What is the difference between daily contact lenses and extended wear lenses?
Question: Can we just wash and keep the daily lenses clean like the extended wear lenses?
Answer: Extended wear leanses are designed to be worn continuously. The allow more oxygen to reach the cornea and can be slept in.
Having worn them for 4 years, I can tell you that, while using them is very convenient and comfortable, they can cause problems down the road with dry eye developing later on and corneal scarring.
Contact care is pretty much universal for soft lenses, but I would not recommend extended wear eanses for anyone.
Can you get extended wear overnight coloured lenses?
Question: I wear blue contact lenses all the time and they have power aswell. I liked the idea of extended wear lenses but i like the blue eye colour, do they sell them for extended wear?
Answer: No you can't.
The coloured lenses you get are on older materials – the paint won't stick to the modern high oxygen types that are necessary for extended wear.
Even for daily wear the coloured lenses don't let enough oxygen through if you wear them 6 or 7 days a week. Your eyes would be much healthier and more comfortable with a new modern material – without the colour.
Can you get such a thing as extended wear (overnight), coloured contact lenses?
Question: I wear dark brown coloured lenses all the time (they have a power too), I liked the idea of extended wear lenses but I've never seen them available in colours. Does such a lens exist or do coloured lenses need to made out of a material which makes them unsuitable for extended wear?
Obviously I'm not interested in wearing regular contact lenses overnight, I'd like to get proper ones.
Thanks in advance 
I'm confused now because I've just noticed Acuvue 2 colours say you can wear them for 2 weeks or 6 days continuously? Surely that means overnight?
Answer: i gotta agree with prince again on this one….so far there is no FDA approved colored conatact lens for overnight use. Acuvue has colored acuvue 2 lenses, but these are not approved for extended wear. Acuvue plans to bring a colored version of the acuvue advance to the market, however, they are having difficulty when adding the color to the contact and still achieving a high enough Dk value, the number that is looked at to determine if a lens is "breatheable" enough to sleep in….so bad news, no overnight colors.
30 days extended wear lenses and washing my face?
Question: Hello, I have silicone hydrogel contacts and I read that it's not a good idea to get water in your eyes when wearing them. But how are they extended wear when I have to wash my face and shower every day? Wouldn't it make sense to remove them? I thought I would be able to go a week or so at least without removing them but now I don't know. Is it ok to wash my face/eyes in the morning with contacts in? My guess is – NO but then that defeats the whole purpose of having extended wear lenses…
Answer: Just wash your face and shower in them. I have done this for 40 years with my lenses although I dont' do extended wear. If you can't wash your face adn shower then how can you go out in the rain with contacts in etc. etc. Kind of removes teh whole point of using contacts doesn't it? I'd be careful not to get water in them if possible as it stings, adn if you get shampoo in your eye you'll need to take the contacts out or it'll really hurt, but its not dangerous.
There are a lot of people who seem to think that geting any water anywhere near your eyes with contacts in is a major disaster, but the odd drop doesn't really hurt. My optiican agrees with me on this one by the way. Where you have to be careful is if you swim – I use daily disposables for this now, however I used to swim in hard contacts which we used to keep for 3 years or more. I've never had an infection.
Have just taken out extended wear lenses & put a fresh pair in & my vision is blurred as if i am wearing none?
Question: But when I put my glasses on, my vision is perfect. I have tried two different pairs of lenses but still got terrible vision as if I have nothing in my eyes WHY ????
Answer: Maybe someone packaged "blanks". Call the office of the doctor who prescribed them in the morning and ask if someone in the office can tell if they are prescription lenses. If you bought them from the office, they might replace them for you. If you bought them online, it might be more difficult to get them replaced but I'm sure you can if you persist.
