The relationship between caffeine consumption and near plus acceptance is investigated. Forty subjects monitored their caffeine consumption for three weeks. The subjects were then categorized according to their average daily caffeine consumption as low, moderate, or high consumers.

Plus lens acceptance was determined by improved performance scores on the Kirschner Visual Performance Test (KVPT) . Each subject took the KVPT six times: twice through their habitual near lens, twice through +0.50 D in addition ~o their habitual near l ens , and twice through +0.75 D in addition to their habitual near lens.

Statistical analysis showed no significant relationship between near plus lens acceptance and caffeine consumption.
