Chin Rest

A chin rest provides stability and ensures that the patient maintains a steady head position during the examination.

Display Screen

A display screen allows the optometrist to view the measurements and results obtained by the autorefractor machine.

Internal Processor

The autorefractor machine incorporates a central processing unit (CPU) responsible for analyzing and interpreting the data obtained from the optical sensors and cornea measurement device.

Objective Lens System

This system incorporates lenses that help gather light and focus it onto the patient''s retina. It includes various lenses to cater to different refractive errors.

Optical Sensors

These sensors detect and measure the light reflected from the patient''s eye, providing valuable data that enables the machine to calculate refractive errors accurately.

Cornea Measurement Device

This device works in conjunction with the objective lens system and measures the reflection of light from the patient''s cornea. It assists in determining the corneal curvature and subsequently contributes to the overall refractive error measurement.
