Lenses
Bifocal 28 lenses are designed for both distance and near vision, with a visible segment line generally positioned around the lower eyelid area to separate distance vision from near magnification.
They provide a practical presbyopia lens solution for users who need clear far and near viewing, including higher vision corrections at an economical price.
Coating Options
- Designed for presbyopic users who need clear distance and near vision in one pair of lenses.
- Features a 28 mm near segment for reliable reading and close-up viewing.
- A practical choice for users who prefer a defined near zone instead of a progressive lens design.
- Available in multiple index and material options, including clear, photochromic, polarized, and polycarbonate lens materials.
