ConclusionThese findings suggest that people with visual stress are unlikely to find exactly the same colour to be optimal on different occasions, and raise questions about the need for precise colour specification in tinted lenses for visual stress. (Source: Ophthalmic and Physiological Optics)

Saccades and fixations in children with delayed reading skills
ConclusionsEye movements in children with delayed reading skills are quantitatively similar to those found in children without delayed reading skills. These findings suggest that, in these children, delayed reading skills are not associated with eye movements and further question interventions targeted at improving eye movement control.

Effect of simulated refractive error on adult visual acuity for paediatric tests
ConclusionAlthough the Cardiff Acuity Test provides an easy method for VA measurement in infants and toddlers, there is a considerable overestimation of VA compared with recognition acuity tasks particularly in the presence of defocus. A simple correction factor (of for example three lines overestimate) cannot be applied to Cardiff acuity measures as there is increasing over‐estimation of VA with increasing defocus. Infants with significant refractive error may fall within normal visual acuity ranges for the Cardiff Acuity Test. (Source: Ophthalmic and Physiological Optics)

Drilling into the functional significance of stereopsis: the impact of stereoscopic information on surgical performance
ConclusionsThe data confirm that dental practitioners use stereopsis and its presence results in improved dental performance. It remains to be determined whether individuals with stereo‐deficits can compensate adequately. Nevertheless, these findings suggest an important role for stereopsis within at least one occupation and justify the design of simulators with 3D displays.

The corneal nerve density in the sub ‐basal plexus decreases with increasing myopia: a pilot study
ConclusionCorneal nerve density in the sub‐basal plexus decreased with increasing myopia. This could have implications for corneal surgery and contact lens wear in this patient population. (Source: Ophthalmic and Physiological Optics)

Fourier analysis algorithm for the posterior corneal keratometric data: clinical usefulness in keratoconus
ConclusionsFourier decomposition of posterior Keratometric data provides parameters with high accuracy in differentiating SKC from normal corneas and should be included in the prompt diagnosis of KC. (Source: Ophthalmic and Physiological Optics)

Optical coherence tomography predicts 4 ‐year incident diabetic neuropathy
ConclusionsA lower retinal thickness at the parafovea and a higher BMI can predict 4‐year incident neuropathy in patients with diabetes, with acceptable diagnostic accuracies. This OCT‐derived measure may serve as a potential ophthalmic marker in the screening of patients at risk of developing DPN. (Source: Ophthalmic and Physiological Optics)

Attenuation of short wavelengths alters sleep and the ipRGC pupil response
ConclusionsThe use of short wavelength‐blocking glasses at night increased subjectively measured sleep quality and objectively measured melatonin levels and sleep duration, presumably as a result of decreased night‐time stimulation of ipRGCs. Alterations in the ipRGC‐driven pupil response suggest a shift in circadian phase. Results suggest that minimising short wavelength light following sunset may help in regulating sleep patterns.

Effectiveness of portable electronic and optical magnifiers for near vision activities in low vision: a randomised crossover trial

Childhood exposure to constricted living space: a possible environmental threat for myopia development
ConclusionsAxial length in children and childhood refractive error were associated with high population density and small home size. A constricted living space may be an environmental threat for myopia development in children. (Source: Ophthalmic and Physiological Optics)

The incidence and predictors of depressive and anxiety symptoms in older adults with vision impairment: a longitudinal prospective cohort study
ConclusionsThis study shows that the incidence of subthreshold depression and anxiety in older adults with vision impairment is twice as high compared with older adults in general and confirms that depression and anxiety symptoms fluctuate over time. It is of great importance that low vision rehabilitation staff monitor older adults with vision impairment who are most vulnerable for developing these symptoms, based on the risk factors that were found in this study, to be able to offer early interventions to prevent and treat mental health problems in this population.

The difference between cycloplegic and non ‐cycloplegic autorefraction and its association with progression of refractive error in Beijing urban children
ConclusionIn this sample, the children's DSE was found to be increased as the hyperopic refraction increased. Furthermore, greater the DSE was associated with the progression of refractive error among the myopic children, but not with the onset of myopia. (Source: Ophthalmic and Physiological Optics)

Change in over ‐refraction after scleral lens settling on average corneas
ConclusionDespite a significant change in the central corneal clearance due to thinning of the fluid reservoir as the scleral lens settled (an average decrease of 83 μm after wearing the lenses for 6–8 h), there was not a statistically significant change in the subjective over‐refraction (sphere, cylinder, and axis) or best sphere or visual acuity. This study has confirmed that there is no link between reduction in central corneal clearance and change in over‐refraction for average corneas. (Source: Ophthalmic and Physiological Optics)
