Specification of a plano air-spaced liquid goggle lens.

<p>Specification of a plano air-spaced liquid goggle lens.</p

Optimum performance allowable by a goggle lens correction: On-axis optical quality gain OQG of various liquid lenses via corneal index matching optical correction.

<p>The stairs function corresponds to the alternative solution of a ‘non-corneal matching index’ with a 2-element air-spaced goggle lens. The performance by indirect optical correction at various pupil diameters appears on the upper axis.</p

Robustness to lens fitting errors: Wide-angle resolution achieved for a 2-mm pupil diameter over a +/-10 degree field angles using a tunable artificial cornea alone (red symbols) and in combination with a conjugated adaptive plano-element (blue symbols) conjugated to the pupil of the eye, as a function of a) decentering and b) tilting of the goggle lens with respect to the eye pupil.

<p>The black and blue dashed baselines indicate the performance achieved using a single AO corrector conjugated to the eye pupil and the cornea, respectively. Below those 2 baselines, the performance of an adaptive correction using a single plano-element dominates an artificial cornea correction. Note that association of AO with an artificial cornea brings an outstanding performance benefit for wide-angle images, as compared to an artificial cornea alone and a single AO corrector alone.</p
