Background. Eye protection with uva‐blocking solar shields is recommended on the day of puva treatment and the following day for our patients; however, many patients found this eyewear cosmetically unacceptable. 

Eye protection for ultraviolet B phototherapy and psoralen ultraviolet A patients

Eye protection used for phototherapy patients was tested and current practice concerning eye protection in a sample of UK phototherapy units was established.

Ultraviolet protective properties of branded and unbranded sunglasses available in the Indian market in UV phototherapy chambers.

All branded sunglasses provided good protection against UVA penetration, but UVB protection provided by both branded and unbranded sunglasses was not satisfactory.

The Role of Ultraviolet Radiation in the Ocular System of Mammals

Exposure to low levels of light in the UV spectrum has been found to regulate the growth of the eye and lack of adequate exposure may increase the risk of development and progression of myopia.

Adequacy of Ultraviolet Protection of Children’s Sunglasses

Even the least expensive children’s sunglasses now meet the recommended safety criteria for filtering UV radiation and that parents can trust labeling claims regarding UV protection, in contrast to previous studies.

Does the Eye Benefit From Wearing Ultraviolet-Blocking Contact Lenses?

There is a need for the development of a scientifically rigorous, clinically applicable ocular protection factor metric, based not only on the transmittance of eyewear but on the protection afforded from the total UVR field and the length of that exposure.

Photoprotection: a Review of the Current and Future Technologies

This review focused on the technological and scientific aspects of photoprotection using sunglasses and clothing while attempting to dispel some of the misconceptions about sunscreens.

UV transmittance in market place sunglasses and their adherence to established standards.

The study did find sunglasses that offered inadequate UV protection, leading to the conclusion that there are sunglasses in the Metro Vancouver market that are inappropriate for standard UV protection.

Guidelines for the use of phototherapy and photochemotherapy in Ireland

ConclusionBoth PUVA and UV-B phototherapy are extremely effective treatments for many skin diseases. Both have known hazards and therefore require careful assessments of patients’ suitability and

Photoprotection: part I. Photoprotection by naturally occurring, physical, and systemic agents.

Do brands and prices of sunglasses ensure adequate Uv-radiation protection?

The function of the human eye is to receive electromagnetic waves and transform them into electrochemical signals, which interpreted by the brain create the sense of sight. However, its capacity for



Eye protection in psoralen photochemotherapy

There is a wide variation in the UV absorbing power of sunglasses although adequate protection against solar UV‐A can be achieved with some, but not all, polarizing material.

Lenticular psoralen photoproducts and cataracts of a PUVA-treated psoriatic patient.

Psoralen photoproducts were identified in association with cataracts in a psoriatic patient several years after oral methoxsalen plus ultraviolet A light (PUVA) therapy. Patients should be required

Photoprotection of the eye in PUVA therapy

Photochemotherapy with psoralens, now widely used in the therapy of psoriasis, vitiligo and mycosis fungoides, has been proposed to have the capacity, during long‐term therapy, to induce ocular

The suitability of sunglasses used by patients following ingestion of psoralen

The types of eyewear which patients on photochemotherapy have obtained, and their suitability for providing adequate protection are investigated, are determined, highlighting the need for increased awareness of the problem of ensuring that suitable protective eyew wear is used.

A retrospective study of cataract formation in 96 patients treated with PUVA.

No patient developed cataract during the PUVA treatment period and these findings were found to correspond to those in a "standard population".

Photochemotherapy of psoriasis with oral methoxsalen and longwave ultraviolet light.

Abstract Oral administration of a photoactive drug, 8-methoxypsoralen (methoxsalen), followed by exposure to a high-intensity, longwave ultraviolet-light system resulted in complete clearing of

Ocular findings in patients treated with PUVA.

This 5-year prospective study of ophthalmologic findings in 1299 patients treated with oral 8-methoxypsoralen photochemotherapy (PUVA) for psoriasis failed to demonstrate a significant dose-dependent increase in the risk of developing symptomatic cataracts, but there was a small increase for development of nuclear sclerosis and posterior subcapsular opacities among patients who received at least 100 PUVA treatments.

Potential ocular complications from PUVA therapy and their prevention.

It is demonstrated that this drug can be found in lenses of rats injected (intraperitoneally) with 4-8 mg/kg of 8-methoxypsoralen (8-MOP) and that its presence can lead to a photosensitized enhancement of lenticular fluorescence.

Cutaneous and ocular side‐effects of oral photochemotherapy: results of an 8‐year follow‐up study

‘PUVA lentigines’ were found in 46% of the patients, most frequent in patients currently being treated and in those who had received high cumulative UVA doses, but persisted for up to 7 years after discontinuing therapy.

Optical Properties of the Skin and Eyes

The first law of photochemistry (Grotthus-Draper law) states that no photochemical (or subsequent photobiologic) reactions can occur unless radiation is absorbed. The biologic effects and microscopic
