This instrument is a wonderful addition to our office. Similar to an ultrasound, this non-contact imaging device allows us to view cross-sections and three-dimensional images of several structures of the eye. The OCT is a diagnostic device used to aid in the detection and management of ocular diseases, such as glaucoma, macular degeneration, and diabetic retinopathy, among others.

Auto Refractometer

In old fashioned eye exams, the doctor spent quite a bit of time getting the right amount of vision correction, known as refraction, for each person's vision.  An auto refractometer is a machine that helps the doctor speed up this process by calculating the proper refraction so that the doctor only needs to slightly adjust the prescription to meet the needs of the patient.  It shines a cone of infrared light into the eye and uses sensors to detect the reflections of that light.  The reflections give information to the sensors about where the eye is focused properly.   While an auto refractometer does not look at the complete clinical picture for each patient, this saves the doctor a great deal of time.  This makes for a faster, more accurate, and more convenient eye exam, and gives the doctor time to be more thorough and attentive to the individual needs of the patient.    An auto refractometer is used for eye exams at the Arvada Optometric Center.

Annual eye exams are vital to maintaining your vision and overall health. Arvada Optometric Center offers the optomap® as an important part of our eye exams. The optomap produces an image that is unique and provides Dr. Cottrell with a high-resolution 200° image in order to ascertain the health of your retina. This is much wider than a traditional 45° image. Many eye problems can develop without you knowing, in fact, you may not even notice any change in your sight – fortunately, diseases or damage such as macular degeneration, glaucoma, retinal tears or detachments, and other health problems such as diabetes and high blood pressure can be seen with a thorough exam of the retina.


The inclusion of optomap as part of a comprehensive eye exam provides:

  • A scan to show a healthy eye or detect disease.
  • A view of the retina, giving your doctor a more comprehensive view than they can get by other means. The opportunity for you to view and discuss the optomap image of your eye with your doctor at the time of your exam.
  • A permanent record for your file, which allows Dr. Cottrell to view your images each year to look for changes.

The optomap is fast, easy, and comfortable for anyone. The entire image process consists of you looking into the device one eye at a time. 

Optical Lens Edging Machine

Optical Lens Edging Machine Lenses for eyeglasses are complex feats of engineering. Custom made for each individual, glasses are designed so that the frames fit the face and the lenses line up with the gaze of the wearer to make the most of the power of the optics of the lens. While the optician makes this as easy as possible for each client by making measurements so that the center point of the lens is calculated correctly, specialized lens cutting equipment in house can allow the optician to make lenses so that the process is quick and convenient. The optical lens edging machine is one such piece of equipment. It cuts and bevels the edge of the lens so that they fit properly into the frames. This precision equipment saves the optician a lot of time and leaves only tiny adjustments to be made with hand equipment when necessary. Arvada Optometric Center uses an optical lens edging machine in their optical laboratory.
