i wear contacts everyday the reason they feel great ans somethime they feel gross is because sometime ur eyes have alot of water in them to the contacts feels niec but sometimes ur eye doesn't want a contacts in it and ur eye might be dry so you feel discomfort in ur eye. That what my optomitist said.

Try AMO Complete solution. You should check with your eye dr. before resuming contact lens wear though.

Hard and soft contact lenses are prescribed and fit differently.  (You can't just take your hard lens prescription and order soft lenses from it.)  Astigmatism in general is correctable with either type of lens.  Only your eye care provider can tell you if soft lenses will work for you, so make an appointment to see your optometrist or ophthalmologist.  You should also be sure to have a yearly complete eye exam to make sure that there aren't any problems with your contact lenses and to check the overall health of your eyes.

They are all different materials (plastic polymers)that contacts are made out of.  Etafilcon A is what Acuvue and Acuvue 2 are made of.  Phemfilcon A is FreshLook and ocufilcon D is 55.  Each material is made by different companies and does essentially the same thing.

You hit the nail on the head.  I have severe astigmatism in one eye and slight astigmatism in the other.  If I don't wear the proper contact lenses in each eye my vision is extremely blurry and eventually I will get a headache.

Glasses and contacts operate on the same basic principles, but contacts have to accomplish the same thing in a much smaller space (for obvious reasons).  Contacts are often made out of more bendable materials, for comfort.  Since they are closer to the eye than glasses, they are also more curved.  I suspect that the materials used in contacts may have a higher index of refraction than glass, since they're not as thick, but I don't know if that's true or not - just conjecture on my part.

Nothing at all should happen as long as you took the contacts out fairly quickly and washed them.\n\nIf not, and they aren't one day disposables, you may have to get them checked by an optician as the chemicals in the medication may affect the lens

Maybe if you mess up your eye with toxic waste, antoher than that I'm not sure. But I found this one cool pic when I seen the thing about the contacts. It's true they are real. But as I was looking they are like $200 for a pair. Which if you really love 'em that much is pennies.

How long have you been wearing your current lenses?  Have you been disinfecting them properly (as your doctor instructed you)?  Are you using a different brand of contact lens solution?  Sometimes you can develop a sensitivity to a solution after you've used it for an extended period of time.  Consult an eye doctor (optometrist or ophthalmologist) you trust for more specific answers to your questions.

You also may want to ask the optometrist - I have astigmatism and when I went in for new contacts 6 months after my last eye exam, I found out my eye had changed shape quite a bit, changing my prescription for the toric lense (my weights wouldn't hold in the right place).  The blurriness has to be the weight swinging wrongly.  \n\nYou know, it could also be that the company screwed up on your order - maybe give them a call.

There are many different types of lenses. Here's a site with good information.

i think that it might be okay if you keep it in the solution for a month (you might want to replace the solution every 5-7 days.. but check with your optometrist first) but DON'T swim with them.. when soft contact lenses get completely wet, they stick to your eyeball like no other.. and it becomes really difficult to remove them.. i know.. from experience :/

you can buy colored contacts with no correctiveness, but they're expensive. most any place that sells contacts has them

Both have the same number

I've seen two people with pale purple irises, before the time of colored contacts. So it must be possible.

Yes.  Contact lenses (the soft ones), are made of a special hydrogel.  This allows the contact lens to sit on your eye daily without irritating it (I know they irritate a bit but trust me.. it could be much worse!).  This places them in the classification of biomaterials.  \n\nBiomaterials are materials that come into direct contact with the body but are not 'of the body' so to speak.  Whenever something that is alien to the body (and this includes non native organ donors), an immune system response will ocur.  This will lead to inflammation depending upon the extent of the immune response.\n\nThe extent of this inflammation depends upon how biocompatable we can make the material.  Hydrogels are what we call very hydrophilic.  That is that they bind very well with water (and are indeed mostly water which is very biocompatable).  Thats why they slip and slide and are a bugger to get in and out of your eye.  This enables them to sit on your eye with minimal immune response.\n\nHowever, over the course of the day bacteria and dirt binds with the lenses.  Soaking them over night in saline and treatment disinfects them.  If you don't disinfect them, bacteria and dirt in general triggers a bad immune response of inflamation.. hence the red eye syndrome everyone hates.  \n\nAlso, because they are hydrogel, over the course of the day they can dry out.  Blinking unfortunately is not sufficient to keep them hydrated.  As they dry out they shirnk a bit and become quite hard like a plastic almost.  You can see this if you leave an old lens to dry out on the side for a bit.  This further becomes an irritation as now, rather than having a very soft lens on your eye, you've got a lump of hard plastic.\n\nFinally, with them also being very hydrophilic, as they dry out they will try to absorb water into their matrix from your eye.  This creates (in short detail) a bond between your eye and the lens making them also difficult and uncomfortable to remove.\n\nSo to summarise, don't leave em in.  It can be uncomfortable and potentially hazzardous for infection.  Also keep em clean or use new ones daily!\n\nHope this helps.
