At Affinity Eyewear, we believe that advanced lens designs and a proper glasses fitting are two key elements necessary for comfortable, clear, and superior vision. We offer the best lens designs for any budget with customized fitting of progressive ("no-line" bifocal / trifocal) and bifocal lenses to meet the visual needs of all our patients.
In addition to providing digital single vision, bifocal, and progressive lenses, we also offer prescription polarized lenses which can be placed in any of our frames or an existing pair of your own! If you don't want a separate frame for sunglasses, we have attractive clip on polarized sunglasses offered in a variety of shades, gradients, and colors!
Why buy from us? Here are several measurements included in a glasses fitting at Affinity Eyewear:
The "PD" measurement
PD stands for pupillary distance (the distance between your eyes). It is a great starting point for centering the patient's prescription in the lens. It alone, however, is not ideal for making an excellent fitting pair of glasses.
The Segment Height
This is a critical measurement which dictates where the progressive or bifocal is placed. If the segment height is too high, this means the bifocal is too high, which results in decreased distance vision. If the bifocal is too low, it is difficult for the patient to find the "sweet spot" for computer work or reading.
The "B" dimension
This simply means how large a frame is vertically. That is to say, a large B dimension means a frame is taller. A frame with a large B dimension would be ideal for a progressive lens. A progressive lens or bifocal can still be successfully placed in a small frame if cosmesis is a concern!
