●LED lamp eliminates troublesome lamp replacement and also makes battery life become as 3～4 times as longer than our older model
●Lever action becomes much smoother by using linear sensor
■The "cornea reflection light coincidence method" is used. This operates by aligning luminous points on the pupils with the measuring line.
■Results are displayed digitally. Three measurements are given : Right, Right + Left, left.
■Results are accurate to within 0.25 mm.
■Measurements can be made for a single eye or for both eyes.
■Possible to measure PD of focusing-point distances ranging from 30cm to infinity.
■Automatically switches OFF one minute after operation is completed, thus conserving power.
■Distances from tops of cornea to lenses of frames can also be measured.
