Using knife\u2010edge lenses this study shows that the calculations are invalid due to the finite size of the eye's entrance pupil and in many instances the scotoma is shown not to exist. The effect noticed in clinical practice is probably largely due to the frame and the edging techniques used which add to the refractive scotoma which is present with high powered lenses, large apertures and\/or small pupil sizes.<\/jats:p>","DOI":"10.1111\/j.1475-1313.2005.00348.x","type":"journal-article","created":{"date-parts":[[2005,12,21]],"date-time":"2005-12-21T10:42:36Z","timestamp":1135161756000},"page":"116-119","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Is the spectacle lens jack\u2010in\u2010the\u2010box phenomenon really due to the lenses?"],"prefix":"10.1007","volume":"26","author":[{"given":"Glyn","family":"Walsh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.
