much do you think coloured contacts will cost me a year? Do you think $800-$1000 a year is enough to put aside?
Is there a difference in pricing for daily/weekly/fortnightly/monthly contacts?

How long can I use my contact lenses?

January 28th, 2009

!!! asked:

I use disposable contact lenses – Bausch & Lomb SofLens (polymacon), 38. I’ve been wearing (these) contacts now for almost 4 months. I wear them almost everyday of the week, for about 12-14 hours a day. I don’t sleep with them on and when they’re not in use, I place them in the solution I was given (which I replace everyday). How long should I use each contact before disposing it? And is it a problem if I use a contact lens and within less than a week there is already a small tear at its edge? This has been happening to me several times within the past 3 weeks or so, so I’ve been throwing out a few lately.
I don’t think I’ve ever worn them for longer than a month…probably 3 weeks at the most.
