How do opticians take photos of your eyes?
When opticians photograph your eyes' inner workings, digital retinal imaging (DRI) is used to take images of the back of your eye.
In most countries, the optician operates the machine and takes the photographs, but the images are evaluated by an ophthalmologist..
How does computer eye test work?
An autorefractor or automated refractor is a computer-controlled machine used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses.
This is achieved by measuring how light is changed as it enters a person's eye..
What device is used to look at eyes?
They'll use a device called an ophthalmoscope to look into your eyes.
There are two types of ophthalmoscopes.
One looks a bit like a telescope and is called a panoptic.
The traditional type of ophthalmoscope is more compact and is called a standard head..
What is computer eye testing?
The “very” simplified version of the working.
The actual process of measurement involves sending a fine ray of infrared light into the eye to be reflected back from the retina.
The light sensor in the machine detects the polarisation of the reflected light and compares it against the incident light..
A digital eye exam uses advanced technology to help optometrists perform comprehensive eye health assessments.
Digital equipment can determine your current prescription faster and more accurately than manual measurements.
Online vision tests cannot offer accurate prescriptions for patients that need irregular or high-power prescriptions.
Online vision tests can test the power of eyeglass prescriptions, but are not effective at testing contact lens prescriptions.
Use the online ZEISS Online Vision Screening to check your eyes online.
This online vision test was developed by ZEISS experts to allow you to test your eyes in an easy and fast way – for free.

Next, you will open your eyes as wide as possible and stare at an object straight ahead. A bright flash will be seen when the photograph is taken, capturing high definition images of your retina and optic nerve. The images are displayed on a computer screen for your eye doctor to review with you.

Default computer wallpaper of Windows XP

Bliss, originally titled Bucolic Green Hills, is the default computer wallpaper of Microsoft's Windows XP operating system.
It is a virtually unedited photograph of a green hill and blue sky with white clouds in the Los Carneros American Viticultural Area of California's Wine Country.
Charles O'Rear took the photo in January 1996 and Microsoft bought the rights in 2000.
It is estimated that billions of people have seen the picture, possibly making it the most viewed photograph in history.
