Introduction
Habitual viewing behaviour is widely believed to be an important contributing factor to the onset and progression of myopia and may be task dependent. The purpose of this study was to quantify the habitual viewing distance of children performing five different tasks on a smartphone digital device.
Methods
The real‐time viewing distanc...
Purpose:
Multizone contact lenses control myopia progression by proposed introduction of myopic defocus. This project investigated how much of the pupil area and how many dioptres of myopic defocus are introduced by different lens zone geometries with near- and off-axis viewing.
Methods:
Ten young myopic adults (18-25 years) binocularly wore fou...
Significance:
Consistent with closed loop models of regulated eye growth, a successful dual-focus (DF) myopia control contact lens focused a significant proportion of light anterior to the central retina in eyes of treated children viewing near and distant targets.
Purpose:
This study examined the optical impact of a DF contact lens during near...
Purpose:
Personal mobile devices such as smartphones are proving their usefulness in ever more applications in tele-eyecare. An inconvenience and potential source of error in these past approaches stemmed from the requirement for the subjects to situate their devices at a distance. The present study aims to clinically validate best corrected visua...
Purpose:
To quantify the amount of myopic defocus, contrast modulation and other optical characteristics of two novel spectacle lenses (MiYOSMART by Hoya and Stellest by Essilor) with the inclusion of lenslets in their designs were investigated computationally and experimentally. This paper examined the hypothesis that despite the non-coaxial natu...
Purpose:
To develop an optical model of a child's eye to reveal the impact of target distance and accommodative behaviour on retinal image quality when fitted with multi-zone lenses.
Methods:
Pupil size, aberration levels and accommodative lag were adjusted for models viewing stimuli at 400, 100, 33 and 20 cm. Distributions of defocus across the...
Novel zonal multifocal contact lens designs are sophisticated. Such lenses can be measured on-eye and ex-vivo using aberrometers, but traditional methods of representing them (e.g. polynomials) are not adequate. Peripheral vision (important for myopia control) requires accurate off-axis measures, which suffer from different error sources: parallax,...
Purpose:
To evaluate the refractive impact of dual-focus (DF) myopia control contact lenses (CLs) on accommodating young myopic adults.
Methods:
Phase 1: accommodative accuracy was assessed in 40 myopic participants. Phase 2: a subset of four subjects who demonstrated accurate accommodation and six who chronically underaccommodated were fitted w...
A combination of human subject data and optical modelling was used to investigate unexpected nasal-temporal asymmetry in peripheral refraction with an aspheric myopia control lens. Peripheral refraction was measured with an auto-refractor and an aberrometer. Peripheral refraction with the lens was highly dependent upon instrument and method (e.g. p...

Purpose: to evaluate the effects of kappa angle and intraocular orientation on the theoretical performance of asymmetric multifocal intraocular lenses (MIOL).
Methods: For a total of 21 corneal aberrations, a computational analysis simulated the implan...
Purpose
High sampling density optical metrology combined with pupil‐ and image‐plane numerical analyses were applied to evaluate a novel spectacle lens containing multiple small zones designed to slow myopia progression.
Methods
High‐resolution aberrometry (ClearWave, www.lumetrics.com) was used to sample wavefront slopes of a novel spectacle lens...
Purpose
The human eye exhibits large amounts (2.5 diopters) of longitudinal chromatic aberration (LCA). Its impact on polychromatic image quality, however, has been shown experimentally and by computer modeling to be small or absent. We hypothesized that modest changes in pseudophakic LCA created by higher and lower Abbe number materials will have...

Significance:
Measurement of ocular aberrations is a critical component of many optical corrections.
Purpose:
This study examines the accuracy and repeatability of a newly available high-resolution pyramidal wavefront sensor-based aberrometer (Osiris by Costruzione Strumenti Oftalmici, Firenze, Italy).
Methods:
An engineered model eye and a di...
Purpose: To evaluate under known, standarized conditions a novel app for remote monitoring of myopia progression in children.
Vision professionals and researchers can use a cloud-connected web interface to remotely access their patients´ data: viewing distance, face illumination and sphero-cylindrical refraction obtained using myopia.app. Viewing d...
Specially developed software (app) was written for handheld electronic devices that uses the device camera and light detector for real-time monitoring of near-work distance and environmental lighting. A pilot study of this novel app employed children using tablet computers in a classroom. Measurements of face-device distance and face illuminance we...
Purpose:
To compare the visually weighted image quality and depth of focus achieved with small-pupil and multifocal strategies for expanding depth of focus of presbyopic or pseudophakic eyes.
Setting:
School of Optometry, Indiana University, Bloomington, USA.
Design:
Computational modeling.
Methods:
The visual Strehl ratio was computed from...
Purpose: Aberrometry is a key tool for evaluating technological advances in eye care, e.g. wavefront-guided refractive surgery. However, the widely used high sampling density COAS HD aberrometer (Wavefront Sciences Inc.) is no longer available. We examined the accuracy and repeatability of a newly developed high sampling density (41μm lens diameter...
Children 8 and under on average spend 2.3h with screen media daily. The average time spent daily with mobile devices has tripled since 2013. Modern mobile devices are fully suited to measure illumination and near work distance in natural conditions at hight acquisition rates. We have developed a new mobile application, called VisionApp, capable of...
Purpose
To develop an objective refraction formula based on the ocular wavefront error (WFE) expressed in terms of Zernike coefficients and pupil radius, which would be an accurate predictor of subjective spherical equivalent (SE) for different pupil sizes.
Methods
A sphere is fitted to the ocular wavefront at the center and at a variable distance...
Purpose:
Part of the large increase of myopia prevalence in children is due to prolonged use of electronic screens (smartphones and tablets) at near-work distances. Myopia progression is correlated with near vision. However, there are no commercially available solutions to measure work distance in natural conditions at high acquisition rates. We de...
Purpose : To obtain fast and accurate measurements of the equivalent sphere (M) and amplitude of accommodation (AA; subjective SAA, objective OAA), taking into account the potential changes in refraction due to the changes of pupil size.
Methods : An empirical wavefront refraction metric (MTR) was formulated using objective (OR) and subjective ref...
Purpose:
Longitudinal chromatic aberration is present in all states of accommodation and may play a role in the accommodation response and the emmetropisation process. We study the change of the depth of field (DOFi) with the state of accommodation, taking into account the longitudinal chromatic aberration.
Methods:
Subjective DOFi was defined a...
Purpose : We propose a new strategy that may permit the visual system to get objective information of the sign of defocus under monocular viewing conditions. It is based on the differences between the retinal images focused in front or behind the peripheral retina produced by the presence of a blood vessel network of arteries and veins in front of...
Purpose : To objectively evaluate the optical performance and simulate retinal images of an extended object in eyes wearing MPlus multifocal IOL's (Oculentis®), that offer an expanded depth of focus. To discover the reasons why some patients wearing those IOL's express discontent regarding their vision quality by using a novel computational method....
Purpose: Recently it has been proven that spherical aberration has influence over the depth of field (DOFi) and the accommodation lag (Bernal-Molina et al., OVS, 2014). We study if the longitudinal chromatic aberration (LCA) also plays a role in increasing the DOFi during accommodation, thus providing an effectively larger range of accommodation....
