Reporting on the latest innovations impacting seniors

Electronic glasses help visually impaired seniors see

  

Vision loss is devastating. But what if there were a way to restore you or your loved one's eyesight? The company eSight has spent years working with leading eye doctors from all over the world to develop this vision-restoring technology. eSight's glasses use a high-definition camera to capture your surroundings and display it on two near-to-eye displays. These functions allow you to move easily with high-speed access to peripheral vision! eSight's innovative invention allows visually impaired individuals to enjoy the things they love again, Whether it's watching television, painting, reading the newspaper, or even hiking! 


eSight's features: 

- 24x zoom. 

- Increased central field of view. 

- Autofocuses on short, medium, and long-range objects. 

- Image contrast enhancement. 

- Bioptic TIlt capability. eSight's user 

- eSight has a processing unit. The user will carry a light-weight processing unit which adjusts each pixel of the video. 

- Streaming. This amazing feature allows you to stream videos and other content directly to the screens in front of your eyes.

- eSight features prescription lenses specific to your needs. 

-The front camera captures your surroundings in ultra HD.

- HDMI and USB inputs. 

- The glasses are dust and water resistant. 

- Bluetooth. 

- Wifi.

- Removable SD cards. 

- Hands-free! eSight is the only assistive technology for the visually impaired that is mobile. 

eSight is capable of giving blind people their independence back! For some, wearing the glasses can give the equivalent of 20/20 vision. eSight's 24x zoom feature also allows you to see further and often with more clarity than those with their eyesight. 


An unfortunate aspect is the cost of eSight, being $10,000. Nonetheless, the generosity of Jeff Fenton, eSight's director of outreach, and other donors contribute to making blindness a thing of the past. While eSight is costly, it has no competitors, as it is the best alternative to white canes, eye dogs, CCTV, and even surgical methods. 

How can you or a loved one qualify? 

Legal blindness is defined as visual acuity of 20/200 or worse. There are also several causes of blindness. 

-Cataract, 9.8% 

-Glaucoma, 11.5% 

-Optic nerve atrophy, 4.3%

-Macular degeneration, 16.8% 

-Unknown/other, 47.5% 

However, macular degeneration is the most common among eSight users. 

Macular degeneration is an incurable sight condition which typically occurs when the central portion of the retina deteriorates. This condition is considered to be more serious than glaucoma and cataracts.  Regular visits to the eye doctor are important even before the symptoms appear. These symptoms being: 

- Blurry, shaded areas (or whiteout) appear in the center of your visual field.

- In some cases, individuals experience a change in their perception of color. Their color vision becomes noticeably paler over time.

- Straight lines appear as wavy. For example, sentences on a page or the edge of a table. 

- Objects will appear to be smaller than they actually are. 

- Over time, it becomes more difficult to see textures and slight contrast. 

- Changing light levels can be a big issue. Having difficulty with your eyes adjusting to sunlight is a common symptom of macular degeneration. 

- Once you start losing your depth perception, walking becomes more difficult. Without depth perception, your ability to accurately judge distances is diminished.

While age-related macular degeneration is the most common, there are many other possible causes, including: 

-Smoking cigarettes. 

-Lighter eye color. 

-Drug side effects. 

-Heredity. 

-Obesity or inactivity. 

-High Blood Pressure. 

Blindness can affect anyone, regardless of age. Among the estimated 40 million blind persons, the age range is as follows: 

-4% are age 14 or younger 

-8% are 15-44

-34% are 45-59

-58% are 60+ 

While eSight works for a variety of conditions, it is most effective for individuals with an acuity ranging from 20:60 to 20:400. Below are some of the conditions eSight works for: 

-Diabetic retinotherapy. 

-Nystagmus.

-Glaucoma. 

-Ocular Albinism. 

-Cone-rod dystrophy. 

-Optic Nerve Hypoplasia

-Optic atrophy. 

-Stargardt’s Disease.

-Macular degeneration.

 


Senior Visual Impairment

 

Vision loss is a major healthcare problem, especially among elderly individuals. Approximately one out of three people have some form of vision-reducing eye disease by the time they are 65. However, the most common causes of vision loss for elderly individuals are glaucoma, cataract, age-related macular degeneration, and diabetic retinopathy. Below are the causes and symptoms of each disease:

However, the most common causes of vision loss for elderly individuals are glaucoma, cataract, age-related macular degeneration, and diabetic retinopathy. Below are the causes and symptoms of each disease: 

Age-related macular degeneration: 

Age-related macular degeneration (also known as AMD) is one of the leading causes of blindness in individuals over 65 years of age. AMD is distinguished by degeneration of the macula, which is the area of the retina responsible for central vision. Some of the risk factors for AMD include cigarette smoking, advancing in age, family history of AMD, and cardiovascular risk factors such as hypertension. 

There are two distinguishable types of age-related macular degeneration: exudative (or "wet) AMD and nonexudative (or "dry"). 90 percent of individuals with age-related macular degeneration have the nonexudative form of the disease, while a smaller percentage has exudative AMD.  Drusen are localized deposits of extracellular material that are collected in the macula. These yellowish-white deposits are typically symmetric in distribution and number, occurring in both eyes.

However, approximately 10 percent of individuals with AMD develop the exudative form of the disease. This type of AMD is characterized by the growth of abnormal vessels from the choroidal circulation to the subretinal space. Said abnormal vessels leak blood and fluid in the macula, resulting in distorted or blurred central vision. Eventually, fibrosis will develop, leaving a macular scar. 

Glaucoma:

Glaucoma encompasses a group of eye conditions that damage the optic nerve. The damage is typically caused by unusually high pressure in your eye. Unfortunately, the most common form of glaucoma shows no warning signs. Its effect is so gradual you might not notice a difference in your vision until the condition is at an advanced state. Vision loss due to glaucoma can't be recovered and can occur at any age. It's important to have frequent eye exams of which include measurement of your eye pressure. If glaucoma is detected early on, vision loss can be slowed or even prevented. There are some symptoms you can look out for: 

Acute angle-closure glaucoma

-Eye redness. 

-Blurred vision. 

-Severe headaches or migraines. 

-Halos around lights. 

-Nausea and vomiting. 

Open-angle glaucoma

-Tunnel vision occurs in advanced stages.

-Patchy blind spots in your peripheral or central vision. This typically occurs in both eyes. 

If glaucoma is left untreated, the disease will eventually cause blindness. Even with treatment, only around 15 percent of individuals with glaucoma become blind in at least one eye within 20 years. 

Open-angle glaucoma is the most common form of the eye disease. The drainage angle created by the cornea and iris remains open, but the trabecular meshwork is left partly blocked. This causes pressure in the eye to gradually increase over time, damaging the optic nerve. Sadly, it happens so deliberately that you might lose your vision before you are even aware of a problem. 

Angle-closure glaucoma, also known as closed-angle glaucoma, occurs when the iris bulges forward to block the drainage angle formed by the iris and cornea. This means the fluid can't circulate through the eye and pressure increases. While you may not be able to prevent glaucoma, there are steps you can take to detect the disease early, limit vision loss or slow its process.
