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.

Kinda of a cool gadget
Color: Cool White
I really didn't know I needed this until I got it! Easy and quick to recharge batteries (they do not come with rechargeable batteries). Put out enough light for an evening outside around the table

Love the Warm Glow!
Color: Warm White
This light is very easy to install and has 3 different lighting options. I love the warm white light it emits as opposed to a bright white light that could attract bugs at night. Perfect light for patio, deck, camping, golf cart, etc!

It feels cheap and works just okay
This product just feels like it was made on the bottom dollar. It is very cheaply made and the doors to the battery compartment are so fragile it feels like they may snap next time I have to change the batteries. There's absolutely no weather proofing so I wouldn't leave it outside in the rain or heat. That being said, it's fine. It stays put on our umbrella and puts out light, albeit not much light.

Functional and easy to install!
Color: Cool White
This umbrella light is super handy! It hinges open to allow installation around the umbrella pole, so you don’t have to remove umbrella from table to add the light. I like that it can be charged with included USB cord or can use regular batteries. The different light settings are also nice depending on how much light you need or want at the time. We’ll be using this quite often when sitting at the table by the pool this summer.

Different than most on the market worth a try!
I’ve tried a lot of pimple patches and these actually feel different from most of the ones on the market because of the sulfur/OptiMSM ingredient combination. They don’t just cover the spot — they seem to really help bring everything to the surface faster. I had one deep pimple that had been under my skin for so long I honestly started wondering if it was just a scar at that point, and this patch finally helped it come out and heal. The patches are super thin and blend into the skin really well, so they’re easy to wear during the day or overnight. They stick well without feeling harsh on my skin, and I also tried them on my tween sons, who definitely need to wash their noses better sometimes, and they seemed to work really well on their softer skin too without causing irritation. I also love the little travel pouch included. Definitely one of the more effective acne patches I’ve used.
