Ophthalmic Frames: Final Fitting
Final Fitting for Ophthalmic Frames: Checklist & Guide A proper frame adjustment is one of the most important aspects of optical dispensing. A poorly fit frame will result in an unhappy patient. Not only is it likely to cause discomfort, but in cases of stronger powers or high astigmatic corrections, it may even alter the … <a href="https://opticaltraining.com/blog/ophthalmic-frames-final-fitting/">Continued</a>

Anatomy and Refractive States of the Eye: Identifying Ametropia with the Optical Cross
Ametropia Overview The human eye is a remarkable optical system, capable of capturing and processing light to give us the gift of vision. However, when the refractive power of the eye is misaligned with its physical structure, refractive errors—known as ametropia—can occur. These errors include myopia, hyperopia, and astigmatism, each affecting the way light focuses … <a href="https://opticaltraining.com/blog/anatomy-refractive-states-of-the-eye-identifying-ametropia-with-the-optical-cross/">Continued</a>

Ophthalmic Frames: Unraveling the Intricacies of the Measuring Systems
System of Frame Measurements Eyeglass frame and lens measurements are a critical aspect of the optical industry. Frames may be measured using either one of two systems, the Datum System or the Boxing System. The Datum System When measuring an eye size using the datum system, an imaginary line is drawn through the middle of … <a href="https://opticaltraining.com/blog/ophthalmic-frames-unraveling-the-intricacies-of-the-measuring-systems/">Continued</a>

Understanding Eyeglass Prescription Transposition
The Essence of Transposition Transposing an eyeglass prescription involves converting the numerical values from one format to another, without altering the optical properties of the lens. This is particularly crucial when dealing with prescriptions that include astigmatism correction, as they can be written in either a plus cylinder or minus cylinder notation. Astigmatism and Prescription … <a href="https://opticaltraining.com/blog/understanding-eyeglass-prescription-transposition/">Continued</a>
