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.

Good start to a series
Format: Kindle
I delayed reading the series for reasons I don’t remember. But my TBR list is huge so I thought I’d take a shot of this and I was pleasantly surprised. I didn’t think the blurb about it was anything special. But it was a very good book. It took some interesting twists and turns. I am so glad the second book is already out. Because I would not have waited patiently. Very slow burn but good storyline. 🔥🔥/5

A good read
Format: Kindle
Multiple points of view. 3 Alpha men and an Omega male. She is a Beta in training for a new program placing betas in Alpha/Omega packs. Mila is only doing the program for the money to take care of her dad. She wasn't expecting to fall for a pack but when she sees this packs Omega she is done for. There is just something about him. His Alphas are good looking as well. Too bad she is hiding a secret and their government is acting shady. I liked it and can't wait to see where their story goes.

Slightly repetitive but I did love some things
Format: Kindle
I love this type of story. And omegaverse is one of my all time favorite genres. But there are a few things that pulled me out of my enjoyment while I was reading. It was repetitive at times as well as struggled with telling not showing. So we didn’t always feel like we were experiencing things with the main character. There were also some plot holes but they may still be answered in part 2.
Now this isn’t to be said I didn’t enjoy parts of the story. I loved the almost instant love between Mila and Oliver. And how he started changing around her.

delightful read
Format: Kindle
What a delightful read. The characters are awesome, the plot was so good, I loved it. I was intrigued and it kept me wanting more. Told in multiple pov, the book sucks you in and doesn’t let go. I cannot wait to read the next book.

not bad
Format: Kindle
I loved the plot of this book. The characters just didn’t have a lot of depth. The connections and “love” just weren’t communicated very well in the writing. The author didn’t write the sweet psycho trope very well at all either. Lachlan was just a mess of a character.
