When selecting your new frame, it is important to consider how thick your lenses will be in the finished product. There are 4 main factors which contribute to the thickness of prescription lenses:
- The size of the frames (Lens width and Bridge width) and the lens height too.
- The prescription
- The PD - Pupillary Distance
- The overall shape & style of the frames.
Before you choose your new frame, we suggest that you choose a frame that is a similar size to your current frame. Increasing the size of your frames will increase the thickness of your lenses.
If your prescription has recently increased, this will add additional thickness, consequently you might want to consider high-index lenses to counteract this change.
The PD - Pupillary Distance determines the location of the lenses within the frames; consequently, it is essential this measurement is accurate.
Shape & Style
The shape and style of the frames can affect the result; usually, the smaller the frame the thinner the lenses. Full-rimmed frames will hide the edges of the lenses but more so with plastic frames. Semi-rimless and rimless frames are not recommended with higher prescriptions for cosmetic reasons.
It is important to compare how different your last pair of glasses is to your new glasses to ensure the best possible result.
