Rest easy knowing our opticians are well trained on different lens designs, materials, and how to get you into proper fitting glasses.
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 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 - Black spots in the picture
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 - Blue horizontal line in picture
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 to find the "sweet spot" for computer work or reading leading you to tilt your head up or raise the glasses up to see.
The "B" dimension - Red vertical line in picture
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 if a larger reading area is desired. However, if you are used to a small B dimension don’t go bigger.
