متن کاملRelationship between spectral transmittance and slit lamp color of human lenses.
PURPOSE To study the relationship between subjective lens color as observed with slit lamp biomicroscopy and spectral transmittance of the lens. To propose a model for this relationship to derive quantitative information on lens pigmentation from slit lamp observation. METHODS Twenty-nine normal lenses, from donors aged 14 to 86 years, were used. The fraction of light transmitted from a narro...
