Bifocal lenses
As time passes, it inevitably leaves its mark on vision. Thus, with advancing age, vision problems both at a distance and up close become more pronounced, hindering the normal conduct of daily activities. Bifocal lenses are a versatile solution for people who need visual correction for both distance and near vision. These lenses are designed to provide clarity and comfort, adapting to each person’s specific needs.
Bifocal lenses combine two visual corrections into a single lens. The upper part of the lens is intended for distance vision, while the lower part is designed for near vision. This duality allows the wearer to see clearly both distant objects and those in proximity without needing to switch glasses.
Bifocal lenses offer several significant advantages for those who need visual correction for both distance and near vision. Their benefits include:
- simplicity: they provide clear vision for both distance and activities like reading without needing to change glasses;
- easy adaptation: using two distinct focus zones ensures a smooth and quick transition between activities without requiring a long adaptation period;
- comfort: one pair of glasses for multiple visual needs reduces the necessity of carrying multiple pairs of glasses;
- cost efficiency: usually more affordable than progressive lenses, they offer an economical solution for vision correction.
Specification
Shapes
Bifocal lenses have an inset lens (segment) in the lower part, where the near vision prescription is found. Two of the most common shapes are:
- straight segment;
- round segment.
Multifocal
They are multifocal lenses because they have areas with different prescriptions on their surface. The difference compared to progressive lenses is that the transition between zones is visible without intermediate spaces. Essentially, it’s a lens with reading prescriptions inserted at the bottom of the lens with distance vision prescriptions.
Modern Materials
Modern materials used in lens manufacturing significantly reduce the transition between prescriptions. A new type of bifocal lenses is the Bifocal INVISIBLE lenses, which do not involve inserting a segment but instead use free-form processing (point by point) of the lens. This technology allows the creation of a more aesthetically pleasing, almost imperceptible reading segment. Considering the natural ability of the eye to focus on objects at any distance, the optical quality of these lenses is excellent.
