In post #7 you said: "...I could go on but but I'm done with this thread..."Glad you didn't mean it.
Sometimes I wish I had a lack of knowledge, but you are in no position to judge that nor is that the issue here.
Unclear why you posted those links. Are you suffering from sunstroke ? We agree on everything except the extent of UV transmission through the eyelids and through protective goggles. The tanning booth sources and consumer sites are divergent from true credible medical sources. The plain truth is that NEGLIGIBLE UV radiation passes through the intact normal upper eyelid. Check the Medline sources, not consumer sites. Negligible = not clinically significant and/or not a cause of pathology.
Please post your source (see message #7) which proves that UV goggles do not substantially reduce UV radiation. Even simple polycarbonate lenses for human eye wear can eliminate 99.9% of all UV radiation, so it is painfully obvious that goggles designed to eliminate UV radiation should do the same or better.

Present status of eyelid phototherapy.

BACKGROUND: Phototherapy for the eyelid has not previously been recognized as a safe and effective treatment of photoresponsive dermatoses of the eyelid, such as atopic dermatitis, vitiligo, psoriasis, lymphomatoid papulosis, and parapsoriasis.
OBJECTIVE: The purpose of this study was to demonstrate the efficacy and safety of this treatment.
METHODS: Two cases are presented to demonstrate clinical efficacy. In addition, a retrospective eye evaluation of seven patients receiving a combined total of greater than 1300 eyelid phototherapy treatments was performed. To determine whether potentially harmful UV radiation is significantly transmitted through eyelid skin, an in vitro study was conducted to measure the percentage transmittance of ultraviolet-visible radiation through five excised eyelids.
RESULTS: In the two cases presented, remarkable improvement occurred without adverse side effects, suggesting that it is possible to deliver incremental UV dosages to eyelid skin to achieve clearing of skin disease. Retrospective analysis of patients’ records revealed no ocular disease from the phototherapy. In vitro eyelid examination produced data that indicated negligible quantities of UV radiation were transmitted through eyelid skin compared with the visible spectrum, in which up to 77% of the radiation was transmitted through the tissue.
CONCLUSION: The combined clinical experience and transmittance data suggest that eyelid phototherapy is a safe and effective treatment in selected patients.
