With presenting vision (habitual correction), median visual acuity in the better eye was 6/12 and 6/15 in the worse eye, and 6/6 in both better and worse eyes for the three methods of refraction.
Even a big showstopper, such as Sit Down, You're Rockin' the Boat, allows the song and dance to emerge naturally from the ecstatic vision of a habitual gambler.
Twenty to twenty-five per cent had an anomaly of vision in their habitual playing state, which, in ~ 75% of cases, was due to uncorrected refractive error; such errors are easily treatable using contact lenses.
Vision was measured in the habitual 'sports participation' state, i.e. with optical correction if worn when playing sports.
The attending physician recorded, on a structured form, the type of eye disease, duration of disease, uncorrected vision, maximally refracted vision, vision with habitual correction, and ocular pressure.
Improving your vision is a matter of changing the habitual way you see and use your eyes.
With uncorrected vision, the proportion ranged from none to 18%, with habitual correction from 12%to71%1%, with self refraction from 88%to100%0%, with automated refraction from 93%to100%0%, and with subjective refraction from 94%to100%0%.
Once described by Simon Hoggart as the "furry caterpillar" because of his habitual woolly sweaters, Peter Cheeseman, who has died aged 78, offered a unique vision of the role of theatre in the community.
This study thus demonstrates the vast potential of binocular AO vision testing in understanding the impact of ocular optics on habitual binocular vision.
