bioptic driving [sometimes written with uppercase "o" as "bioptic", or hyphenated as "bi-optic", to differentiate with other types of bioptic] is a method of driving that utilizes the patient’s unmagnified vision in combination with intermittent spotting through a small telescopic system that improves the sharpness of the patient’s far vision. bioptic patients look through just their carrier lens about 95% of the time. when they want magnification, the patient quickly glances through the binocular portion to see details such as street signs, traffic lights and far distant objects. the brief use of the bioptic telescope is much like the quick look all drivers make into their rear view mirror. bioptic driving requires careful fitting of the system followed by extensive training in both the use of the bioptic and behind-the-wheel driver’s training.

the main facility at paranal is the vlt, which consists of four nearly identical unit telescopes (uts), each hosting two or three instruments. these large telescopes can also work together in groups of two or three as a giant interferometer. the eso very large telescope interferometer (vlti) allows astronomers to see details up to 25 times finer than those seen with the individual telescopes. the light beams are combined in the vlti with a complex system of mirrors in underground tunnels, where the light paths must diverge less than 1/1000 mm over 100 metres. the vlti can achieve an angular resolution of milliarcseconds, equivalent to the ability to see the headlights of a car on the moon.
