Near-Sighted Adjustable Focus Glasses (Black) (-1.0 to -5.0)

They are very light weight and fairly comfortable. A bit tricky to get adjusted and seem like they don't hold the adjsutment quite as well as the Adlens glasses. I'm not quite sure why. The mechanism doesn't seem to be moving out of adjustment. It may be a temperature related thing. It's not like they get way out of focus, but I find myself frequently trying to get them a bit better focused.They do work and other than occassionally needing some tweaking, they are pretty good. That said, the in focus zone is pretty small and the area around that is distorted. The trick is to keep your eyes looking straight through the small in focus zone. They take a little getting used to. I bought the Adlens Emergensee glasses at the same time for $10 more plus shipping. Overall, I think the Adlens are better although the nose piece on them isn't as comfortable. On the Adlens you can just look down below the frame for close up viewing, but you'll have to take these off. The Adlens glasses do seem to be a bit "crisper" with less distortion.They call these "self-adjusting" but you have to adjust them yourself. The term is maybe just a bit deceptive or at least technically incorrect. Better it should say "adjustable".I doubt that these will prove to be very durable as they are lightweight plastic, but they do get the job done. Considering the materials and overall construction, I think they are a bit overpriced but they do work and the more I use them, I like them a little better. As they say, these aren't a long term solution to getting real prescription glasses, but they are an adequate substitute and make for a good back up pair at least.

I Have Got Better Built and stronger glass that were Sun Glass with for Free When Filled Up My Gas Tank before. My expectations weren't high for this product but for the money I paid for these glass the glasses would be built a little better. The glasses are hard to focus but in a pinch the glasses could be helpful short term. I bought these glasses has a back up till I can get new glasses because my current pair of glasses could break at anytime. The frames are really cheap and flimsy. These glasses are built like children toy glasses. I paid $29.99 and these glasses are not even close to being worth that price. These glasses aren't even worth $10. I only rated these a 1 star for my review because 1 star is the lowest rate Amazon would let give.

Not durable, barely usable. I had been wearing Superfocus adjustables for almost 3 years and loved them. I would have bought them again if the company hadn't gone out of business. The Focus-spec design is not as usable as the Superfocus. I do not like the separate adjusters of the Focus-spec, The Superfocus single slider was very easy to use.The small usable area of the Focus-spec lens is frustrating. It is OK for close detailed work, but too blurry at the edges of the field of view for computer or TV. The focusing range is not enough to accommodate far vision for me. This would be solved by adding a prescription lens ala Superfocus.The overall quality is low. The light plastic frames are too flimsy for the price. They are flimsier than $5 "readers" from the Dollar store. They aren't a $30 value. The arms both broke off after a couple of days use. These toy glasses do not stand up to even light use.These would make a good $5 keep in the glovebox emergency pair. They aren't up to f\extended wear usage,I am looking forward to the new Adlens/Lenscrafters Focuss line. I hope they are close to what Superfocus delivered. If so they would be worth ten times the cost of Focusspecs.I loved the Superfocus glasses. I hope Adlens develops one as good or better. A good variable focus spectacle is a wonderful thing. Focusspecs just don't deliver!

I had never heard of adjustable eyeglasses before a friend recommended I try them. The optical quality is great (especially for the price) and the best part is that I can focus each eye separately. At this price, I can keep several pairs in different locations so that I have them when I need them. Have to say they aren't the most fashionable glasses, but they really do work great!

They do work.Lens viewing area is very small, so you need to turn your head to get the correct angle to see clear.Made of very cheap plastic. Need to treat them with kids gloves, or they will break.I'm using them to view type on the desktop screen that is three to four feet away.I like to lean back, instead of crunching forward while web surfing.Reading glasses didn't work. My regular glasses didn't work.These are the only negative diopter glasses I could find.I wonder why they don't have them for sale along with the reading glasses in stores.These were cheaper than going to the eye doctor for another set of glasses.
