A loss of the nerve fibers in the optic nerve is called optic nerve atrophy. Degeneration or damage of the optic nerve causes images to not be carried to the brain, causing sight to be blurred. The effects range from visual change to severe visual loss. In the center of the retina lays the optic nerve, carrying over one million nerves connected to the retina. This layer of the eye carries the vision cells that part of the brain depicts as vision.
What Causes Optic Nerve Atrophy?
The most common cause of optic nerve atrophy is poor blood flow, called ischemic optic neuropathy. Also, the nerve can be damaged by trauma, radiation, trauma, and shock.
The following conditions can lead to optic nerve atrophy:
- Brain tumor
- Multiple sclerosis
- Cranial arteritis
In some rare cases, optic nerve atrophy can be cause by a hereditary condition or a congenital problem.
What are the Symptoms?
The field of vision is reduced and the capability of seeing fine detail is lost. The main symptoms are:
- Blurred vision
- Abnormal side vision
- Abnormal color vision
- Decreased brightness and sharpness in vision
How is it Diagnosed?
An eye exam is necessary to figure out the cause of optic nerve atrophy. An ophthalmologist uses an ophthalmoscope to look at the optic disc, the back of the eye where the optic nerve enters. The optic disc will appear pale in optic atrophy due to change in blood flow of the vessels. Further tests may be necessary, including a magnetic resonance imaging (MRI) or blood tests.
How is it Treated?
There is no cure or effective treatments for Optic Nerve Atrophy. Regular eye exams are important because an early diagnoses and treatment of the underlying cause can prevent further risk of development. Once the nerve fibers are lost they never grow back.
How does it Affect Daily Life?
Blurriness often affects those with optic nerve atrophy, which is not possible to correct with normal glasses. There is a loss of the peripheral field and central field. In addition, it is possible to have a sensitivity to bright light and glare.
This can lead to difficulties in:
- Recognizing faces and facial features
- Seeing things close and in detail
- Gathering comprehensive visual information
- Writing, reading, and using a computer
- Gathering an orientation of the surroundings
How does NuEyes Help Optic Nerve Atrophy?
With a lack of vision and no cure for Optic Nerve Atrophy, people wonder what options they have for sight. The answer is available in the form of NuEyes ODG smartglasses.
1. What can you see?
Optic Nerve atrophy can cause difficulties in writing and reading. NuEyes ODG Smartglasses can help by making text larger or smaller with voice-command. A feature of auto-focus helps in seeing things in fine detail or faraway. NuEyes Smartglasses makes it easy to gather an orientation of your surroundings. The world is brought closer to you by images being projected on the inside of the glasses lenses.
- Makes text larger or smaller with voice-command
- Auto-focus allows seeing in fine detail or faraway
- Easier to gather an orientation of surroundings
- Images are projected on the inside of the lenses
2. What freedom do they Allow?
A hands-free device allows use of both hands while the low vision glasses enable vision. The head-worn display for low vision is voice activated, has an adjustable HD camera, wireless battery powered, and is able to browse the web, emails, and social media. Michael A. Samuel, a retina specialist, says, “A device like this allows them to take this technology outside of the home to places they want to go. It expands their ability to live their life a little bit more than they did before.” This wearable technology is the future for patients with low vision, allowing them the ability to see in stores, restaurants, and anywhere they wish to go.

3. What are the Details?
An HD digital camera mounted on the center bridge of the frames streams images to built-in 3D stereoscopic HD display lenses. An LED light helps to see in dark environments. A touch interface on the temples of the smartglasses provides haptic feedback, a vibration when touched to alert that it’s been pressed. The NuEyes ODG smartglasses are auto focus with high definition optics, other features include Bluetooth, Wi-Fi, and a GPS sensor. Magnification is available up to 12x, allowing sight of people or objects in close detail. A sensor within the NuEyes ODG smartglasses reads the barometric pressure and humidity in the users environment.
