Dummy lenses are placeholder lenses inserted into eyeglass frames. They serve primarily to maintain the frame's shape and integrity during display, storage, and shipping, and to give the frame a presentable appearance.
Essentially, dummy lenses fulfill the following purposes:
-
Shape Retention: They prevent the eyeglass frame from deforming or warping before a customer purchases them and has prescription lenses fitted. Without them, the frame could easily lose its intended form.
-
Protection: They shield the fragile frame, especially around the lens area, from damage during handling, transportation, and display in retail environments.
-
Presentation: Dummy lenses give the eyeglass frame a complete and finished look. This is important for aesthetic appeal when the frames are on display in stores.
-
Fit and Alignment: They aid in ensuring that the frame maintains its proper alignment, making it easier for an optician to fit the correct prescription lenses later.
Often, dummy lenses are made of inexpensive materials like clear plastic, and are not intended for actual vision correction. They are designed to be easily removed and replaced with prescription lenses or non-prescription lenses of choice.
