 In most jumping spiders , the main eyes focus accurately on an object up to about 75 cm away . : 51 , 53 However , P. schultzi does not react at all to objectives when the light is under 100 lux . Between 100 and 500 lux , it detects and approaches the objective from distances up to 6 cm , from 500 lux to 1500 lux , its response distance increases gradually to a maximum of about 10 cm , and stronger light causes no increase in the response distance . For comparison , <unk> auricoma swivels towards a movement up to 75 cm away and approaches targets from about 20 cm . Perhaps P. schultzi gains little from being alerted to objectives at distances because this spider moves so slowly that it is very unlikely to reach a more distant target in time to catch it . : 37
