Press on-bifocals are stick on prescription powers equivalent to your add or reading prescription. They use static electricity to cling to the backside of your sunglasses, goggles, or other sports eyewear. They are less expensive than regular bifocals, and they offer the advantage of being removable and re-useable. These are perfect for sports as you can put the bifocal segment wherever is most comfortable for you and move it for each individual sport.
For instance, golfers need to bifocal to read a scorecard. However, traditional bifocals are fit so that when the golfer gazes downward toward the ball on the tee, he/she may "catch" some of the bifocal segment distorting the view of the ball. With the press-on bifocals, the segment can be placed to the far right or left side of one lens only so that you can gaze over to read the scorecard, but your line of sight to the ball or the green will not be interrupted.
Or, cyclist often ride with their gaze down toward the street. However, traditional bifocals are fit so that when a rider is on his/her bike looking downward, the bifocal segment is directly in the line of sight. However, with the press-on bifocals, you can place the segment way down low at the bottom of the lens so you can read a map, but your view will not be disrupted.
The press-on bifocals can fit on any lens surface including swim goggles and dive masks. You can remove them when you don't need any near vision. They come pre-cut in bifocal segments. However, the rest of the 2" diameter sheet that the segments are cut out of also have the same power built in it. Thus, you can use this "extra" to cut any shape of bifocal segment that fits your needs. You can also use it as a spare for another pair of glasses or if you happen to lose your other set.
The segments, though, do stick relatively well and are not that easy to lose. They are ultra-thin lenses (only 1mm thick) so you'll hardly know they are there. Press-on lenses won't harm the "carrier" lens, because hydrostatic pressure makes them cling. Never any glue or harmful chemicals. Just plain water, that's all. Upkeep is minimal. Warm soapy water keeps them clean. Made by 3M.
Sizing Information:
If you look at the description on most product descriptions, we have the "eyesize" measurements. Glasses are not measured in sizes like clothes or shoes. Frames can fit differently on each person's nose or ears. The best option is to try for fit. But you can use the "eyesize" to give you an idea of size. You can double the "A" measurement, add the DBL (nose bridge) and get an approximation of width. However, if the glasses are wrap around, the "eyesize" will be bigger since it wraps around the sides. Thus, comparing the eyesize of your regular glasses doesn't always work. If you are unsure about size, you can also contact us for a recommendation. For more information on how eyesize works, check out our eyesize video.
What is a "PD"
PD (pupil distance) tells us how to center the "sweet spot" of the prescription right in front of your pupil for the best vision. If this is not on your prescription, you can contact wherever you made glasses (not necessarily your eye doctor) to get this information. Or see below on how to measure yourself.
What is "Add"
Add is your reading prescription power. If you wear bifocals or progressives, you will need this. If you don't wear bifcoals or progressives (typically people over 40) then you can skip this.
