Product Info

Notice: Crystal Monthly lenses have been discontinued. 

Why are you discontinuing Crystal Monthly?

Contact lens materials advance constantly, and the Crystal Monthly material is now an older generation material. Our Optometric advice is to swap to a newer generation material like Crystal Comfort - which will let a lot more air to your eyes and keep your eyes healthy in the long term. They are a little more expensive (note the pack size is 3 lenses), but we think it is worth it for the health of your eyes.

An excellent alterative are daily lenses. The cost of these have now fallen to such an extent, that there is little financial reason to stick with monthly lenses. Solutions are expensive and the convenience is significantly better with a daily lens. We recommend Crystal Aqua daily lenses.

Crystal monthly contacts

I have bought the Crystal monthly contacts for years now and have found them to be a quality product. My reordering them several times speaks for itself. Contactlensesplus has always gotten me my order quickly and correctly.

Simple to use and great vision!

This product is so simple to use, they glide easily onto my eye. My eyes are never dry even when using them all day. Vision is great. I definitely recommend using this product and I always buy the same ones again and again.

I used the daily version for a month and they were great no problems at all.
I thought I would try the monthly ones as more price friendly.
I bought some Tesco multi purpose solution for them, no one seems to mention what solution they use with these !
Any way every day when I take the lenses out one eye or the other feels like it has got some grit or something under my top eyelid and its very sore and itchy to the point I cant open my eye.
They are fine whilst wearing them its just after removing them.
I don`t know if there is any difference in the actual lens to the daily one or whether it is the solution am using .
I am assuming it maybe solution as the daily ones were fine before hand. I wonder can you buy the solution that the lens in packaged in ?
also has what solution do you all use with yours ?
Editors Comment: It is liable to be the solution - the lenses are the same material.
Not all Multi Purpose solutions are the same, and it is possible that the one that you are using is causing an allergic reaction. This presents under the top lid and has the symptoms you have described. The daily lenses come in sterile saline, so would not cause any reaction - however, you cannot store lenses in saline overnight, as it has no anti microbial or sterilizing properties, so you are exposing yourself to a high infection risk.
I would try another multi purpose solution, possibly Complete Revitalens Multi Purpose solution. You can get it in a travel pack to try, before you buy a large bottle. ( )
However, you may want to go back to dailies for a couple of weeks to clear up any lid problem. If your lids don`t get better, see your optometrist for a check up.

Amazing for price

great value

Made my eyes felt dry to start with. But seemed to have got used to them now and they feel no different to the biomedics i used to wear. I would recommend them but you may take a few weeks to adjust.

I brought them last year and I still order the same ones. They are so comfortable and they don't dry my eyes that quickly. I would recommend it to anyone who is on a budget and are looking for some good quality lenses.

Cheap and Wonderful!

Looking at the price tag for the 6month, i really didnt have much hope for these but been using them for about 2weeks now and i goota say they are as good as my older and more expensive ones. My last ones was around 70quid for 6months nd these were for 15quid. i use them for around 14-18hours a day nd i have to say they are equally as good as the more expensive ones. Perfect!

Amazing!! I recommend everyone who needs contact lenses to give them a try, they might work for you. I bought only one box because I have the same prescription for both of my eyes. the first pair were gorgeous. However, I noted that the second pair, one of them I can see very clearly but the other not too much, I`m not sure if this is from my eye sight or the left contact lenses, because I can still see clearly with my glasses.
I was wondering, should I replace the left lens with a new one and throw it away?
Editors comment: Please replace the lens left and see if the new fresh lens is any better. Please contact customer support for a replacement lens so that you are not short.

Not great but what do you expect for the price...

I am a backpacker traveling around Canada right now and needed a new supply of lenses and came across these. The price grabbed me and although they had mixed reviews a lot of positive ones swayed me. Initially they are very comfortable and for the first few days i was very happy. but very soon they became dry and uncomfortable, there is nothing worse than being out and about and your eyes are feeling irritable. also they are very fragile, I have ripped 4 of them now and i assure you i have been very carful with lenses. overall i am not very impressed and will now have to find some over here in Canada :(

Suprisingly Brilliant

I have worn these lenses now for over a year and my partner has recently changed from her standard £20 a month lenses to these.
All I can say to everyone is to try them, I was so surprised by how comfortable they are, how long you can wear them before dryness and blurred vision occurs (easily 10-12 hours). I will never ever use any other lens as long as these lenses are around, they are a fantastic product which at the price you cant really go wrong!
The only thing I would point out is they are quite a fragile lens, I have torn quite a few cleaning and storing them, it may just be me being heavy handed though!

I decided to try these as like everyone else my budget is taking a hit at the moment I was paying £13 p/m for lenses that were okay but after 8 hours wear had to come out. I bought these ones just to try and received 6 months supply for £14!! Not only that but they are incredible. They go in and come out easier, they let through more oxygen and if you fall asleep do not fuse to your eyeballs. I have worn these for 16 hours without eyedrops. My new lens of choice.

Love them! Great Value!

I work mostly 12 & 16 hour shifts & I've had no problem with them holding up the entire time. They are very comfortable, I think they are even more comfortable than other 'name' brands. I have not had any trouble with them tearing. This is my 3rd time ordering them. Excellent value.

Great lenses!

Tried these after my current lenses became discontinued. For a budget lens they are amazing. I have dry eyes and I find them very comfortable to wear, sometimes for 14 hours a day! They last well and I've not had any issues with quality. A fantastic buy.

Cheap price, and good , but they don`t let lots of oxygen through

I`ve been using these for a while and found they were fine. The price is truly amazing.
When I visited my optician he was concerned as he had never heard of them. A key parameter is the DK value. This is the amount of oxygen they let through to the eye. Too little oxygen and blood vessels can start growing that can eventually blind you.
Daily lenses typically have a DK value of 9. These monthly lenses have a DK value of 20. For reference, Biofinity Silicon monthly lenses have a value of 110.
So, they are cheap but don`t let lots of oxygen through, and as I have dry eyes, I`m not going to risk my eye sight, so am going back to silicon lenses.
I`d rather pay more and not risk my eyesight.
Editors Comment: Crystal Monthly have a DK of 20, in common with other brand name monthly lenses with this material i.e Biomedics 55, Soflens 59. One day lenses do NOT have a low DK of 9, but are commonly 20 DK and up i.e soflens 1 day is 20 DK.
All research shows that this level of oxygen transmission is totally safe for daily wear up to 16 hours a day.
It is mainly lenses that contain silicone that have high DK levels, and these are primarily used for overnight wear, or for those customers that have particularly high oxygen requirements - or have had previous problems with, as mentioned above blood vessel growth.
The DK level has no influence on dry eyes - in fact the higher the silicone level, the worse they can be for dry eyes, as silicone is essentially a hydrophobic material.

pleasantly surprised!

I was sceptical because of my sensitive eyes and the price of these, but fingers crossed,so far, they're great. A little dry after 8 hours of screen work under air con but thats something I've never been able to get away from. Great paired with Bauch & Lomb multi purpose solution, give em a go!

Great value, great product

Very comfortable to wear. Great value.
Made in China, I was abit hesitant to try at the start. So I purchased just a few. 12 months on and I'm still using this brand. I regularly do check ups with optometrist, and my eyes are healthy.
Items are legit and sterile.
I highly recommend.
