What are FL-41 lenses? FL-41 is a specialized tint applied to lenses, scientifically proven to block specific wavelengths of light that trigger eye pain, dizziness, and headaches. These lenses are widely used as a therapeutic tool for people managing photophobia, post-concussion syndrome, and migraine relief.
The Science
Why FL-41 Works
Blue-Green Light Blocking These lenses filter out a significant portion of blue and green light — specifically in the 480–520 nm range — which are the most common wavelengths to trigger light sensitivity, eye pain, and headaches.
Soothes Fluorescent & Screen Glare Originally developed by researchers to mitigate the harsh, flickering glare of fluorescent lights in office settings and from computer screens — some of the most persistent everyday triggers for photosensitive individuals.
Reduces Symptom Frequency Clinical studies have shown that FL-41 filters can significantly reduce the frequency and severity of migraines in people who experience light-triggered episodes.

Clinical Evidence
What Studies Have Found
Clinical studies examining FL-41 filters have reported meaningful improvements in migraine frequency and light-triggered discomfort for photosensitive individuals.
74%
fewer migraine attacks reported in studies
76%
improvement in light-triggered discomfort
80%+
reduced overall headache impact reported
Results vary by individual. These figures are based on observational clinical studies involving FL-41 lens filters.

Worth every penny.
Size: 2'6" x 5', Color: Black
It has been my experience that this rug and this company is fabulous if you need or if you want something that’s rich well-made well thought of sheepskin rug you can’t go wrong with this company they take pride in their work I mean by this if you want a sheepskin rug buy from this company. This was the one that I bought and I cannot tell you how gorgeous it is. It saves money because it costs money when you buy cheap you buy twice you buy this. You can forget about it. That’s how good it is.. The weight is perfect. The color is rich and the price there is really no price for something. That is excellent because I’ve been looking around for rugs like this for different creations and decorative tableau and there’s a lot of junk out there..

Not as pictured, but ...
Buyers should note that the advertised photo shows a white rug with gray tips, but the rug I received has a lot of yellow in. Despite the difference, I've decided to keep it because it is a beautiful rug and very soft.

This rug is a fabulous quality for the price!! Thick, soft, great looking. They ship it with a brush and a storage bag... highly impressed. This is my 3rd fur shag from this company. I have 2 cream ones in my master. Im going to order a black one too, just to change it up.
Zero smell, functional, nice size, durable... im in love!! It would look very cool on a chair, the back of a couch next to the FP, or even on a bed.... authentically pleasing for sure.

Absolutely gorgeous! Quality is excellent. I purchased three prior to this from different companies, and returned them. Finally came across this company and truly love the texture and look. This pelt is real sheepskin, NOT felt backing like some. The real deal.
