Bifocal sunglasses: tinted lens with a reading area at the bottom
What Are Bifocal Sunglasses?
Bifocal sunglasses are tinted lenses with two powers in one piece: the upper part is set for looking at things across the yard or down the trail, and a smaller reading area near the bottom is set for close-up print. You look straight ahead to see far and drop your eyes to read. Every frame on this page can take a bifocal lens when you select lenses.A bifocal lens is a lined lens: the reading area has a visible edge, so you always know where the switch happens. That clear border is the trade-off for a wide, steady reading zone with no blending area in between.Three neighbors often get mixed up with them:Bifocal sun readers are the same idea with a plain top. They suit people who see far without help and only need a boost for small print.No-line multifocal lenses blend distance into reading with a gradual change instead of a border. There is no line to see, and the reading zone is narrower.Full-lens reading sunglasses magnify the whole lens, so print is easy but anything past arm's length goes soft.
Top Line, Bottom Line: Which Pair Do You Need?
BYour Rx card has two parts, and they map straight onto the two zones of the lens. The distance line (SPH, CYL and AXIS) shapes the top. The ADD line sets the reading area at the bottom. Look at your card before you look at frames, because it tells you which of these you are shopping for:Both lines are filled in. You need the top and the bottom working. This is the full two-zone pair: enter both lines exactly as written.The distance line reads 0.00, PL or plano, and there is an ADD. You see far on your own and only small print is hard. This is the pair usually sold as bifocal sun readers: a plain top with a reading area below.There is no ADD. A bifocal has nothing to do for you. Rx sunglasses with your distance numbers alone are the simpler choice.No card, but you keep drugstore readers.The number printed on your readers (+1.50, +2.00 and so on) is a rough starting reference for the reading area, not a measurement. The ADD from a recent eye exam is the number to order with.
The Look-Down Map: Will Bifocal Sunglasses Suit Your Day?
A lined bifocal only helps when your eyes drop into the reading area. So the useful question is not how much you read outside, but where the print sits when you do. Sort your outdoor small-print moments into four zones:Lap Zone, well below your chin.A paperback on a beach chair, a seed packet on a garden bench, a tackle tray at your feet. Your eyes drop on their own, and this is where a bifocal feels effortless.Hand Zone, around chest height.Your phone, a patio menu, a golf scorecard, a fishing knot, a price tag at the farmers market. A small downward glance does it. If the line feels a little high or low, frames with adjustable nose pads can be set slightly up or down so the reading area meets your eyes where you actually hold things. Use the Adjustable Nose Pads filter on this page to see them.Eye-Level Zone, straight ahead.The posted hours on a shop door, a trailhead map you are standing right in front of, a gauge mounted at face height. The reading area sits below this line of sight, so you would have to tip your head back to use it.Overhead Zone, above your eyes. A tag on a hanging plant, a label on a top garage shelf, a screen mounted above an outdoor bar. A lined bifocal cannot reach here at all.Keep a rough count for one weekend. If most of your close-up moments land in the Lap and Hand zones, a bifocal fits your day. If most land at eye level or overhead, a lined bifocal will work against you, and distance-only Rx sunglasses plus a pocket pair of readers is the easier setup.
How to Choose a Frame for Bifocal Sunglasses
Leave room under the line.The reading area lives in the lower part of the lens, so very short, narrow lenses leave little space for it. Fuller lens shapes such as square aviator sunglasses, oversized aviator sunglasses, square and round frames give the bottom zone more room.Use adjustable nose pads to fine-tune the line.Pads let the frame sit a touch higher or lower on your nose, which moves where the reading area meets your eyes.Match the material to how long you wear them.TR90 and titanium keep a pair light for a full day outside. Acetate brings deeper colors and patterns like tortoise, with a bit more weight.Size first, style second. Whether you are shopping bifocal sunglasses for women or for men, fit matters more than the label. Start with the Size filter, or choose Not Sure, then narrow by Shape and Color.Try before you add lenses.Use Try On or AR Try-On to see how deep each lens sits on your face. If the lower rim lands high on your cheek, the reading area will feel cramped.
Picking a Tint You Will Read Through
In a bifocal sun lens the reading area is tinted along with the rest of the lens, so the tint you choose is also the tint on your page. Dark tints suit wide-open, bright places such as open water, sand or a sunny ballpark. Under a patio umbrella or a tree, the same dark lens dims small print. If most of your reading happens in partial shade, a medium tint keeps the page brighter. Gray keeps colors closest to how they look without sunglasses, while brown and green add warmth. The tint and lens options available for each frame appear when you select lenses.

Bifocal Sunglasses FAQ
What are bifocal sunglasses?
Bifocal sunglasses are tinted lenses with two zones: the top for seeing at a distance and a reading area at the bottom for close-up print. You look ahead to see far and glance down to read, so one pair covers both outside.
Do bifocal sunglasses have a line?
Lined bifocals do: the reading area has a visible edge where the two zones meet. No-line multifocal lenses blend the zones with a gradual change instead, which removes the border but makes the reading zone narrower.
Can I get bifocal sunglasses if I don't wear glasses for distance?
Yes. If your distance line reads 0.00, PL or plano and you have an ADD, the result is a plain top with a reading area below, the style often called bifocal sun readers. See Top Line, Bottom Line above to match your card to the right pair.
What do I need to order bifocal sunglasses online?
Your Rx card with the distance line (SPH, CYL, AXIS) and the ADD line, plus a frame that fits. If you are unsure of frame size, the numbers printed inside the temple of your current glasses are a good starting point.
Can bifocal sunglasses be polarized?
Polarized film and a lined bifocal can be combined in one lens. The lens options shown for each frame when you select lenses list what that frame supports.
