What Equipment Is Used in A Standard Eye Care Test 

Just as you are required to go to the doctor frequently for a check-up to guarantee your body is well, it’s vital to go for eye exams to guarantee your eyesight is in tip-top shape. During an eye checkup, a certified oculist or ophthalmologist will utilize a range of special tools and methods to assess how well you can see. Let’s go through the standard optical equipment utilized. 

The eye testing equipment market is witnessing growth and is projected to reach USD 5,246.1 million by 2030. 

Retinal Camera 

Eye doctors utilize the retinal camera to capture photos of the inside of the eyes, precisely the retina. It functions by beaming a light into your eye and taking high-resolution pictures for detailed images.  

This will aid in detecting any signals of harm or illness. It is rapid, painless, and gives a precise peek at what’s happening inside your eyes for a healthier diagnosis from your optometrist. 


The phoropter controls the suitable lens medicine for their patients. During an eye check, the patient will look at an eye chart while the oculist switches between diverse lenses on the phoropter. 

The oculist will utilize the data collected from the patient, who classifies the lens combination that delivers the clearest vision, to determine the suitable prescription. 


The ophthalmoscope studies the inside of the eye. 

It has a light and a lens that aids the medic see inside your eyes, similar to utilizing a penlight in the dark. Your oculist might use it to spot any signals of harm or illness-distressing vision, like retinal detachment, or eye illnesses, like glaucoma. 

Manual Keratometry 

The manual keratometer calculates the curve of an individual’s cornea. The cornea is situated in the front part of the eye and aids in concentrating the light onto the retina. Its shape affects how light enters the eye and is treated by the retina. In cases where the cornea is otherwise shaped, it can lead to an eye condition called astigmatism. 

To examine for astigmia, the keratometer beams light into the eye and calculates how it reflects off 2 mirrors inside the instrument. 

Slit lamp 

The slit lamp studies the back and front of the eye in detail. It syndicates a microscope and special light that gleams into your eyes, letting the medic see diverse parts such as the retina, cornea, lens, iris, and optic nerve. Your oculist might utilize it to spot problems like scrapes on your cornea, harm to your retina, and circumstances like cataracts or glaucoma. 

Snellen chart 

The Snellen chart calculates visual insight. Visual acuity shows how well one can view at diverse distances and is kept in the form of a fraction. For example, having a 10/20 visual acuity means they can see the chart as evidently at 20 feet away as someone with “normal” vision would see it from 30 feet away. 

The chart consists of rows of letters or symbols that get smaller as you move down the chart. Your eye doctor will ask you to read each row from a distance away and record your results.
