Effective graded refractive-index AR coating is designed with SiO2, MgF2, and ITO films. Mean reflectance 1.67 high index lenses pdf the AR coating was lower than that of the commercial AR coating.
The blocking of the harmful high energy visible light is more effective than the commercial AR coating. The reduction of optical reflection is important for many applications such as solar cells and lenses. ITO thin films for high refractive-index polymer ophthalmic lenses. The effective graded-RI AR coating is fabricated using the E-beam evaporation system. The mean reflectance of the effective graded-RI AR coating lens was measured to 2. Also, the blocking of the high energy visible light is more effective than the commercial multi-layer AR coating lens. It is known that the high energy visible light caused retinal damage.
The ability to change the maximum reflectance band of an AR coating by simply changing the film thickness is advantageous for other potential applications.

Extended depth of focus contact lenses vs. Lentes de contacto de profundidad de foco extendido vs. Analysis was performed considering eyes with three different inherent aberration profiles: five different pupils and five different lens decentration levels.
Lens performance was relatively independent to pupil and aberrations but not centration. Contrastingly, AOMF demonstrated distance centric performance, most dominant in LOW followed by MED and HIGH designs. AOMF lenses were the most sensitive to pupil, aberrations and centration. TFRIQ performance, particularly at intermediate and near, without trading performance at distance. When compared with AOP and AOMF, EDOF lenses demonstrated reduced sensitivity to pupil, aberrations and centration. With the through focus retinal image quality as the gauge of optical performance, we demonstrated that the prototype EDOF designs were less susceptible to variations in pupil, inherent ocular aberrations and decentration, compared to the commercial designs.
To ascertain whether these incremental improvements translate to a clinically palpable outcome requires investigation through human trials. 21 vergencias, que oscilaron entre -0,5 y 2D, en pasos de 0,125D. Se llevó a cabo el análisis considerando los ojos con tres perfiles de aberración diferentes: cinco pupilas diferentes y cinco niveles de descentramiento de lentes distintos. El desempeño de las lentes fue relativamente independiente de la pupila y aberraciones, pero no del descentramiento. Por contra, AOMF demostró un rendimiento céntrico en visión lejana, más dominante en el diseño LOW, seguido de los diseños MED y HIGH.
