X-ray attenuation by prescription lenses

Area of Science:

• Ophthalmology
• Medical Physics

Background:

• Diagnostic x-rays expose patients to ionizing radiation.
• Prescription lenses are commonly worn by patients during imaging.
• The radiation attenuation properties of lenses are not widely quantified.

Purpose of the Study:

• To quantify the x-ray attenuation of various prescription lenses.
• To assess the potential of photo-gray lenses for radiation protection.

Main Methods:

• X-ray transmission measurements were performed using a standard diagnostic x-ray beam.
• Attenuation was measured for lenses with different materials and prescriptions.
• Specific focus on the performance of photo-gray lenses.

Main Results:

• Prescription lenses exhibit varying degrees of x-ray attenuation.
• Photo-gray lenses demonstrated significant attenuation of diagnostic x-ray radiation.
• The protective effect was notable across different exposure settings.

Conclusions:

• Prescription lenses can offer a degree of protection against diagnostic x-ray exposure.
• Photo-gray lenses are a viable option for enhancing patient eye protection during x-ray procedures.
