Good but not as "wow" as thee videos show Strong Protan. Bought sunglasses. There is some improvement to the vision of reds. Although with some drawbacks: they kind of tint the rest of the colors. They only seem to work on reflected lights (on emitted lights, like the one of a screen doesn't seem to work). They must be used in open sun to see some effect. At the moment it's the best available option if you want to improve your color vision.

No refund despite their money back guarantee. The glasses made no difference to my son. Despite their money back guarantee, my return request was ignored, more than once, and only accepted once I’d opened a Paypal case. The glasses were returned by Royal Mail tracked but no refund has been received. All correspondence since had been ignored so I’ve had to escalate the PayPal case to receive my £284.00 Incidentally, when I was contemplating purchasing the glasses and asked a question and needed help with filling in the prescription, their communications were excellent, answering every email straight away! I wouldn’t recommend these glasses but if you do decide to purchase them, I’d strongly advise to use PayPal so you’re covered in the event of being ignored, as I have been.

The company is a scam The company is a scam. I think preying upon incurable eye conditions and people desperation to see. Properly is disgusting. The slew of bogus reviews is disgusting, and the level of manipulation this company has gone to, to pull the will over your. Eyes is insane. Avoid this despicable company at all costs.
