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.

Interesting, but no Lewis
Format: Paperback
Some books can be completely conveyed in about eight sentences or a couple paragraphs. This is one of them. Everything else beyond the core thesis is unnecessary or repetitive. This book probably would have made a good article.
Wright is a well known Pauline expert, but in this book he takes a step out of his comfort zone.
I usually find Paul rambling and confusing enough, so I look to experts like Wright to clarify Paul for me. But in this book, Wright seems to put on his Paul hat and just reiterates Pauline gobbledy-gook. Throughout, he presents long passages comprised solely of Pauline quotes.
This book is billed as an updated version of C.S. Lewis’s “Mere Christianity.” Both Wright and Lewis are seeped in their Anglican tradition. But where Lewis looks at the various Christian denominations and identifies what’s common and good among them all, Wright sees differences and insists they are all wrong. In alienating evangelicals on the one hand, and Catholics on the other, Wright suggests that to be Simply Christian you must abandon your faith traditions that are at odds with his. I can’t imagine Lewis taking this tack.
I give this three stars, for its clear style, for being thought provoking, and for its call to personal introspection.

Great Daily Vitamin
Size: 100 Count (Pack of 1)
I needed a daily vitamin but didn't know where to start, so this was my 1st choice. I don't know specifically what I was lacking in my daily diet, but within a week of taking these, I felt much more energetic than before. Been using them for approximately 2 months now and I will be purchasing them in the future. Pricing is within reason.

Big but smaller than most
Size: 100 Count (Pack of 1)
Good overall vitamin that isn't too big to swallow. No stomach issues, no increased energy, just trying to get my vitamin D up to a good level and adding other vitamins I need is helpful to reduce the number of pills taken each day.
