FCAROLYN 6pcs Eye Patch for Glasses to Treat Lazy Eye/Amblyopia/Strabismus (Black)

Brilliant item, just what I wanted. It blocks sight completely, and is an simple but ingenious thing. Only suggestion would be to sell them in different sized packs - this came with a variety of sizes, and I cannot envisage any time when I'd need two patches for a child's use. I'm sure it would do a great job of resting the patched eye whilst making the other do more work thereby becoming stronger. However, I used mine for blocking out vision from an eye that had received laser treatment and was in the healing stage when lots of spider's web-type blood patterns were floating through the vitreous humour and making it difficult using both eyes to read. Did the trick superbly.

Description did not say there were different sizes. Did not find out until the last of the smallest was about to be binned! Let's hope we can get next day delivery on the next lot. They do move easily meaning you have to pull them back over to cover the lens again. You do get what you pay for. So for the price, they're ok.

Thread the arm of your glasses through the holes and it fits perfectly. The only downside as that I can see little holes through the fabric when looking at bright surfaces (or outside) so it's not 100% blocking.I used these after a retinal tear laser surgery when you really can't see much at all out of the eye and this allowed me to block off all that irritating shadow and liquid from the bad eye whilst it recovered and just use my good eye. This made a HUGE difference, so whilst not perfect (not 100% blocking) they do block light not just from the front but also the side.I'm VERY glad I had these to help me through the recovery period. As a beneficial side effect, it also lets others know your vision is impaired - quite useful as you misjudge distances and bump into things.

a cleverly thought out solution to a very difficult problem. The people who thought this through were extremely clever as it matches all the functions of spectacles. They don't touch the eye lid or eye lashes and do the hundred percent job and you are given the option of many sizes for different sizes of spectacles. I would recommend these to anybody who needs an eye patch on either a permanent or part-time basis. Extremely good value for money as well

The small ones are too small and don't cover the lense because they keep sliding back up the arm. The large ones are too big and keep sliding over the other lense. Really poor quality, I cannot possibly recommend.

As another reviewer has said, these start to "fuzz" quite quickly.The description says "Ultra - Thin material, won't touch your eyes..." which is true, but when they start to fluff up, you can pull the fluff off (and there's a lot!) but there are lots of stray fibres which appear very soon which certainly do touch your eyes and irritate them.Easy to see why 6 are in the pack. I wouldn't buy again.

I have been wearing these for 4 weeks so far as I have double vision prior to it being fully sorted out. There are several in a pack which is very useful as I use them over my varifocals, reading glasses and sunglasses. They are easy to put on and the double material means it cuts out the light on one eye completely. They have never slipped or been uncomfortable.

Main issue with these that within 2-3 days the inside the material on the inside starts fuzzing, I guess thats why it's 6 for a cheap price.
