  • Title: The brilliant beauty of the eye: light reflex from the cornea and tear film.
    Author: Goto E.
    Journal: Cornea; 2006 Dec; 25(10 Suppl 1):S78-81. PubMed ID: 17001200.
    Abstract:
    PURPOSE: Light reflex from the cornea and tear film as contributors to beautiful eyes ("eye sparkling") are reviewed. METHODS: A systematic literature review was conducted using "Purkinje-Sanson image," "corneal light reflex," "corneal topography," "corneal wavefront aberration," and "tear interference image" as search terms. RESULTS: Articles on corneal surface regularity and stability and tear interferometry of the precorneal tear lipid layer were reviewed. PS-1 image, that is light reflex from the cornea and tear film, is widely used in practical ophthalmic examination. CONCLUSION: To achieve a brilliant beauty of the eye ("eye sparkling"), it is important that the tear film (aqueous layer) surface is smooth and stable with adequate tear volume and that the tear lipid layer is present in adequate thickness.
