Online Eye Test: Find Your Blind Spot in Each Eye!

Everyone has a BLIND SPOT in their vision of each eye.

Take this FUN test to check it out for yourself !!

Look at graphic of the cross and the circle at the top of this post.

Sit at your computer with your nose pointing in between the cross and the black circle.

Cover your LEFT eye and stare at the cross with your RIGHT eye.

Now SLOWLY move towards the computer screen while still staring at the cross with your RIGHT eye.

At somewhere around 10-14 inches from the computer screen – the black circle will disappear and the area where the black circle was…will now be all white – this is your BLIND SPOT.

If you move closer to the screen or farther away –  the circle will re-appear.  At just the right distance – the circle will disappear.

Now try the OTHER eye…but this time cover your RIGHT eye and look at the CIRCLE with your LEFT eye…..move closer and you will see that the CROSS now disappears!!

Your eye has an inner lining which is made of a sheet of nerves.  This sheet of nerves is responsible for your vision and what you see and it is called the RETINA.  There is a “hole” in the sheet where the Optic Nerve enters the eye.  This area is called the Optic Nerve Head.

Photoreceptors are cells in the retina that detect light and allow you to perceive “vision”.  On the optic nerve head there are NO photoreceptors.  Thus, there is no light or vision detected at this spot in the retina.  This is your “Blind Spot”.  Every eye has a blind spot….your blind spot in your right eye is slightly on your right and your blind spot in your left eye is slightly on your left.

Your brain automatically “fills in” the blind spot area for you…..

Now try it AGAIN with the above green and yellow graphic….but this time you will notice that when you move to just the right distance , the circle will disappear and your brain will fill in your blind spot WITH YELLOW when you are looking with your right eye (left eye covered)….and your brain will fill in your blind spot WITH GREEN when you are looking with your left eye (right eye covered)!!  Your brain automatically matches the surrounding colors when it “fills in” visual information for you.

Cool huh??

Your brain can even “fill in” missing information for you…..in the above graphic, you’ll notice that when you cover your left eye and look at the cross with your right eye – the brain will “fill in” your blind spot (the area where the circle is).  You will see that your brain fills in the line for you.  Keep looking at the cross – don’t look back at the circle – or you will will see the circle again.

Try it AGAIN with the above graphic while looking at the cross with your right eye (cover your left eye) – your brain will put a red circle where your blindspot is….it is “filling in” the “missing information” !!

Amazing.

Video – Sunglasses are like Sunscreen for your Eyes: Protection from Aging Changes and Some Forms of Eye Cancer

********

CLICK HERE

TO SEE A FOX NEWS VIDEO ABOUT EYE CANCER AND PROTECTION WITH SUNGLASS WEAR

The sun can cause aging changes to your skin… and also to your EYES.

Macular Degeneration and Cataracts are aging changes that can be brought on earlier in your life by exposure to the sun its ultraviolet (UV) radiation.  Wearing sunglasses with good UV protection can be like wearing sunscreen for your eyes.

There are many different types of eye cancer that can affect any part of the eye.  A patient can get cancer on the Eyelids, the Conjunctiva (the “skin” over the white of your eye), the Iris (the colored part of your eye), the Optic Nerve (the nerve from the eye back to the brain), the Retina (the nerve layer inside your eye – responsible for your vision), the Choroid (the blood vessels beneath the retina) and more.

The types of cancers that usually affect the skin (aka on the eyelids….basal cell carcinoma, squamous cell carcinoma, melanoma etc.. ) can be the same types of cancers that particularly thrive in sunlight and UV exposure – just like any other type of skin cancer.

EVERYONE (including children) should be wearing sunglasses with UV protection any time they are outdoors. People who are particularly vulnerable are those with with blue eyes, light complexions, work outdoors, have had any PREVIOUS skin cancer or who are taking any medications that make them more light sensitive.

Routine yearly eye examinations are the KEY to early detection and treatment for any types of eye cancer and any other type of eye disease

Diabetic Eye Examination and Diabetic Retinopathy

Informative Video from the Joslin Diabetes Center

Diabetes is the #1 Cause of Preventable Blindness in the U.S. Most of the time there are NO symptoms of diabetic eye problems.  You can have diabetic retinopathy and not even know it.  Many patients can still have fairly good vision even with advanced stages of diabetic eye disease (diabetic retinopathy).   

Diabetic retinopathy is a term used for pathology (bleeding, fluid build up and/or abnormal blood vessel growth) in the nerve lining of the inside of the eye that we use for our vision – called the Retina.

This kind of diabetic pathology is caused when elevated blood glucose (blood sugar) damages the blood vessels in the retina – causing bleeding and fluid build up in and around the retina.  Blood sugar is monitored via blood glucose testing and Glycosylated Hemoglobin (HbA1c) testing (which tells the primary care doctor the average blood glucose in someone’s blood for the past few months – not just the glucose reading on the day of the testing).

Therefore, it is essential for diabetics to have a comprehensive eye examination at least every 12 months – even if their blood sugar is under control. A comprehensive examination should include a dilated eye exam with retinal imaging (digital retinal photography) to document the presence or absence of any diabetic retinopathy.  Retinal photography is essential to pick up and document any subtle diabetic changes in the retina from year to year.

The sooner any diabetic eye problems are diagnosed and treated, the lower the risk of visual loss and/or blindness from diabetic related complications.

So, if you are diabetic or know anyone who is diabetic – a yearly dilated diabetic eye exam is essential for prevention of vision loss from diabetes.

Children’s School Problems May Be Caused by Undetected Vision Problems

Click on the above “Fuzzi” banner to see a Video for you

and your child to view together…

Often children can not express to adults that they may be having problems with their vision. They may not even realize that their vision is blurry or “Fuzzy”.  They may be falling behind or having trouble in school…for an “unknown” reason.  That “unknown” reason may be due to possible vision problems – even if they are able to PASS the Vision Screening at school or at the Pediatrician’s office.

Click on the “Fuzzi is having trouble at School” banner above and you can watch the video with your child.   It may open up a discussion between you and your child about his or her vision.  If your child can identify with the problems that “Fuzzi” is having at school – then its time for your child to have a comprehensive eye examination.
