I was prescribed the eye mask by the consultant who was looking into some minor retina issues I had contracted. Initially I was concerned about how I would sleep whilst wearing a mask which shone lights into your eyes. My worries were unfounded and it didn’t affect my sleep at all. The mask itself is comfortable to wear and doesn’t interfere with sleeping at all. But just as important, the company behind the product are really keen to to ensure the user has a positive experience and listen to any piece of feedback you are willing to give. Over the years, they have been attentive and call on a regular basis to ensure everything is working as it should be. I really can’t think of any negatives in my experience and wouldn’t hesitate to recommend this treatment too anyone who is contemplating taking it up.
