My Eyes Feel Like the Sahara!

Itching, burning, watering, red, irritated, tired eyes… what is a person to do? The symptoms aforementioned are classic sign of Dry Eye Syndrome (DES), which affects millions of adults and children. With increased screen time in all age groups, the symptoms are rising.

What causes this? One reason is that when we stare at a computer screen or phone, our blink reflex slows way down. A normal eye blinks 17,000 times per day. When our eye functions normally, the body usually produces enough tears to be symptom free, however, if you live in a geographical area that is dry, or has a high allergy rate, your symptoms could be worse.

Dry eye syndrome can be brought on by many factors: aging, geographical location, lid hygiene, contact lens wear, medications, and dehydration. The lacrimal gland in the eye that produces tears, in a person over forty years old, starts slowly losing function. Females with hormonal changes have a higher incidence of DES (dry eye syndrome). Dry, arid climates or areas with high allergy causes lend to higher […]

Activities That Can Change Your Eye Pressure

There have been studies undertaken over the past several years to try and understand if there are any of our day-to-day activities that either help or hurt the management of glaucoma.

Most of the studies demonstrated very little impact on the course of glaucoma. Here are some of the things researches have looked at.

Aerobic exercise: This means doing something at least four times per week for more than 20 minutes at a time that raises your pulse rate to a level that makes your heart work harder. Going from a sedentary lifestyle to active one with aerobic exercise resulted in a very slight decrease in baseline eye pressure.

Yoga: A study conducted at the Mount Sinai Health System (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0144505) showed a significant increase in eye pressure with any head-down positioning. People with glaucoma would be wise to avoid any exercise that involves a position where your head is lower than your heart.

Weight lifting: Holding your breath while exerting yourself (called the Valsalva maneuver), is also a time when your eye pressure can go sky high. […]

What Tests Might I Have During My Eye Exam?

Visual Field

The visual field test is designed to see how well you see outside of the center part of your vision (peripheral vision).

When we test your vision on the basic eye chart it is only testing how well you see right in the center and gives us no idea if you can see out away from the center. Your peripheral vision is very important because it gives you the ability to move around your environment without running into things.

There are several diseases that can severely impact your peripheral vision while leaving central vision unaffected. Some people can have perfectly normal 20/20 central visual acuity and have almost complete loss of their peripheral vision.

The main culprits that can have a big impact on your peripheral vision long before your central vision are glaucoma, some retinal diseases such as retinal detachments or retinitis pigmentosa, and some neurological problems like brain tumors, strokes, pseudotumor cerebri and multiple sclerosis.  

Most visual field tests are now done on an automated machine that flashes lights in your […]

Eye Safety During the Holidays

Your Eyes Are A Precious Gift–Protect Them During The Holidays

“I want an official Red Ryder, carbine action, two-hundred shot range model air rifle!”

“No, you'll shoot your eye out.”

This line from “A Christmas Story” is one of the most memorable Christmas movie quotes ever. Funny in the movie, but the holiday season does present a real eye injury threat.

For those who celebrate Christmas, that risk begins even before the actual day.

Some of the most frequent holiday-related eye injuries come from the Christmas tree itself.

Holiday eye safety begins with the acquisition of the tree. If you are cutting down your own tree, please wear eye protection when doing the cutting–especially if you are going to be using a mechanical saw such as a chain saw or sawzall. You need to also be careful of your eyes when loading a tree on top of the car. It is easy to get poked in the eye when heaving the tree up over your head.

Once back at home, take care to make sure no […]

2020 Most Dangerous Toys

Christmas is one of the most joyful times of the year… thoughts of cookies, decorations, family gatherings, and toys abound. Birthday parties for kids add to the list of wonderful memories as well. But there are a few toys that may not make memories so fun because of their potential for ocular harm. The American Optometric Association lists dangerous toys each year to warn buyers of the potential harm to children’s eyes that could occur because of the particular design of that toy.

Here is a sample of that toy list:

  • Laser toys and laser pointers, or laser sights on toy guns pose serious threat to the retina, which may result in thermal burns or holes in the retina that can leave permanent injury or blindness. The FDA’s Center for Devices and Radiological Health issues warnings on these devices at Christmas peak buying times.
  • Any type of toy or teenage gun that shoots a projectile object. Even if the ammo is soft pellets, or soft tipped it can still pose a threat. Even soft tipped […]

Sports and Eye Injuries

If you were to do a Google news search for sports-related eye injuries today, chances are you'd find multiple recent stories about some pretty scary eye injuries.  Whether they are professionals, high school or college athletes, or kids in community sports programs, no one is immune to the increased danger sports brings to the eyes.

Here are some facts about sports-related eye injuries:

  1. Eye injuries are the leading cause of blindness in children in the United States and most injuries occurring in school-aged children are sports-related.
  2. One-third of the victims of sports-related eye injuries are children.
  3. Every 13 minutes, an emergency room in the United States treats a sports-related eye injury.
  4. These injuries account for an estimated 100,000 physician visits per year at a cost of more than $175 million.
  5. Ninety percent of sports-related eye injuries could be avoided with the use of protective eyewear.

Protective eyewear includes safety glasses and goggles, safety shields, and eye guards designed for individual sports.

Protective eyewear lenses are made of polycarbonate or Trivex.

Ordinary prescription glasses, contact lenses, […]

Giving the Gift of Sight

And old Creek Indian proverb states, "We warm our hands by the fires we did not build, we drink the water from the wells we did not dig, we eat the fruit of the trees we did not plant, and we stand on the shoulders of giants who have gone before us."

In 1961, the Eye Bank Association of America (EBAA) was formed. This association stewards over 80 eye banks in the US with over 60,000 recipients each year of corneal tissue that restores sight to blind people. Over one million men, women, and children have had vision restored and pain relieved from eye injury or disease. The Eye Bank Association of America is truly a giant whom shoulders that we stand upon today. Their service and foresight into helping patients with blindness is remarkable.

It is important to give back the gift of sight. You may be asking, “how does this affect me?” On the back of your drivers license form there is a box that can be checked for being an organ donor. Many […]

Should I Be Scared of My Astigmatism Diagnosis?

The word “astigmatism” is used so much in the optometric world that most people have talked about it when discussing their eye health with their doctor.

“Astigmatism” comes from the Greek “a” – meaning “without” – and “stigma” – meaning “a point.” In technical ocular terms, astigmatism means that instead of there being one point of focus in the eye, there are two. In other words, light merges not on to a singular point, but on two different points.

This is experienced in the real world by blurred, hazy vision, and can sometimes lead to eye strain or headaches if not corrected with either glasses or contact lenses.

Astigmatism is not a disease. In fact, more than 90% of people have some degree of astigmatism.

Astigmatism occurs when the cornea, the clear front surface of the eye like a watch crystal, is not perfectly round. The real-world example we often use to explain astigmatism is the difference between a basketball and a football.

If you cut a basketball in half you get a nice round half […]

Differing Functions of Ophthalmologists, Optometrists, and Opticians

Knowing the difference between the various specialties in the eye care industry can be confusing, especially given the fact that they all start with the same letter and in many ways sound alike.

So, here’s a breakdown of the different monikers to make life a little less confusing for those wanting to get an eye exam.

Ophthalmologists

Ophthalmologists (pronounced “OFF-thal-mologists”) are eye doctors who went to four years of undergraduate university, four years of medical school and four to five years of ophthalmic residency training in the medical and surgical treatment of eye disease.

Many ophthalmologists then go on to pursue sub-specialty fellowships that can be an additional one to three years of education in areas such as cataract and refractive surgery, cornea and external disease, retina, oculoplastic surgery, pediatrics, and neuro-ophthalmology.

Ophthalmologists are licensed to perform eye surgery, treat eye diseases with eye drops or oral medications, and prescribe glasses and contact lenses.

Optometrists

Optometrists are eye doctors who went to undergraduate university for four years, then went on to optometry school for four years.
