Auto refractometer is used to determine an individual’s prescription by measuring how light is affected as it reflects through the eyeball. The process is quick and painless for the patient, and the data ensures a baseline to determine the correct eyeglass or contact lens prescription.

Chart Projector

The chart projector is an AC-powered device intended to project an image on a screen for vision testing.

There are important applications for a handheld autorefractor in the clinical setting. A portable but powerful handheld autorefractor such as the SVOne (Smart Vision Labs; Figure 1) can be used in place of a desktop unit if, for instance, the desktop unit malfunctions or needs servicing. The SVOne adds flexibility to the clinic because it is transportable. This can improve patient flow dynamics, taking the testing modality to the patient rather than having the patient leave the exam room to go to a testing station. A handheld autorefractor serves to relieve bottlenecks if a testing station is occupied; it also allows clinicians to carry the technology to satellite offices that may not have the same diagnostic equipment as the main office.lensmeter or lensometer is an instrument used to verify the prescription of eyeglasses or spectacles. Many lensmeters can also verify the power of contact lenses with the addition of a special lens support. The values obtained from a lensmeter are the values specified on the patient's eyeglass prescription: sphere, cylinder, axis, add, and in some cases, prism. It is commonly used prior to an eye examination to obtain the last prescription the patient was given, in order to expedite the examination.

phoropter is a machine that stores all the range of lenses optometrists use to check your eye’s prescription. These are traditionally operated by hand to rotate different lenses into place. An autophoropter is exactly what it sounds like - it automates this process, so that during your eye exam your optometrist will only need to press buttons on a remote control to change to any combination of different lenses. This speeds up the time it takes to work out your prescription leaving more time to thoroughly check the health of your eyes and discuss other aspects of your vision. The autophoropter head can also test a range of near vision aspects to ensure your multifocals and bifocals give you the appropriate focus.

Trial Frame

Trial frame refracting for the primary-care optometrist may seem low tech in today's electronic driven world. Aside from its use by low vision specialists like myself, few still utilize it, as the phoropter, and, more recently, the automated phoropter have pretty much taken its place. That said, you should consider reacquainting yourself with trial frame refracting because the aging population (those age 65 and older) is on the rise, increasing the need for this classic technology.Ophthalmoscopy (also called fundoscopy) is a test that lets a doctor see inside the back of the eye, which is called the fundus. The doctor can also see other structures in the eye. He or she uses a magnifying tool called an ophthalmoscope and a light source to see inside the eye. The test is done as part of an eye exam. It may also be done as part of a routine physical exam.The earliest pioneers created their own mirrors with a slit in the middle to convert the spot into a linear beam. The first electric, self-illuminated retinoscope was developed in 1901 by Wolff. This device included a tiny bulb that directed a spot of light into the eye. Later, different models resulted in the spot being reflected by a plane mirror, or less commonly, a concave mirror.
