Vision Diagnostic Equipment

At Copeland Eye Care, we provide comprehensive eye care. Our office is equipped with the latest diagnostic technology. Our experienced team uses a combination of a slit lamp, Optical coherence tomography (OCT), and OptoMap additional specialized optometric diagnostic devices that help our optometrists provide our patients with the most comprehensive testing available to best evaluate eye health.

Slit Lamp

A slit lamp is a medical instrument used to examine the front part of the eye, including the cornea, iris, lens, and anterior chamber. It is a type of biomicroscope that uses a high-intensity light to illuminate the eye and a microscope to magnify the image. Slit lamps are used by eye doctors to diagnose and treat a variety of eye conditions, including:

  • Conjunctivitis (pink eye)
  • Dry eye
  • Glaucoma
  • Cataracts
  • Uveitis
  • Corneal abrasions
  • Contact Lenses

Slit lamps are also used to perform a variety of procedures, such as:

  • Dilating the pupils
  • Removing foreign bodies from the eye
  • Taking photographs of the eye
  • Applying medications to the eye

If you are experiencing any eye problems, it is important to see an eye doctor for a diagnosis and treatment. Your eye doctor may use a slit lamp to examine your eyes and determine the cause of your symptoms.


Optical coherence tomography (OCT) is a non-invasive imaging procedure that uses light to create detailed cross-sectional images of the retina. It is a valuable tool for diagnosing and monitoring a variety of eye conditions, including macular degeneration, diabetic retinopathy, and glaucoma.

The OCT device emits a beam of light into the eye and measures the way the light bounces back. This information is used to create a detailed image of the retina. OCT can also be used to monitor the progression of an eye condition over time. This information can be used to determine the best course of treatment for each patient.


An Optomap is a revolutionary system that takes a 3D image of the back of your eye. It is used to detect early signs of eye diseases such as glaucoma, macular degeneration, hypertension and diabetic retinopathy.

An Optomap differs from a traditional camera because it allows your doctor to see a larger area of your retina. This can help your doctor detect problems that may not be visible with a traditional camera system.

For some people an Optomap is also more comfortable than a dilation because it does not require you to hold your eyes open with drops, wait for them to work and then be blurred and light sensitive for 3-4 hours.

Meibomian gland imaging

Meibomian gland imaging is a non-invasive procedure that uses infrared light to create images of the meibomian glands, which are located on the inner surface of the eyelids. The images can be used to diagnose and monitor meibomian gland dysfunction (MGD), a common condition that can cause dry eye.

MGD occurs when the meibomian glands become blocked and inflamed. This can lead to a number of symptoms, including dry eyes, blurred vision, and eye fatigue. In some cases, MGD can also lead to more serious problems, such as corneal ulcers and vision loss.

Meibomian gland imaging can help to identify the cause of MGD and to monitor the effectiveness of treatment. It is painless and takes only a few minutes to complete.

Fundus Camera

Eye fundus imaging is a non-invasive procedure that uses a special camera to take pictures of the inside of your eye, including the retina, optic nerve, and blood vessels. The images can be used to diagnose and monitor a variety of eye conditions, such as glaucoma, age-related macular degeneration, and diabetic retinopathy.

Eye fundus imaging is a painless procedure that takes only a few minutes to complete. Your eye doctor may or may-not dilate your pupils with eye drops to allow for a better view of the inside of your eye. Then, they will use a special camera to take pictures of the back of your eye. You may need to hold your head still during the procedure.

Digital Phoropter

A digital phoropter is a device used by eye doctors to measure the refractive error of the eye. It is a computerized version of the traditional phoropter, which uses lenses and prisms to measure the eye’s power.

A digital phoropter has several advantages over a traditional phoropter. It is more accurate, as it can measure the eye’s power to within 0.01 diopter. It is also faster, as it can measure the eye’s power in seconds. Additionally, a digital phoropter is more comfortable for the patient, as it does not require the patient to hold their eyes open for as long. We can easily compare previous results with current results to quickly identify any changes.

Visual Field Testing

A visual field machine is a device that measures the range of vision. It is used to diagnose and monitor eye conditions such as glaucoma, optic nerve disorders, and brain tumors.

The visual field machine is a large, computerized device with a screen and a button. The patient sits in front of the screen and looks at a small dot in the center. The machine then projects a series of lights at different points in the patient’s peripheral vision. The patient presses the button when they see the lights.

The machine records the patient’s responses and creates a map of their visual field. This map can be used to identify areas of lost vision. Visual field testing is a painless and quick procedure.

Visual Acuity

A digital acuity chart is an electronic version of the traditional Snellen eye chart. It is used to measure visual acuity, which is the ability to see fine detail.

A digital acuity chart typically consists of a series of letters or numbers that are displayed on a screen. The letters or numbers become smaller as they progress down the chart. The patient is asked to read the letters or numbers from top to bottom.

The smallest line of letters or numbers that the patient can read correctly is their visual acuity. Visual acuity is measured in terms of diopters. A diopter is a unit of measurement that indicates the power of a lens.

A digital acuity chart is a quick and easy way to measure visual acuity. It is also a more accurate way to measure visual acuity than a traditional Snellen eye chart.


This machine provides eye-tracking technology to help people improve their vision and performance. The company’s technology is used by a variety of people, including athletes, students, and people with disabilities.

RightEye’s technology works by tracking the movement of the eyes. This technology has been shown to be effective in improving vision and performance. A study published in the journal Optometry and Vision Science found that RightEye’s technology was effective in improving reading speed and accuracy in children. Another study published in the journal BMC Sports Science, Medicine and Rehabilitation found that RightEye’s technology was effective in improving basketball shooting accuracy in college athletes.
