The effect of the optical design of multifocal contact lenses on choroidal thickness. [PDF]
PLoS ONE, 2018 Studies have found reduced myopia progression with multifocal contact lenses, albeit with an unclear mechanism behind their protective effect. It is hypothesized that the induced myopic defocus of the addition zones of the multifocal contact lenses leads

Terahertz-based system for dehydration analysis of hydrogel contact lenses [PDF]
, 2019 The use of terahertz-based techniques has grown very fast since they are capable of performingevaluations at molecular level, being very suitable for the analysis of biological samples and bioma-terials such as those for contact lenses.
