Amazing. Completely changed my life. I had been struggling to adjust to the new light in my new office and kept struggling with my sight due to loads of different reflections coming off my computer screen, meaning going home I would more than likely get a migraine. I tried these and instantly I noticed a difference; it just made my eyes softer reduced reflection and blue light that was causing horrendous migraines. I very rarely write a review for things but this was a must. No more headaches, no more uncomfortable eyes and sitting in my office is now a dream.
