The high quality orange coloured filter glasses can be worn independently or over normal spectacles.  They enhance contrast, filter out harmful ultra violet light and reduce dazzling and photosensitivity.  They are especially suitable for outdoor use. The sun shield spectacles fit closely to the head with a darkened upper edge which helps to shield the eyes from light.  The orange filter has an absorption range which gives an effective transmission of light through the filter whilst achieving a significant absorption of UV light.  These orange tinted spectacles are particularly suited as an aid for Diabetic Retinopathy, Photophobia, Cataract and Glaucoma.
