Michael K. reviewed Qualia Vision
Just started this product, however, I do notice an improved "sharpness" and visual acuity.
Vision study
I noticed a definite increase in being able to focus for long periods of time on the tasks at hand. Experienced more energy during the day and had no problem sleeping at night. Looking forward to the next few weeks to see if the benefits continue to increase.
Highly Recommended
Seems to be helping with my eye fatigue and dryness. Very good and balanced product.
