I've been using these contact lenses for quite a while now. I started off buying them at my opticians for about £150 for 6 months supply, but now I get them through Asda for £50 for 6 months. What a saving!
Mostly, I don't have any trouble with these contact lenses. Sometimes they move around in my eyes - this is usually if I'm tired, but they move back to the right place pretty easily. I've never had issues with them splitting or anything unpleasant like that! By the evening they can dry out a bit, but I think this is down to my eyes and the atmosphere around them, not the lenses themselves. I can often keep them in from 8am until 1am if needed.
These work with normal contact lens solution - none of that scary fizzy stuff that has to be used for just the right amount of time or your eyes sting. This is very handy as if you forget to add the solution at bedtime and they are all shrivelled up in the morning, steep them for half an hour or so and they are back to normal again - although it's a good idea to take some solution to work with you on days like that just incase they dry out. Probably not very good for the lenses... They probably aren't very good for people with dry eyes either.
I do find that towards the end of the month they aren't as great. I try to eek as much use out of them as possible. I have no idea what date I'm meant to change them - I'm not very good at marking these things down, so although they move around more/ dry out quicker towards the end of the month, which can be quite unpleasant, at least you know when it's time to open a new pair.
They come in easy to open packs, which are stored in easy to open boxes. Labelled with your prescription so you know which is which.
I wouldn't consider changing lenses. I've tried others in the past which haven't been as good, and my optician recommends these for me anyway. I think they are perfectly acceptable contact lenses - and I prefer wearing these to wearing glasses anytime. I love wearing contact lenses. I can't peel onions if I wear glasses, glasses hurt behind the ears, get in the way, can fall off, steam up when you drink tea or eat pasta and are generally very awkward. You can forget about contact lenses (until you need to take them out) and you don't have to worry that they don't match your top! I think I probably just need to get more sleep to make them work better.
These were the first contact lenses I ever tried and although I changed a few times after, these are some of the best ones I have used.
With any lenses, you have to ensure they fit the shape of your eye and these I found were comfortable with no squeeze or pressure on my eyes.
I found that it is pretty easy to check the lenses are the right way up is quite easy especially if you hold them up to natural light. If unsure flip them the other way and it should be very obvious. If you do get them the wrong way you will feel it.
I found that provided I kept hydrated and wore sunglasses as much as possible these didn't contract very much at all, which is great.
My main issues were that I had a couple of lenses split while on my eyes and there didn't appear to be a specific reason. They were from the same batch, so maybe they were faulty.
I also found that wearing them every day, the lenses lasted closer to 3 weeks rather than the full month as they became loose on the eye surface.
These are good lenses and used carefully are effective for the given amount of time. Not being the most delicate person, I think many of my problems were more due to not being used to how fragile the lenses were rather than the lenses themselves!
