For bifocal lenses, there are different types, such as flat-top bifocals or round-segment bifocals. The optometrist or ophthalmologist will determine the type and power of the bifocal segment based on the patient's visual requirements. The bifocal segment is then incorporated into the semifinished lens, and the lens is further customized to fit the patient's frame and prescription.
Similarly, for progressive lenses, which provide a gradual and seamless transition from distance to near vision, the optometrist or ophthalmologist will prescribe the specific power and design of the progressive lens based on the patient's needs. The semifinished progressive lens is then customized by grinding and polishing, taking into account the frame and the patient's prescription.
The traditional Rx process can be used to create bifocal and progressive semifinished lenses, ensuring that the patient's individual vision requirements are met.
HANN OPTICS is a potential suppplier for semifinished lenses of bifocal and progressive designs.
