A viewing target for a visual acuity and refraction measurement includes at least one line comprising a width dimension that is below a resolution limit width of a test subject visual acuity, and an adjustable length dimension that is initially set at greater than the RLW of the test subject visual acuity. The micromagnetic device also includes a first magnetic core layer formed above the second insulating layer, a third insulating layer formed above the first magnetic core layer, and a second magnetic core layer formed above the third insulating layer. Similarly, the fabric care compositions preferably have less than about 5% fabric softener actives, more preferably less than 3%, even more preferably less than 1% and are most preferably free of detergent surfactants. The identification method comprises the steps of.
