Bifocal Designs
Bifocals
The traditional bifocal design has a prescription for seeing at a distance in the top part of the lens. Below that, there’s a visible section that houses your prescription for seeing up close. In the traditional type, you can see a line that separates the two.

In most cases, the bifocal portion is called a “straight top” because the line, as the name suggests, is horizontal across the bottom of the lens (a little lower than halfway down the lenses). In some cases, you may see a half-moon shape with the rounded part at the top, but these are becoming less popular.

Bifocal lenses like these are not available at the drugstore and will have to be custom-made for you.

Trifocals
Trifocals are similar to bifocals and also make a suitable fishing sunglass. What they do is add an intermediate section between your near vision prescription and the one for distance. This, too, is marked by a visible line.

You probably won’t need anything this extravagant just for fishing, but it’s available if you do (or if you plan to take your fishing glasses and use them for other activities for which trifocals work best).

Why reading glasses don’t cut it
Who wants the hassle of putting on and taking off a pair of glasses over and over when they’re trying to have a relaxing outing? Reading glasses could work if you don’t need them to stare into the distance. In most cases, though, they’re not the ideal solution because you won’t be looking down and at close range for long intervals of time while you’re fishing.

You’ll still be able to look into the distance through the upper parts of the lenses, rather than having to look over the frames or remove them as you would with regular reading sunglasses.

Progressives
Progressive lenses are sometimes referred to as “lineless bifocals” but they really work a lot like trifocals. The difference from one part of your prescription to the next is gradual. There’s no line to get used to.
