Silver Nanoparticle‐Loaded Contact Lenses for Blue‐Yellow Color Vision Deficiency

preparation of silver nanoparticles impregnated contact lenses

Evaluation of contact lenses for central vision in high myopia.

Contact lenses do not significantly improve central vision as compared to spectacle lenses. I have never rehabilitated a highly myopic patient with subnormal vision by prescribing contact lenses as an optical aid, nor have I ever seen a patient so rehabilitated. My clinical experience confirms theoretical calculations that the effective magnification is not greater than 27 per cent. for a spect...

Disinfecting solutions for soft contact lenses using different color indicators.

PURPOSE The color change reached in two commercial disinfecting solutions for soft contact lenses using new color indicators has been analyzed, and its relationship with the temporal evolution of the hydrogen peroxide concentration, responsible for the disinfection process, has been examined. The results are compared with another commercial solution using a different color indicator. METHODS ...

Extended-wear soft contact lenses for vision studies in monkeys.

The authors have designed and produced extended-wear contact lenses for rhesus monkeys. High-plus lenses to correct neonatal aphakia as well as lenses dyed black for use as occluders to treat amblyopia have been evaluated. Four infant monkeys fitted with soft lenses have successfully worn these extended-wear lenses almost continuously throughout their first year of life. These experiments demon...

acquired color vision deficiency in parkinson’s disease

acquired color deficiency in the tritan axis in parkinson’s disease has already been reported, manifesting itself as impaired performance in various visual tasks. however, its clinical significance has always been controversial. in this study we evaluated the performance of parkinson s disease patients in lanthony 15-desaturated clinical test and for the first time, compared it with the standar...
