  • The transparent elastic structure behind the iris by which light is focused on to the retina of the eye.

    ‘The cornea, iris, and crystalline lens work together to focus light onto the retina.’
    • ‘The cornea and the crystalline lens refract light that enters the eye.’
    • ‘The most serious injuries involve the cornea and the internal crystalline lens, leading to corneal scars and cataract.’
    • ‘Immediately behind the pupil is the crystalline lens - a transparent protein gel in an elastic sac, which provides the additional optical power needed to bring light to a focus at the back of the eye.’
    • ‘Entering the eye at this location avoids damage to the retina and the crystalline lens.’
    • ‘The main ocular determinants of refraction are the focusing power of the cornea and crystalline lens and the length of the eye.’
    • ‘Urgent magnetic resonance imaging clearly showed dislocation of the crystalline lens into the vitreous, which is being managed conservatively.’
    • ‘An advance that overcomes these problems is the accommodating intraocular lens, which can move in the same way as the natural crystalline lens does before it hardens with age.’

    • ‘Cataract still represents the leading cause of blindness throughout the world; however, the pathogenic effect of solar UV radiation on the human crystalline lens remains controversial.’
    • ‘The crystalline lens in the human eye can change shape, thereby altering its refractive power.’
    • ‘The human eye focuses at different distances by using tiny muscles to change the curvature of the eye's flexible crystalline lens.’
