- They are simple to insert into one's eye. The images are sharp and crisp. When worn all day, your eyes won't get dry. I work 8 hours a day at the computer with no discomfort from my contacts; the most important thing is to remember to blink. The lenses in this product are quite individualized, and the ease with which they fit on your face will vary from person to person. For my needs, I find that Bausch & Lomb PureVision 2 is an excellent choice.
- There are no downsides to the glasses themselves for me. Optician shops have one major flaw, and that's their overpriced services. It's a relief that Amazon exists because its prices can be up to 1.5 times lower than those at upscale optical shops.
