UV-protective sunglasses for UVA irradiation protection
International Journal of Dermatology
|November 1, 1995
Summary
Many patients undergoing PUVA treatment find recommended UVA-blocking eyewear cosmetically unappealing. This study found that over half of tested sunglasses offered satisfactory eye protection, but wrap-around styles are recommended for optimal results.
Area of Science:
- Dermatology
- Ophthalmology
- Photomedicine
Background:
- Photochemotherapy using PUVA (psoralen plus UVA) requires eye protection to prevent ocular damage.
- Standard UVA-blocking solar shields are often perceived as cosmetically unacceptable by patients.
- This study addresses the need for effective and acceptable eye protection during PUVA therapy.
Purpose of the Study:
- To evaluate the UVA-blocking efficacy of various sunglasses.
- To identify suitable eyewear for patients undergoing PUVA treatment.
- To improve patient compliance with eye protection recommendations.
Main Methods:
- Investigated 34 pairs of sunglasses for UVA protection.
- Utilized a modified method based on Moseley et al. (1988).
- Assessed the 'satisfactory' protection level of tested eyewear.
Main Results:
- 61.8% (21/34) of tested sunglasses provided satisfactory UVA protection.
- Only 53% (9/17) of patient-worn sunglasses were deemed satisfactory.
- High cost or polarization did not ensure adequate UVA protection.
Conclusions:
- Wrap-around solar shields are recommended for optimal eye protection during PUVA treatment.
- Increased availability of cosmetically acceptable eyewear can improve patient compliance.
- Effective eye protection is crucial for patients undergoing photochemotherapy.
