Lightweight and Effective
I bought these because I have severe light sensitivity. Wearing special glasses over my own was increasing severity of migraines from light, because I am always in the house. The visor is easy to attach. Although it tends to loosen as the day progressed and I have to retighten, with a simple turn of a knob. The seller was generous and provided 2 additional visors. This made the price for it much easier to accept. I felt if was overpriced. I am satisfied as it gives me a break from light blocking glasses. After a month of daily wear it still looks new.
