1.49 Flat top Bifocal Lens Prescription Eyewear Lens
A flat-top bifocal lens features a D-shaped reading segment positioned in the lower part of the lens. The top of this segment is a straight horizontal line, creating a distinct separation between the distance (upper) and near (lower) vision zones. It is a popular design that provides a clear, wide area for reading while allowing easy adaptation due to the noticeable divide. The main line is visible to others. These lenses are a classic and practical solution for presbyopia.
