What is a common reason for lens reflection issues during exam fittings?

Lens reflection issues during exam fittings often stem from improper alignment or coating defects. When lenses are misaligned, the angle at which light enters the lens can lead to unwanted reflections, which can distract the wearer and may affect their vision quality. Additionally, if there are defects in the lens coatings, such as anti-reflective coatings that are not evenly applied or have imperfections, these can also create glare and reflections, impeding the optical clarity.

Proper alignment ensures that the lenses sit correctly in front of the eyes, while well-applied coatings enhance vision by minimizing reflection and improving light transmission. Ensuring that both the alignment of the lenses and the quality of the coatings are optimal is crucial in providing a comfortable and effective visual experience for the wearer.
