high tech senior 640

We’ve come a long way since 1270, when Marco Polo discovered elderly Chinese people using magnifying glasses to read.

Technology for people with low vision has changed dramatically—even in the last few years! Today, people with low vision have unprecedented access to cutting-edge medical procedures as well as a wide range of low vision devices and aids, including high-tech headsets and mobile phone apps that help them to read, navigate the world around them, and recognize faces.

If you or someone you love is living with low vision, contact Dr. Roderick Fields to discover which low vision devices or low vision glasses will help you live more independently.

Low Vision Electronic Devices

There are a number of low-vision devices and low vision glasses that may help you make the most of your remaining vision.

Macular degeneration causes people to lose central vision when the center of the eye’s retina (the macula) degenerates with age. While macular degeneration is considered incurable, a system using VR goggles and software to magnify the field of vision are sometimes the best way to help those with macular degeneration maximize the use of their remaining vision.

This headset system can help restore the user’s ability to watch TV, read, and do other everyday activities.

Other new assistive technologies include video magnifiers, desktop closed-circuit TV (CCTV) systems, and screen readers. These all allow people to have an up-close view of screens that their vision cannot provide, allowing them to see images and texts more clearly.

Low Vision Apps

Tablets and smartphones now have built-in capabilities for people with low vision, such as:

  • High-definition screens that improve visual clarity
  • Camera lenses that capture and magnify images
  • Speakers that convey directions and words
  • Microprocessors for assistive mobile applications
  • GPS receivers for location-awareness and navigation

Moreover, artificial intelligence can now vocalize written words and sentences so that you understand what you’re seeing—no matter how limited your vision may be.

Low-Vision Assistant Options Keep Growing

There are countless new technologies that can help people live better lives with low vision. However, determining which assistive technologies can best address your needs may feel overwhelming. Southern Low Vision will be happy to help by matching you with the latest and more suitable low vision device so you can live your best life.

How to Avoid Being Blindsided by Glaucoma

Dry Eye Senior Woman 640×350

January is Glaucoma Awareness Month, a timely reminder to get your eyes checked!

At least 3 million Americans have glaucoma, and of them, an astonishing 50% don’t even know they have it! In 95% of cases, glaucoma shows no symptoms in its early stages, and by the time symptoms appear, lost vision cannot be restored.

This is why the most effective way not to be blindsided by glaucoma is to undergo regular annual eye exams — even if you think your vision is perfect. If you are diagnosed with glaucoma, a low vision optometrist can provide you with the vision aids and strategies to help you maximize your vision for a heightened quality of life.

What Is Glaucoma?

Glaucoma is a build up of pressure within the eye that causes damage to the optic nerve. The longer the pressure builds, the more damage it causes. Eventually, the nerve will deteriorate to the point of no return, resulting in permanent vision loss or blindness.

How Is Glaucoma Detected?

Early detection is key with glaucoma. Seeing your eye doctor at least once a year for a comprehensive exam is absolutely necessary to avoid vision loss or blindness. During your exam, your doctor will test your eye pressure, examine your optic nerve, and assess your visual field, among other things.

There are several ways to test for glaucoma.

  • Air Puff Test – The puff of air is used to gently reflect off the front of your eye. The machine then calculates how much resistance your eye had to the air blast. This will let your doctor know the amount of pressure inside your eyes.
  • Tonometer – The pressure in the eye is measured by testing resistance, using a small device that gently touches your eye. Your eyes will be numbed with drops, so you won’t feel this light touch.
  • Blue Light Test (Goldmann tonometry) – Your eye doctor will first place numbing drops into your eyes. Then your doctor will use a device called a slit lamp biomicroscope, which slowly moves a flat-tipped probe until it gently touches your cornea. This method is considered the gold-standard for measuring eye pressure. That said, the other two methods are widely used, as they are both comfortable and accurate.

If glaucoma is detected early enough, it can usually be managed to prevent more acute vision loss or blindness. Once vision loss becomes clearly noticeable, it means that the disease has progressed and has entered its advanced stages. At this point, any vision loss incurred is permanent. Fortunately, a low vision optometrist can help manage the condition so you can live your best life.

A Low Vision Optometrist Can Help Manage Glaucoma

If you or a loved one has been diagnosed with glaucoma, a low vision doctor can help by offering a variety of high and low tech products to help these patients see more clearly. In fact, the vast majority of patients we fit with custom optics or other low vision devices experience a profound improvement in their day to day life. If you’ve experienced vision loss, the sooner you begin to use low vision aids, the quicker you will adjust and learn new ways of retaining your “normal” lifestyle and activities.

While we help manage the condition, it’s critical to have it diagnosed early on for optimal results. And the only way not to be caught blindsided is to receive an early diagnosis through your annual comprehensive eye exam. Protect your sight and schedule your annual eye exam with Southern Low Vision today.

What Causes Low Vision And Blindness In Children?

Low Vision And Blindness In Children 640×350Every year, more than half a million children suffer from low vision or blindness in North America. Having impaired vision makes it difficult to read, play sports, participate in social events, and recognize faces. Low vision can also make it difficult to navigate outdoors, especially on crowded sidewalks and busy streets.

Often, the first signs of low vision can manifest as a child appearing clumsy or inattentive, when the true problem lies in their vision.

We understand how impaired vision can adversely impact a child’s life, and we’re here to help. Our low vision doctors offer a variety of helpful strategies vision aids that can help maximize your child’s remaining vision, thus ensuring the highest quality of life under the circumstances.

Read on to learn about some common causes of low vision and blindness in children and discover how a low vision optometrist can help children with impaired vision live their best lives.

Leading Causes of Pediatric Low Vision and Blindness

Albinism

Albinism is an inherited condition that affects melanin production. Melanin is the pigment in the skin, hair, and eyes that gives each person their own unique coloring. Some people with albinism have very little melanin, while others have no melanin at all.

Aside from making a person look different on the outside, albinism can also affect how the eyes function. Healthy amounts of melanin are used in the development of the retina (light sensitive lining at the back of the eye). Reduced amounts of melanin in the eyes, or none at all, can cause a range of vision problems including:

  • Poor eyesight — nearsightedness or farsightedness
  • Low vision — irreversible vision loss
  • Astigmatism — where the clear part at the front of the eye (cornea) isn’t curved correctly or the lens is abnormally shaped, causing blurred vision
  • Photophobia — light sensitivity
  • Nystagmus — involuntary, rapid eye movements
  • Squint — eyes pointing in different directions

Vision problems associated with albinism last a lifetime, but typically don’t worsen over time.

Pediatric Cataracts

A cataract is the opacity or cloudiness that occurs in the eye’s lens, which is crystal clear in a healthy eye. Some cataracts are small and won’t interfere with vision, while others are large and can cause severe vision loss.

An estimated 3 out of 10,000 children have cataracts. Common causes of pediatric cataracts are genetics, infections, and abnormal lens development in utero. Not all cataracts interfere with vision, as some are small or on the outer edges of the lens. If a cataract interferes with the child’s vision, it should be surgically removed as soon as safely possible.

Pediatric Glaucoma

Pediatric glaucoma (also referred to as childhood or infantile glaucoma) is generally diagnosed before a child’s first birthday. Glaucoma causes an increase in the eye’s internal pressure, which can lead to permanent optic nerve damage. Aside from vision loss, symptoms of pediatric glaucoma include enlarged eyes, photosensitivity (light-sensitivity), excessive tearing, and cloudiness in the cornea. In many cases, childhood glaucoma can be effectively managed and treated.

Retinal Diseases

Certain retinal diseases, like Stargardt macular dystrophy, retinitis pigmentosa (RP), Usher syndrome, Leber congenital amaurosis, and Bardet-Biedl syndrome can cause low vision or blindness in children. Children with these retinal diseases should be closely monitored by a low vision optometrist as the condition progresses.

Ocular Trauma

Ocular trauma is a leading cause of acquired monocular blindness (blindness affecting one eye) among children. According to a study published in The Journal of Ophthalmology, about a quarter of a million children are treated for serious ocular trauma yearly in the USA alone. Up to 14% of those cases resulted in visual impairment or blindness. Whenever possible, ensure that your child is wearing protective eyewear when doing certain crafts, playing sports, or engaging in any activity that could pose a risk to their eyes.

How a Low Vision Optometrist Can Help

Many children with vision loss can live full and independent lives. While we may not be able to restore lost vision, we do offer several low vision aids and devices that can help maximize a child’s usable vision. This will enable the child to make the most of their sight, continue to function as independently as possible, and not miss out on the joys of being a kid.

If you have a child with low vision, contact Southern Low Vision today. We can help.

Why Do Colors Appear Less Vibrant?

colors 640You’re deciding which clothes to wear, but wonder why their bright colors suddenly seem subdued. Or perhaps they look faded with your right eye but not your left eye.

Odd, right?

Not seeing colors the way you used to is often a symptom of optical problems, especially as we age. Let’s take a look at some of these diseases and explore ways a low vision eye doctor can help you improve or at least maximize your vision.

Cataracts occur when protein deposits accumulate on the eye’s crystalline lens and turn it opaque. Once-clear vision becomes cloudy and colors begin to fade.

The good news is that cataract surgery is a very safe procedure that replaces your cloudy lens with a new, clear lens. If you’ve had cataract surgery to restore clear vision, you’ll notice right away that colors appear much brighter than before. A few years after cataract surgery, some patients notice that colors may start to appear subdued. This is normal and can be treated very quickly using a laser procedure.

Glaucoma results from high pressure build-up inside the eye, which damages the optic nerve, reduces vision and can lead to blindness. Color-vision deficiency — the inability to tell certain colors apart — can be one of the signs that glaucoma is starting to affect the eyes.

The difficulty in distinguishing between blue and yellow colours is often associated with early glaucoma, whereas red-green deficiencies are generally associated with advanced glaucoma. However, there are times when it is difficult to measure or quantify acquired color vision deficiency, and color tests performed with standardized color test charts frequently characterize it as combined or nonspecific color vision deficiency.

Macular degeneration primarily affects older people by causing a deterioration of the macula, the center of the retina. This leads to blurriness and significant vision loss. Experiencing difficulty distinguishing between similar colors and hues is an early sign of the condition.

Optic neuritis occurs when the body’s immune system attacks the myelin coating on nerve fibers, causing blurriness and partial vision loss in one or both eyes. Colors, especially shades of red, become subdued, and it becomes harder to distinguish against a similarly colored background. Fortunately, the condition is usually temporary.

Diabetic retinopathy affects people with diabetes when high blood-sugar levels damage blood vessels in the retina. This causes these tiny blood vessels to swell, leak fluid, or close, and can even cause abnormal new blood vessels to grow. These new vessels are very fragile and prone to being damaged. Symptoms often include fading colors, blurriness, vision loss, and more.

What to Do When Color-Related Difficulties and Other Visual Symptoms Arise

If you notice that your color vision is reduced, you may be in the early stages of a range of eye diseases. It is important for any eye condition to be diagnosed and treated early on so it can be effectively treated.

If these eye diseases are not managed early, the color-related problems you’re experiencing could worsen, eventually affecting your vision permanently, resulting in what is known as low vision. Low vision indicates that your vision has deteriorated to a point which makes your everyday tasks challenging and can negatively impact your quality of life.

If you notice that colors are diminished or you are experiencing other worrying symptoms affecting your vision, immediately consult Dr. Roderick Fields. We will examine you by:

  • Dilating your pupils
  • Evaluating your visual acuity
  • Providing a visual field examination
  • Providing a colour vision assessment
  • Conducting eye pressure tests

The sooner we identify the underlying cause behind your reduced color vision, the sooner you will be able to start treatment to improve or maximize your vision.

Reading Tips For Those With Macular Degeneration

Woman 1.7FD w Cap.KinkadeThe most serious symptom of macular degeneration (AMD) is the loss of central vision, with those in the more advanced stages of AMD experiencing a smudge or black spot in the center of their vision. This makes it difficult to read and causes many people to give up on reading.

It doesn’t have to be this way.

Below you will find a list of low vision devices and strategies that can help people with AMD read more easily and comfortably.

Members of The International Academy of Low Vision Specialists are experts in determining which low vision devices will work best for you for reading.

Low Vision Devices for Reading

Reading Magnifier

Hand-held magnifiers are the most commonly used visual aids for spot reading among those with AMD and other low vision conditions. In the correct power, they are useful for reading medicine bottles, prices, labels, oven dials, etc. While you can find small pocket magnifiers, full-page illuminated magnifiers, and magnifiers that are mounted on adjustable stands, only your low vision doctor can determine exactly what power you need.

Portable Electronic Magnifiers

A portable electronic magnifier resembles an iPad or a tablet. By holding this device in front of your reading material, you can view the magnified version on its LED screen.

High-Power Reading Glasses

Strong magnifying reading eyeglasses enable a person with severe visual impairment to read the fine print. Your low vision eye doctor will determine the correct near prescription and demonstrate how they work.

Video Magnifier

Although traditional optical magnifiers, such as magnifying glasses, are generally very helpful, some people benefit more from a video magnifier. A video magnifier, or closed-circuit television (CCTV), has a camera that transmits magnified images (up to 50x or higher) and displays them on a large monitor or TV screen. You can sit as close to the screen as you like and adjust the magnification, brightness, and contrast for reading clarity.

Tele-Microscopic Glasses

Tele-microscopic lenses are mounted on the eyeglass lenses and may be prescribed for one or both eyes. They allow people with low vision to read, use a computer, write, and perform other tasks at a comfortable distance.

Certain low vision devices require a prescription from an eye doctor as they are custom-made for your specific needs. Consult Dr. Roderick Fields, who will help determine which vision aids are best for your needs, based on your lifestyle and level of vision impairment.

Other Strategies To Help You Read With Macular Degeneration

Increase in Contrast

It’s important to ensure a stark contrast between the text being read and its background. Newspapers don’t offer much contrast because the grey letters sit on an off-white background.

Many electronic screens allow you to tailor the contrast to your needs: black lettering on a white background; white lettering on a black background; black lettering on a yellow background; and yellow lettering on a dark black background. Try the different color combinations and settle on the color contrast combination that offers the best contrast for the most comfortable reading experience.

Increase Lighting

Increasing the amount and type of lighting can greatly improve reading ability in those with AMD.

Direct light. A standard table lamp usually won’t provide sufficient light for reading a book. Consider getting an adjustable gooseneck lamp that allows you to focus the light directly onto the reading material.

Sunlight. Because natural sunlight is the ideal lighting for reading, try to arrange your furniture in such a way that you can sit near a window for comfortable daytime reading.

Lightbulbs. Use the brightest light bulbs for each light fixture in the house. These include LED, halogen, and full-spectrum light bulbs (which mimics natural sunlight more than incandescent bulbs). Be careful with halogen, however, as they may create excessive heat. Replace any fluorescent lighting in the house, as it can cause glare, particularly for those with low vision. For reading, however, the best option is to use lower strength light bulbs and bring the lamp closer.

E-reader. Kindles and other e-readers conveniently include a built-in light that allows you to adjust brightness for more comfortable reading.

Large Print Books or Larger Fonts

Consider purchasing large print books online or in book shops, as they include larger fonts, more spacing and better contrast. If you opt for electronic books, you can conveniently increase the font size, rendering it easier and more enjoyable to read.

Adjust Spacing

Your electronic reading device allows you to adjust the spacing between the lines as needed. By widening the space between lines, you will find reading easier and will experience less eye strain.

Speak with Dr. Roderick Fields for more advice on reading with macular degeneration or to get low vision aids and devices.
