“…The first opaque corneal contact lenses contained a hand‐painted iris layer completely encapsulated in plastic with a clear optical zone housing the refractive correction. While these lenses reduced light scatter and glare sensitivity and often improved visual acuity, manufacturing such lenses was technically challenging …”

Ocular pathology that manifests at an early age has the potential to alter the vision-dependent emmetropisation mechanism, which co-ordinates ocular growth throughout childhood. The disruption of this feedback mechanism in children with congenital or early-onset visual impairment often results in the development of significant ametropia, including high levels of spherical refractive error, astigmatism and anisometropia. This review examines the use of contact lenses as a refractive correction, low vision aid and therapeutic intervention in the rehabilitation of patients with bilateral, irreversible visual loss due to congenital ocular disease. The advantages and disadvantages of the use of contact lenses for increased magnification (telescopes and microscopes) or field expansion (reverse telescopes) are discussed, along with the benefits and practical considerations for the correction of pathological high myopia. The historical and present use of therapeutic tinted contact lenses to reduce photosensitivity and nystagmus in achromatopsia, albinism and aniridia are also presented, including clinical considerations for the contact lens practitioner. In addition to the known optical benefits in comparison to spectacles for high levels of ametropia (an improved field of view for myopes and fewer inherent oblique aberrations), contact lenses may be of significant psycho-social benefit for patients with low vision, due to enhanced cosmesis and reduced conspicuity and potential related effects of improved self-esteem and peer acceptance. The contact lens correction of patients with congenital vision impairment can be challenging for both practitioner and patient but should be considered as a potential optical or therapeutic solution in modern low vision rehabilitation.

“…The various designs of modified contact lenses (CL) have been employed as a non-surgical intervention for reducing glare in albinism. As early as 1959, the first opaque corneal contact lenses with a layer of painted iris containing a clear refractive zone was described 52 . Later, Espy reported a scleral CL with painted iris for patients with OA 46 .…”

“…Strong lenses may, in fact, magnify the movement that images pursue over the retina, by increasing parallax. Contact lenses incorporating an artificial iris, may be applicable in aniridic patients (9,20,21,23,24,34,38) and in albinos (31,40). in both cases the lenses must be applied during the early period in which the fixation reflex develops: an improved retinal image may then lead to a better fixation performance.…”
