Hidden Bifocals- No Line, Inner and Blended
March 1, 2018
More and more customers have been seeking hidden bifocals. We created a brand new section and will be adding more styles in the coming months. It's important to note that there are a few types of Hidden Bifocals
All have one thing in common: It appears to others that you are wearing regular glasses. Of course, if anyone took a good look in bright sunlight, they may be able to tell.
- Progressives: (also known as No-Line Bifocals) Beware! No-Line bifocals are NOT simply a bifocal with no line. It is an industry term for something VERY specific. No Line bifocals have THREE strengths. The strongest is on the bottom of the lens, and the weakest is on top. The transition from one strength to the next is gradual, and it will appear to others that you are wearing regular glasses. The gradient tends to be much smoother in progressives. After all, the lens is transitioning from one strength to another slightly weaker strength, whereas straight up bifocals require blending from one strength to NO strength. Pros: Smoothest transition available. Cons: Not good for people who want CLEAR NO STRENGTH on top. You an view our Multi Focal Progressive Readers in this separate category.
- Inner Bifocal: This means the bifocal is placed on the inside of the lens, so when others look at you they generally can't see the line. However, YOU as the wearer will be able to see the line. Cons: Some people are annoyed by the line. This might be what brought you to this page in the first place! For example, when you look distance through the un-magnified top lens, the line in your periphery may bother the heck out of you. Pros: That line clearly demarcates where the clear part ends and the reader begins. There is no "blurry" blended area and some people find it's easier for their eyes to adjust. Our Inner and Hidden bifocals can be viewed in this category.
- Blended Bifocal: The bifocal is also 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. Pros: If you as the wearer can't stand perceiving the bifocal line, you won't have that issue. Cons: There is 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.
When most people call us to ask if we have No Line bifocals, they are usually thinking blended bifocals. Our Inner and Hidden bifocals can be viewed in this category.
