Our Technology

e2e Vision performs eye exams utilizing state-of-the-art technologies to assess your vision and ability to focus on and discern objects. We are proud of the high level of technology we bring to East Texas.

Sirius Visual Acuity System

Sirius Visual Acuity System

Computer-based eye chart system allows us to randomize our tests to prevent memorization. It has the ability to play video clips and various digital images as fixation targets for children. Unlike projected eye chart, the Sirius Visual Acuity System maintains constant eye chart clarity to help efficiently improve acuity testing accuracy.


Huvitz Digital Refractor HDR-7000

Huvitz Digital Refractor HDR-7000

The Huvitz Digital Refractor allows your prescription refining process to be seamless with simultaneous images presented next to each other for comparison rather than the alternating, flipping back and forth of choices. You are more likely to end up with a better prescription by not having to second guess yourself.


OCULUS Keratograph 5M

OCULUS Keratograph 5M

This high tech instrument measures the curvature of the front surface of the eye called the cornea. It allows us to detect and monitor corneal diseases such as Keratoconus. It also has the ability to capture an infrared imaging of the oil glands along the eye lids called Meibomian glands that can cause the majority of dry eyes; this allows us to tailor our dry eyes treatment based on the cause of dry eyes.


Topcon Maestro 2

Topcon Maestro 2

The Maestro II allows us to capture a digital imaging of the different layers of the retina to detect diseases such as Macular Degeneration, Glaucoma, Diabetic Retinopathy, etc. This technology allows us to diagnose and monitor most retinal conditions.


Marco Equinox LLLT

Marco Equinox LLLT

The Equinox is a new and advanced instrument that uses Red Light Wavelength that has been dialed in to penetrate underneath the skin surface to deliver precise wavelength energy to the oil glands along the eye lids to help alleviate evaporative dry eyes.



Optos California.

The Optos California is an ultra-wide digital imaging system that captures 220 degrees of the retina for screening purposes. It allows us to screen for retinal issues such as retinal tear, retinal detachment, etc.
