Photosensitive Epilepsy

Photosensitive epilepsy was first documented in 1885 in individuals affected when exposed to bright light.  Since that time 10 percent of newly diagnosed cases of seven to nineteen year olds have seizures triggered by TV or computer games.

The triggers vary from person to person, but some of the most common triggers are:

  • Flashing light

  • Bright, contrasting patterns such as white bars against a black background

  • Flashing white light followed by darkness

  • Stimulating images that take up your complete field of vision, such as being very close to a TV screen

  • Certain colors, such as red and blue


The seizures may be controlled with medication but several studies have documented success with cross polarized cobalt blue lenses in preventing the seizures.

The original lenses were manufactured by Zeiss and given the name Z1.  The Zeiss Z1 lens is a bright cobalt blue color and filters the longer red wavelengths that are thought to provoke seizures in those afflicted with the photosensitivity. Cross polarization is created by placing the right lens at 90 degrees and the left at 180 degrees.

If you or a loved one suffers from photosensitive epilepsy and would like to learn more about ways to prevent seizures from occurring, please give us a call to set an appointment to discuss your options.

Those Annoying Dark Circles

Are you constantly tired? Or do you just constantly look like you’re tired? If you always have those pesky dark bags hanging out underneath your eyes, don’t worry, you’re not alone.

The main cause of periorbital dark circles is because the skin under your eyes is thinner than anywhere else on your body and shows the blood vessels and the blood they contain.

As we get older our skin loses its elasticity and ability to regenerate, which makes periorbital dark circles more visible. This is why dark circles are more visible in the elderly.

The reason people think you must be tired when you have darker than normal bags under your eyes is because when the body is tired it produces extra Cortisol to keep you awake. Cortisol increases the amount of blood flowing in your body and causes your veins to expand in order to contain it. That includes the blood vessels under your eyes.

If you’re thinking “I’m young, and get plenty of sleep and I still have very dark circles under my eyes” you could be one of the many people who are just genetically predisposed to dark periorbital circles.

Here are a few ways to improve the look of your dark eye circles:

  • Eat less salt

  • Manage your allergies

  • Use a Neti Pot

  • Sleep on your back

  • Wash your face before bed

  • Refrain from consuming alcohol

  • Wear sunblock

  • Don’t smoke

  • Use a cold compress on your eyes

  • Use over the counter eye creams

Arcus Senilis

Often patients have noticed that their dark brown eyes are changing to blue at the edge. This is not actually the eye changing color, but a condition called arcus. The color of the eye comes from the pigment in the iris. This blue color is actually white cholesterol depositing in the cornea that looks blue when superimposed in front of the brown iris.

While this is very common in elderly patients, if seen in a younger patient, it should be a sign to have your cholesterol level checked. The cholesterol deposition in the cornea does not hamper vision because it is in the peripheral cornea rather than the central cornea, but it indicates cholesterol may be depositing elsewhere in the body, where it can have detrimental effects on health.

There are no other symptoms of this condition other than the ring that forms around the corneal periphery. This condition is painless and presents no further health risks for people over the age of 70. If this occurs in people under they age of 40, they could have other medical issues such as hypercholesterolemia, which is high levels of cholesterol in the blood.

If you or a loved one are experiencing this, you should consult your eye care professional and go in to get checked out.

Spring Is Here!

It’s that time of the year. The sun is out. The bees are buzzing (sort of http://sos-bees.org/). Lawnmowers are coming out of hibernation. The boots are being put in the back of the closet to make room for flip-flops and sneakers.

Spring has finally sprung.

It sounds great. Unless you’re one of the millions of people who suffer from seasonal allergies, then it can be a real pain in the eye.

Luckily, there are steps you can take to make sure you are fully prepared to get outside, enjoy the sunshine and smell the flowers.

The first step to managing your allergies is understanding what is causing them. The change in the seasons causes all sorts of allergy-inducing things to be floating around the air. The most common cause of seasonal allergies is pollen from grasses, weeds and trees.

The most common eye allergy symptoms are:

  • Red, irritated eyes

  • Itchiness

  • Tearing or runny eyes

  • Swollen eyelids

  • Soreness, burning, or pain

  • Sensitivity to light


If you suffer from any of these symptoms, don’t worry; there are very easy ways to relieve them. Many over-the-counter types of anti-histamine will help relieve your symptoms almost immediately. These medications work to block the histamines that are causing your discomfort. A number of different kinds of eye drops will give you instant relief as well.

Other ways to reduce the discomfort of seasonal allergies without the use of medications are:

  • Wear sunglasses when you go outside. They'll block some of the pollen and other outdoor allergens from getting into your eyes.

  • Rinse your eyes with water or apply a cold, wet washcloth.

  • Take out your contact lenses.

  • Don’t rub your eyes, no matter how much they itch. It will only make the irritation worse


Don’t bee afraid of allergy season, start enjoying the weather!

Rods and Cones

Today we are going to be talking about Rods and Cones. No, not the ones you use for fishing and traffic detours. We are talking about the photoreceptors in your retina!

Rods are responsible for vision in low light. They are able to track motion and make out shapes, but they do not help with seeing color. There are approximately 120 million rods in the human eye!

The Rods are very sensitive to light, that’s why it is difficult to keep your eyes open when you turn on a light after being in the dark. Think about that next time you’re a room without the lights on!

Cones are responsible for seeing color and perform best in very high light situations.

There are three different types of cones:

  • Short-wavelength sensitive cones

  • Middle-wavelength sensitive cones

  • Long-wavelength sensitive cones


The various types of cones are responsible for seeing different types of colors. The cones are also used to detect detail in objects. Like how the “b” in the previous sentence is just a tad bigger than the rest of the letters on this page!

Now you know, rods and cones aren’t just for fishing and traffic detours!

Why do onions make you cry?

We have all been there. Just hanging out in the kitchen while Mom’s cooking dinner and out of nowhere there are tears running down your face. Are you sad? No. Are you laughing too hard? Probably not. At the peak of your confusion you happen to look to your left and see Mom over there cutting up an onion and suddenly it all makes sense.

But then you think, “Why the heck is this thing making me cry?” Well, you’re about to find out.

Onioncrying-onions are part of the Allium species of plants, which have a tendency to absorb sulfur from the soil. When an onion is cut into, enzymes are released and they react with the sulfur to create amino acid sulfoxides.

The chemical reaction creates syn-propanethial-S-oxide, which is a combination of sulfuric acid, sulfur dioxide, and hydrogen sulfide. When the gasses from this substance come in contact with the fluid in your eye they cause the burning sensation that you feel when hanging out around freshly cut onions.

The burning sensation then causes the eye to naturally produce tears in order to relieve the discomfort that your eye is feeling.

So, next time you’re around some freshly cut onions, be sure to tell everyone what is actually going on.

How The Eye Works

The human eye is an incredible thing. Take a second to think about how cool your eyes actually are. They can see things that are right in front of you or miles away and they can switch between the two almost instantly.

The average eyeball is about the same size as a ping pong ball. There are 20 working parts in your eye, which sounds like a lot, but considering everything it does it really isn’t that many.

The eye works like this:

  • Light enters the cornea, the clear front surface of the eye.

  • The light then travels through the Iris, which controls the amount of light that reaches the back of the eye by adjusting the size of the pupil.

  • The Crystalline Lens, located directly behind the pupil, further focuses the light through a process called accommodation, which helps the eye focus on its subject.

  • Focused light then reaches the Retina, the inner lining of the back of the eye. The Retina converts images into electronic signals that are sent to the Optic Nerve and then gets sent to the Visual Cortex of the brain.


The eye does all of those things faster than you even realize what is happening. So again, take a minute to really think about how awesome the eye is. Now go out and see all the cool things your eyes were made to see!

20/20 Vision... What Does It Really Mean?

You have probably been told your whole life that 20/20 vision is as good as it gets when it comes to eyesight. Most people know the term, but don’t know what it actually means.

20/20 vision is a term used to describe normal visual acuity, or the sharpness and clarity of something at 20 feet. If you have 20/20 vision, an object at 20 feet should look crisp and clear.

Having 20/20 vision doesn’t necessarily mean you have perfect vision. There are other factors that you have to take into account such as depth perception and peripheral vision.

snellen-eye-chart

Vision is typically measured with the use of a Snellen Chart. The combination of numbers and letters vary in size and are used to determine how well you can see objects from a specified distance.

It is important to have your vision tested by an Optometrist or Ophthalmologist. If you feel that your vision is declining, please make an appointment with us and get it checked out.

The Monocle: The Impractical Lens

Monocle (noun): a single eyeglass, kept in position by the muscles around the eye.

So, a monocle is basically a half of a pair of glasses that you have to hold in place with your eyebrow? Sounds like it would be a bit too much work. And what about the other eye? Seems a bit impractical to me.

It is that impracticality that made monocles so popular amongst the wealthy aristocrats in the late 1800’s. A proper Monocle had to be custom made and fitted to your eye, which was an extensive and expensive process that only the wealthy could afford. The Monocle was used as a status symbol as a way to show off ones wealth.

The use of a single lens for magnification can be traced back to Ancient Egypt, but the monocle, as we know it, was invented in Germany in the 1700s and was originally called the Eye Ring. It was made popular by an Austrian optics student named J. F. Voigtlander. He began making Monocles in 1814 and selling them to the wealthy.

Monocles would come in and out of style throughout the 1800s and typically were made out of metal, tortoiseshell or horn. Some high-end Monocles were even made out of Gold and Silver. Though, don’t go trading out your eyeglasses for a customized monocle just yet! The Monocle was never considered a functional solution for eye problems, just as a status symbol for the wealthy.

I spy with my little eye...

I spy with my little eye something blue. If you guessed the Rinkov logo up and to the left, you're right.

We've all played I Spy at one point or another. It's a great way to pass the time, no matter how frustrating it can be that you just can't seem find what you're looking for, especially in those I Spy books!

The first I Spy spotters' guides were developed and originally self-published by Charles Warrell in 1948. Warrell was a British educator and headmaster who believed in active education. His books feature a busy picture or illustration with a number of things hidden within and readers have to find the items listed at the bottom of the page.

FUN FACT: Charles Warrell's alias was Big Chief I-Spy.


After years of success and being picked up by larger publishers, publishing ceased for a number of years, until 1991 when the I-Spy spotters' guide series was acquired by Michelin, who continues to publish the books today.

Scholastic also publishes a line of books similarly titled I SPY. The books also focus on education and learning.

The popularity of the books have led to numerous interactive and digital versions all over the web.

You can play one here: I Spy Games

Strabismus...what's that?

Strabismus is a condition in which the eyes do not align properly. One of the eyes tends to look up or down or to the side while the other eye is looking straight ahead.

Congenital Strabismus is the most common type, which is when children are born with misaligned eyes. There are cases in which Strabismus will occur later in life and will cause double vision, and likely be the result of a more serious medical issue.

eye exam

Strabismus can be treated multiple ways. One form is the use of optimal eyeglasses and patches that force the use of the weaker eye which strengthens the muscle. This will allow the eye to become properly aligned with the other eye.

Surgery is also a method used to treat Strabismus. An Ophthalmologist will strengthen or weaken the muscle depending on the case.

If you think that you or a loved one may have this condition, you should schedule a visit with your eye care provider.

My Eyelid Won't Stop Twitching! - HELP!

eye-343757_1920


It’s happening…again.


You’re staring at your computer screen and all the sudden that annoying little eyelid twitching starts happening. Your eyelid has been twitching on and off for the past few days and it’s really starting to become obnoxious.

Where did this twitch come from? Your eye hasn’t always twitched like this. And why is it happening now? Do you need to take a trip to your eye doctor? Maybe you do, but probably not.

Myokymia is defined simply as involuntary muscle spasms.


Muscle spasms can happen throughout the body and often times we have no idea why it happens. You have probably experienced benign muscle spasms in your arms, legs or back before.

Common causes of eyelid twitching:



  • Stress

  • Lack of sleep

  • Eye strain

  • Too much caffeine or alcohol intake

  • Dry eyes

  • Nutritional imbalances

  • Allergies


To alleviate eyelid twitching:



  • Get a good night's sleep

  • Keep eye moist with eye drops

  • Apply a warm compress to your eyes

  • Decrease caffeine or alcohol intake


If eyelid twitching persists for more than one week, twitching is causing the eye to completely close, you experience other facial muscle spasms, your eye is swelling or expelling discharge, or your eyelid is drooping you should visit your eye care provider to check for a more serious condition.

Are We Seeing Things? - Optical Illusions

Optical Illusions. They mystify the mind and make us feel as though we're losing it. But how do they work?

Magic? Can't be.

Optical illusions work because they mess with your perception of reality. The information your eyes gather and send to your brain can be deceptive and misleading to your brain. Your brain creates a perception of the information the eye has gathered, that does not match with reality. Optical illusions use color, light and patterns to create this effect.

There are 3 main optical illusions:


1. Literal Illusion - Create different images than the objects they are made up of.


literalillusion

Do you see an elderly couple gazing into each others eyes, or two people sitting down, or both?

2. Physiological Illusions - Caused by the over stimulation of a specific type. Typically, brightness, color, size, position, tilt or movement.
physiologicalillusion
In this illusions, known as the Hermann-grid illusion, how many dots do you actually see? Do the dots disappear when you look directly at the intersection of the white lines?

3. Cognitive Illusion - The result of our unconscious assumptions about the world.


cognitiveillusion

In this original version of Young Girl-Old Woman, which do you see? Can you make your brain switch between seeing both the young girl and the old woman?

 

Perception really is everything, ay?
