I've been using these vitamins for years at the recommendation of my optometrist due to how near-sighted I am. They've been very happy with the results, and my retinas continue to look healthy during my yearly checkups. They're definitely not the cheapest, but they do a great job compared to the other eye vitamins on the market. They have way more Lutein in them compared to competitors. The one issue I've had is that I got one bottle where a vitamin must have leaked since everything inside the bottle was the color of the vitamins. What's inside these vitamins tastes terrible, and I just had to down each vitamin quickly each day until they were gone. Luckily this has only happened once in the years that I've been having these vitamins.
