A big question remains as to why myopia progression is only loosely correlated to near work. Not all epidemiological studies could demonstrate a link. The problem arises perhaps because it is still not known what exactly triggers myopia during reading. A classical theory is that accommodation is insufficient (“lag of accommodation”) but the published studies could not convincingly demonstrate that a lag of accommodation precedes the onset of myopia, and the evidence that myopic subjects have larger lags of accommodation is mixed. A major problem is the technologies used to measure the lag of accommodation. First, the devices are typically optimized to measure the best approach to the spectacle refractions (but generating large offsets at near) and second only few studies have taken higher order aberrations into account even though they also determine the plane of best focus. Therefore, a dynamic, binocular aberrometer that can also track pupil size and vergence will be the only approach to finally determine how big the “lag of accommodation” is during binocular reading and whether it might be related to the defocus error signal driving accommodation. The device consists of a single Hartmann-Shack wavefront sensor conjugated with both eyes’ pupil planes through twin periscopes for simultaneous measurements of the dynamics of accommodation, aberrations, pupil sizes and convergence (Chirre et al, Opt Lett 2014, 39). A dichroic mirror transmits the visible light allowing open-view to the subject while the infrared beams are reflected toward the sensor positioned in a lower plane. From the recorded images, both eyes` wave-aberrations, pupil size and relative convergence can be measured in real time (25 Hz).
NOTE temporal contract of FOUR months.
Compensation: Highly competitive salary, including allowances for mobility, and family as well as funds to participate in training activities of the MyFUN network and in (international) conferences.
