Question: Is there such a thing as 3 distance 1 lense eyeglasses?
Answers:
If you mean one lens that you can use to see three different distances (far, intermediate, and near) then, yes, there are two types of lenses that can accomplish this.
Trifocal - mostly seen on older folks now that has a distance segment on top and then in two different segments toward the bottom of the lens, separated by lines, there is the intermediate correction and then the bifocal correction for the near.
The other lens, most commonly used these days, is the Progressive lens that has the distance on the top with a narrow channel that progresses down to the bifocal. This lens has many different powers in the intermediate allowing the wearer to see clearly at any distance.
