Retro style with an almost invisible line blended bifocal is perfect if you want to keep your glasses on all day and adjust your eyes downward through the reader area when you need to read. Special technology places the bifocals on the inside of the lens, so people who look at you can't discern the bifocal. True No-Line progressives where you can't see the line at all cost $200 and up, so this is a great inexpensive alternative.
- if you hold the glasses up and away from you, you'll be able to see the bifocal simply because things appear different and light bends differently through the magnification spot. We often have customers call us right away because they can "see" the bifocal when they first take it out of the box. You are supposed to see it when looking at it in that situation. Place your hand directly inside the glasses, and you can see how the "bifocal" area almost disappears. This is the purpose of blended bifocals: How the glasses will look to others when they are worn on your face, about an inch from your eyes and skin.
- The bifocal is fused to the inside of the lens. However, the line is "smoothed" over, so the transition from reading area to the clear area is gradual. As with all blended bifocals, others will usually not be able to discern that you're wearing bifocals.
- If you as the wearer can't stand perceiving the bifocal line, you will probably love this lens.
- Cons: For some people, there's a downside to these glasses. There's a blurry area between the reader and the clear area. It's only a millimeter or so. However, some people find it interferes with how their eyes adjust.
- Some people expect that the bifocal line goes all the way across the lens. None of the over-the counter bifocals are made in this way. You would have to get them customized at the optician. Indeed, because your eyes converge when you read, it is the reason they don't mass product them in this manner.

- Not impressed Review by D.E.A.
I really wanted to be able to write a good review, but I need to be honest. My Alert "Blended Bifocal" 2.00 glasses came in the mail very efficiently and I was excited when they arrived. Unfortunately, they are far from "blended." You can totally see the rounded half-moon magnifying section, just as if it was an old fashioned bifocal. When wearing them, they are very dizzying and the bifocal line area is very swirly, making me feel cross-eyed. The top portion is fine, with no magnifying, but the bottom half circle area is unbearable (which doesn't go all the way across the lens, like typical readers) Sorry to have to give these a negative review because the company itself seems very professional.
**from DebSpecs: I'm glad that you wrote, because it gives us an opportunity to explain what to expect of the product. When you hold up any bifocal glasses to the light, or away from you, you're going to see the "bifocal" simply because the optics are +2.00 verses no power and the light bends differently. When you put the lens right over your hand (or what they're made for, wearing them on your face) that's when the bifocal is much much less obvious and virtually invisible. Over-the counter bifocal readers never go all the way across the lens. Those are very expensive bifocals, called "executive" bifocals that really can only be purchased in optical stores. Please read the description of the different types of hidden bifocals. "Blended bifocals" DO have a blur spot. The point is so that when other people look at you, the bifocal is even less obvious than "inner" or "regular" bifocals. However, the downside IS that it annoys some people. https://www.debspecs.com/clear-bi-focal/hidden-bifocal.html (Posted on 4/30/2019)
