Bifocal lens replacement is a convenient way to update your vision while keeping the frames you already wear and enjoy. At Rx Safety, you can replace the lenses in your existing frames with new bifocal lenses customized to your prescription, measurements, and vision needs.

Whether your prescription has changed, your current lenses are scratched or damaged, or you’re ready to upgrade your lens material or features, replacing the lenses allows you to refresh your eyewear without purchasing a completely new pair. You keep the familiar fit, comfort, and style of your existing frames while getting new lenses designed for clear distance and near vision.

For many wearers, traditional bifocals remain the preferred solution for dual-distance vision correction. Their clearly defined distance and reading zones provide a wide, consistent near-vision area without the progressive corridor found in progressive lenses.

Choose Your Bifocal Lens Style

Different bifocal designs provide different reading areas and visual experiences. Our custom bifocal lenses include several options to accommodate different vision needs and preferences.

Flat-Top Bifocals

Flat-top bifocals, also known as D-segment bifocals, feature a clearly defined reading area in the lower portion of the lens. Our options include FT-28, FT-35, and FT-45, with the number referring to the approximate width of the reading segment in millimeters.

A flat-top bifocal replacement is ideal for wearers who prefer a traditional lined bifocal and want to maintain a familiar visual experience.

Round Segment Bifocals

Round-segment bifocals feature a circular reading area in the lower portion of the lens. Our options include Round Seg 22, Round Seg 24, Round Seg 28, and Ultex Round 40 with the number referring to the diameter of the near-vision segment in millimeters. A larger segment provides a wider area for reading and other close-up tasks.

This classic design may appeal to wearers who are already accustomed to a round segment or prefer its appearance.

Executive Bifocals

Executive bifocals, also known as Franklin bifocals, have a dividing line that extends across the full width of the lens. The upper section provides distance correction, while the entire lower section provides near vision.

An executive bifocal lens replacement offers an especially wide near-vision area, making it a useful choice for people who spend significant time reading or performing detailed close-up work.

Invisible or Blended Bifocals

Invisible or blended bifocals soften the visible dividing line between the distance and near portions of the lens. They maintain separate focal zones while providing a more subtle appearance than traditional lined bifocals.

Our options include the Blended Bifocal 28, which provide two distinct zones for distance and near vision while softening the visible line of the 28mm reading segment.

When Should You Replace Bifocal Lenses?

If your frames are still in good condition, there may be no need to replace them just because you need new lenses. Rx Safety allows you to replace bifocal lenses in existing frames, giving your favorite eyewear a fresh start. Bifocal lens replacement may be a good option if:

✓

Your distance or reading prescription has changed

✓

You need a different ADD power

✓

Your lenses are scratched, chipped, or damaged

✓

Your lens coatings have become worn

✓

You want to upgrade your lens material

✓

You want to change your bifocal style

✓

You want bifocal sunglasses or photochromic lenses

Your replacement lenses are customized according to your prescription and selected options, allowing you to update your vision while keeping frames that already work for you.

Precise Measurements for Your Bifocals

Accurate measurements are particularly important for bifocal lenses because the reading segment needs to be properly positioned in relation to your eyes.

The segment height, or seg height, determines where the near-vision portion of the bifocal begins. Proper placement allows you to comfortably access the reading area when looking downward while maintaining clear distance vision when looking straight ahead.

Our optical lab uses your prescription and required measurements to accurately position your replacement bifocal lenses for comfortable, functional vision, across a wide range of frame styles, including metal, acetate, rimless, and semi-rimless frames.

Bifocal Replacement Lenses for Your Favorite Frames

Bifocal replacement lenses can be made for many types of eyewear, including metal, acetate, full-rim, semi-rimless, and rimless frames. Compatibility depends on factors such as the frame’s construction, size, shape, condition, your prescription, and the bifocal lens selected.

With bifocal lens replacement from Rx Safety, you can keep the frames that already fit your face and style while updating the part that matters most for your vision. Whether you need a lined bifocal replacement, flat-top bifocal replacement, executive bifocal lens replacement, or another custom bifocal solution, replacing your lenses gives your favorite eyewear a new life.

Frequently Asked Questions

Bifocal lens replacement allows you to replace the lenses in your existing frames with new bifocal lenses customized to your current prescription. Instead of purchasing an entirely new pair of glasses, you keep your frames and have new lenses made for both distance and near vision. This is a convenient option when your prescription changes, your lenses become scratched or damaged, or you want to upgrade your lens type or features.

Rx Safety offers several types of bifocal replacement lenses to accommodate different vision needs and preferences. Options include Flat-Top bifocals, such as FT-28 and FT-35, Round Segment bifocals in different segment sizes, Executive bifocals with a full-width reading area, and Blended bifocals with a less noticeable segment line.

Segment height (seg height) determines where the near-vision portion of a bifocal lens is positioned within your frame. Accurate placement is important because the reading segment needs to align correctly with your eyes.

When replacing bifocal lenses in existing frames, the measurement is applied to the actual frame dimensions so the near-vision segment sits at the correct height when the glasses are worn. Our optical lab uses the required measurements along with your prescription and frame specifications to accurately position the bifocal segment in each lens, helping provide a natural transition between distance and near vision.

Bifocal lenses have distinct zones for distance and near vision, typically separated by a visible line or defined reading segment. Progressive lenses, also called no-line multifocals, provide a gradual transition between distance, intermediate, and near vision without a visible segment line. Traditional bifocals can provide a wider, more clearly defined reading area, while progressives offer multiple viewing distances and a line-free appearance.

Yes. Bifocal lens replacement can be an opportunity to convert existing eyewear into prescription bifocal sunglasses by replacing clear lenses with appropriately tinted prescription bifocal lenses. Depending on your prescription and selected lens options, photochromic lenses may also be available for those who want lenses that automatically darken in response to UV exposure and become clearer again indoors.

Replacing bifocal lenses can be a cost-effective alternative to purchasing an entirely new pair of prescription glasses, particularly if your existing frames are still in good condition. Instead of paying for both new frames and lenses, you can keep the frames you already own and invest in new lenses customized to your current prescription.

Turnaround time for custom bifocal lens replacement can vary depending on your prescription, bifocal design, lens material, coatings, and other customization requirements. Because bifocal lenses require precise prescription fabrication and accurate segment placement, each pair must be produced according to the specifications of your order and existing frames. Check the current service information or contact Rx Safety for the estimated turnaround time for your specific lens replacement.
