Most bifocal glasses lens are worn by the more mature people. My mother, grandmother and grandfather all wear bifocal glasses lens. Bifocal syndrome means that one has both short sightedness and long sightedness. That means that images at most distances can’t be seen clearly! It is really quite dreadful, but thanks to Benjamin Franklin, we have the bifocal lens.
Bifocal lens has a separate lens at the bottom half of the glasses lens. The bottom half is to correct for long sightedness, enabling ease in reading books and words off the computer screen. The top half is to correct for short sightedness, where objects far away are now clearer. Due to advances in technology, progressive lens offer some advantages over bifocal glasses lens.
The first advantage is that progressive lens looks better, without a separate lens at the bottom. Progressive lens look just like normal glasses. And due to the smoother transition, the second advantage is that the user will be able to have a smoother transition from the bottom to the upper lens. Thirdly, they are becoming more widely available due to the wider acceptance, with prices expected to go down in future.
