Professions that Require the Best Vision

Professions that require the best vision- Traffic control-OKC Optometrist

Air Traffic Controller

Air traffic controllers coordinate the movement of air traffic to guide aircrafts to and from destinations and ensure aircrafts keep a safe distance apart.

Karen Carney, Marketing Coordinator with the Will Rodgers Airport in Oklahoma City says, “An air traffic controller must past a yearly vision test and pass with 20/20 vision or have corrected 20/20 vision for both near and far distance, and intermediate vision (eyesight at approximately arm’s length) for each eye. The second round of testing is the color vision requirement portion.”

The color vision test is called the Aviation Lights Test (ALT), which tests the ability to differentiate among colors used in the Air Traffic Controller (ATC) practice.

Professions that require the best vision- Air Force Pilot-OKC Optometrist

Air Force Pilot

From the U.S. Air Force, general vision requirements for Air Force pilots include normal color vision, uncorrected near vision cannot exceed 20/200 and uncorrected distant vision cannot exceed 20/40. However, both distance and near vision must be 20/20 or better. Pilots must meet refraction, accommodation and astigmatism requirements.  Some disqualifications may apply if you’re colorblind, have problems with depth perception or have had laser eye surgery.

Fire Fighter

To become a firefighter it is highly recommended to have 20/20 vision.

Oklahoma State Firefighters Association Executive Director Phil Ostrander states, “The eyesight standards for firefighters are set to a high standard because as firefighters work 25 – 35 years or more, they still have quality eyesight when they conclude their service.”

Firefighters are afforded the opportunity under the NFPA Standard and Pension Administrative Rules to have corrected vision by contacts or glasses. They can also place specially adapted eyeglasses inside of their breathing air masks if desired.

Ostrander also adds, “There are many things that occur at a fire scene and firefighters must have all of their senses on high alert. This is for their safety and for the safety of those they have sworn to protect. While inside a structure, firefighters are generally unable to see more than a couple of inches. When the fire is extinguished, or while outside the structure, they must be able to see and identify the numerous hazards that are present. Eyesight is very important in so many ways that firefighters do their best in these hazardous situations to protect themselves from eye injuries as well as the many other potential hazards they face.”

T.J. Radford with the Oklahoma City Fire Department says, “As a firefighter there are many senses that we use when duty calls. From medical calls to fires, we rely on one important sense, our eye sight. Having great eye sight in this profession can save your life as well as others.”


Police Force

To become a police officer visual requirements include uncorrected vision of no less than 20/100 in both eyes and corrected to 20/20. Each state and county has different requirements but all require good vision for emergency situations and gun handling. Color vision tasks are also crucial when identifying suspects.



The Navy Seals, one of the toughest military programs to get accepted to, requires uncorrected vision in the better eye can be no worse than 20/70, the worse eye no more than 20/100. Both eyes must be corrected to 20/20. Color deficiencies require approval.

If you’re considering pursuing one of these careers, find out what kind of vision you have with an eye exam from your Oklahoma City optometrist, Dr. Kenneth Guthrie.

Influential Eyeglasses of the Ages

People have been wearing eyeglasses since the early mid 1700’s. Legends such as Benjamin Martin and Benjamin Franklin were some of the first to start using eyeglasses to help with daily activities such as reading and writing, just as we do today. Eyeglasses have evolved over the ages both in design, prescription and materials.

Interestingly enough, just as fashion trends come in and out of style, styles of spectacles do the same. Some spectacles lived past their initial introduction and still seem to exist in current fashions, while others faded and never returned.

Benjamin Martin styled frame

1756 Benjamin Martin Spectacles

Benjamin Martin, an obstetrician in London, England, created one of the very first pair of spectacles to correct vision and be used as a reading aid. Martin wrote an essay called “Visual Glasses,” describing how lenses were rounded out with Ox horn material and how spectacles can be improved. Spectacles were also made out of tortoise shells, which only stayed popular for another two generations until steel became available.

Round Lens Double Folding Frame

1784 Benjamin Franklin Temples

These Benjamin Franklin frames, also known as double folding temples were worn by the one and only Benjamin Franklin. You have probably seen these glasses in many historical pieces and history books. Benjamin Franklin invented the very first bifocals changing the eyeglass industry forever.

Antique Straight Temple Eyeglasses

1833 Straight Temple Spectacles

Straight temple spectacles were machine produced from 1833 until WWI. These lenses were usually oval shaped, however sometimes were square or octagon shaped. In this era, colored lenses were starting to be used for medical purposes.

Antique Plastic Pince-Nez

1902 Pince-Nez Glasses

Made popular by President Theodore Roosevelt, the Pince-Nez glasses were extremely trendy in the early 20th century. This style is now often associated with dapper top hat-wearing men. However, this style experienced short lived popularity, most likely because of its inconvenient design.

1960s Black Plastic Eyeglasses

1950 Thick Plastic Frames

Starting in the 1950’s, the thick plastic style frames remained popular until the 1970’s. This bold look was worn by the famous Buddy Holly. Today, this trend has made a comeback with the younger generation and on occasion worn without a prescription.

Black Plastic Eyeglasses

1960 Cat Eye Lenses

In the 1960’s color started emerging with plastic framed eyeglasses. Vibrant colors like bright orange, blue and red started to resemble this colorful time in history. With large oval type lenses to “cat eye” lenses for women, these styles are still around today giving people that perfect vintage look.

Vintage Wire Rim Eyeglasses

1970-1980 Aviator Glasses

Originally designed by Ray-Ban for fighter pilots in 1937, aviator sunglasses have been remained popular through various stages of history. While the sunglasses were perhaps made most famous by Tom Cruise in his role in Top Gun, the aviator glasses were not as popular. Though some men wore this style up into the 90’s, today these are seen as a very retro and vintage frame.

1990 wire frames

1990 Thin Wire Frames

Wire frames and rimless glasses were the hippest style of the 1990’s.  These almost non-existent frames came in oval and rectangular shaped glasses and sometimes even tinted lenses. While this style hasn’t made a comeback yet, other trends from the 1990’s have started to creep their way back into popular culture.

Women's Plastic Designer Eyeglasses

2010 Bold Large Frames

These frames combine stylistic elements from the 70’s and 80’s with their large frames and square shape. Today, the trend of thick plastic frames continues to dominate and will probably be here to stay.

Vintage Combination Browline Frame

2016 Vintage Round Lenses

When it comes to the hottest trends for eyeglasses in 2016, it seems like retro round lenses are coming back around. Round, colorful lenses are popping up from major designers like Michael Kors and Ray Ban.

If you are interested in more influential eye glasses, Optometry Cares is a non-profit organization that manages the Museum Collections held at the Archives & Museum of Optometry. This organization strives to represent the history of eye wear, the optical industry, and the American Optometric Association.

Allergies and Your Eyes

Allergies and Your Eyes

Oklahomans are known for battling the extremes. Extreme weather changes that lead  to extreme allergies are a common problem. The Weather Channel ranked Oklahoma City number 10 of 40 cities in America for the worst allergies.

There are several things that you can do to help fight these allergies.

From over the counter products for your eyes, natural remedies you can do at home to visiting your local Oklahoma City optometrist, to discuss options for eye relief all are good options.

Over-the-counter artificial tears are the first go-to product for eye allergy sufferers. When purchasing over-the-counter treatments, look for products containing an antihistamine. Antihistamines are compound that inhibit the physiological effects of histamines, the compounds our body uses to fight invaders, and are especially used in the treatment of allergies. Look for products like Visine, Zaditor or Opcon eye drops.

Natural home remedies are another option.

For example, Nettle leaves contain histamines and if made into a tea, contain anti-inflammatory and antimicrobial properties that can help eye allergies. For puffy eyes, eucalyptus essential oil is recommended for its anti-inflammatory properties. Add the eucalyptus oil to a diffuser or a steam bath to open up sinuses and reduce swollen eyes. Another at-home method is to use a cold compress on your eyes. Put some ice cubes in a clean washcloth and place on your eyes for 5-10 min each day for relief.

Speaking of home remedies, there are several ways you can maintain an allergy-free environment in your home. Before or after battling outside allergies, try these tips:

  • Wash your dirty clothes as soon as possible, as pollen and particles can gather on your clothes throughout the day.
  • Take a shower as soon as you get home to rinse out the particles that have accumulated in your hair. Showering often will also help keep your pillow case clean and allergy free.
  • Wash your sheets, pillowcases and blankets at least once a week to keep dust and particles at bay.
  • Do some deep cleaning and keep your windows closed during allergy season. This will help prevent dust and particles collecting on window blinds and surfaces.
  • Don’t forget to grab your sunglasses on your way out the door! Sunglasses can help block pollen from getting into your eyes.

Your optometrist can also prescribe you medications for your eye allergies. In some cases, symptoms may be more than just allergies. Consulting an optometrist ensures you will be evaluated and tested for more severe and serious eye infections.

If you are an Oklahoma student or faculty member suffering from allergies, Dr.Kenneth Guthrie offers 10% discounts off eye exams to local universities!



Contact Lenses, What are your options?

Tracking a pitch into your bat can be a challenge for a baseball player in glasses. Not only is the eye tracking from uncorrected vision to corrected vision, there’s a physical obstruction (the frame of the glasses) between the two.This problem is common to athletes, but certainly isn’t limited to them.

So you want to ditch the glasses but don’t know where to start?

You’re not alone. Actually, 20% of Americans who need vision correction wear contact lenses. Contacts used to be made of thin plastic; now almost all contacts are made of Silicone Hydrogel. Silicone Hydrogel is a soft gel-like lens that covers the entire cornea; this material increases oxygen to the eye and is the most popular contact lens among consumers, accounting for 67% of prescriptions.

The best way to choose contacts is to find lenses that fit your lifestyle

If you like the idea of having a fresh pair of contacts every day with no solution or cleaning to worry about; you need daily disposable contact lenses. For others, the convenience of extended wear contacts – typically worn for up to a week at a time – can be appealing. Extended wear contacts are especially useful for people whose jobs or lifestyles make it difficult to properly clean their contacts. Below are some examples of contacts that may match your lifestyle:

Living at the office- Staring at a computer screen all day can be harsh on your eyes. When you focus on an object, you strain your eyes and blink less- frequently. People blink 1/3 less than normal when working on a computer. For the people with dry eyes at the office from working, choose a high moisture and high oxygen contact lens like Proclear from CooperVision, Air Optix from Alcon, or 1 day Acuvue True Eye.

play-ball-1438249-640x512Athletes – As mentioned before, contacts give you better peripheral vision, stay in place and are not in the way like eye glasses. Also, contacts can offer UV protection against the sun. The best lenses for this lifestyle would be UV protection 1 day Acuvue moist lenses.




For people on the go- You simply just don’t have time to worry about your contacts. Your calendar is full of long days and long nights. The best contacts for you are reusable lenses like Biofinity and Proclear compatibles from CooperVision. These lenses are good for moisture and bringing the most oxygen to the eyes for longer wears.

Now that you have more of an idea about the type of contact you may need, it’s time to choose a brand. See the chart below to quickly compare Acuvue, Alcon and CooperVison’s contacts based off of availability, technology, and rebates offered.

Choosing your brand:

Contact Lenses, what are your options

These contacts are available to order directly from Dr. Kenneth Guthrie and shipments arrive within 3-4 business days. Rebates are also available on yearly supplies. For any further questions, please call Dr. Kenneth Guthrie at 405-753-9006.


7 Tips to Relieve Computer Vision Syndrome

7 tips to relieve computer eye strain

Since millions of people utilize or work with computers every day, it is no surprise that it can take a toll on your vision. Computer eye strain, commonly referred as Computer Vision Syndrome (CVS), affects up to 90% of people who work with computers on a daily basis.

What Causes Computer Vision Syndrome?

According to the American Optometric Association, Computer Vision Syndrome is caused by the excessive eye focusing and eye movement required for the digital screen. The letters on the computer screen are not as sharply defined as viewing on paper, and the level of contrast of the letters to the background is reduced. The presence of glare on the screen can also cause viewing difficulty.

People who suffer from CVS might deal with symptoms such as dry eyes, twitching, blurred vision, headaches, or neck and upper back pain. The physical discomfort is temporary and based on your prolonged use of a computer monitor. However, if no preventative steps are taken to relieve the strain, your pain may worsen over time and lead to more serious problems. Here are seven tips to relieve your strain:

  1. Screen distance

If your computer screen is too far away or too close, you may be unnecessarily staining your eyes. Take the time to re-position your screen slightly lower than eye level to create an angle where neck naturally rests to allow less work for your eyes.

  1. Blink often

If you have dry eyes, it might be because you are not blinking enough while you are working on the computer. Be conscious of your blinking habits and make sure to take a 20 second break to close your eyes to them a chance to moisten and lubricate.

  1. Take Regular Work Breaks

Take regular work breaks by relaxing at your desk. You can close your eyes, breathe deeply for 15 to 30 seconds to regather your thoughts and allow your eyes a resting period.

  1. Eye Exercises

When you are taking regular work breaks, you can set aside time to do a few ‘eye exercises’. Make sure to roll your eyes for increased lubrication, glance in different directions to keep your eyes alert, quickly visually scan the room, and focus on something other than the computer screen for at least a minute for a refresher.

  1. Proper Lighting

Ideally, you would like to avoid glare from overhead lights or the sun by positioning your monitor in the most glare resistant angle. If the glare in unavoidable, you might consider investing in a glare resistant monitor to relieve the strain. You can also down the brightness and increase contrast to make the screen easier on your eyes.

  1. Take Vitamins

You can help your eye health problems by taking the necessary vitamins. Vitamin A is essential for healthy vision because it reinforces the macular tissues in your eyes keeping your vision sharp and clear. Vitamin A is found in egg yolk, cheese, milk, and butter, but can be taken in supplements.

  1. Get regular eye exams

This is the most important step you can take to treat or prevent Computer Vision Syndrome. If you are having severe symptoms such as migraines, your physician can look into what triggers your diagnosis and help you treat your pain. It is also important for you to monitor your vision to make sure changed significantly due to strain.

If your pain persists or gets worse, contact us to schedule your comprehensive eye exam, so we can help you relieve your strain.

What Color is the Dress? The Science of Your Eyes

If you were tuned into any social media platform this week (February 26th), you probably saw many discussions and pictures of this dress:

White and Gold or Blue and black - the science

The debate came from the popular social site, Tumblr, where people debated whether the dress was white and gold, or blue and black. Celebrities, news anchors, major websites and politicians were all arguing what their eyes saw in this picture. It was revealed later in the day that the dress is, in fact, blue and black.

Why did some see white and some see blue?

This debate boils down to the science of light and color perception in your brain. The reason different people see different colors have to do with retinal cones that perceive color in light. When one person sees white and gold, it is actually caused by a difference in the development of these retinal cones and the transmission of this information to the optic nerve. Most commonly, the color discrepancy gene is found in males because the genes that produce photopigments are carried on the X chromosome.

You have 6 to 7 million retinal cones, and 2% of them perceive blue. These blue cones are the most sensitive to light, which causes some differences in perception of blue among humans depending on the lighting conditions. This is why there were so many discrepancies between white and gold vs blue and black.

Why did some see black and some see gold?

As for the black part of the dress, this has to do with the sensitivity of the “rods,” which perceive shades of dark to light, not color. These rods are active in low light, so people who can see better in dim light have more active/sensitive rods. If you saw gold instead of black, it may be an indicator that your vision at night isn’t as strong as someone who sees black. Have no fear, though, the discrepancies aren’t enough to warrant panic.

However, if this color debate has given you any reason to be concerned about your vision, you can always come in for an eye exam and we can check you out!

5 Eye Makeup Health Tips

For a lot of women, applying eye makeup is part of their daily beauty routine. Unfortunately, in many cases, women aren’t aware of the negative impact makeup can have on their eye health. Bacteria build up, chemical expirations, and fungi growth are just a few ways makeup can harm your eyes.

We won’t tell you to give up wearing makeup; so instead, here are a few tips to keep your eyes healthy and beautiful:

1.     Mark Expiration Dates

Different types of eye makeup expire at different times, so it’s best to mark the expiration date with a permanent marker right when you open the package. That way, you don’t have to remember the date, and you have a daily reminder that your product is going to expire. Here is a handy guide to eye makeup expiration dates:

EYE MAKEUP Expirations Infographic

Always check your product’s packaging for the manufacturer’s expiration guidelines.

Once your expiration date comes – throw the product away. Even though you may still have “valuable” product left in the container, the health risks aren’t worth it. Plus, it gives you an excuse to shop for something new!

2.     Sanitize Your Makeup

You should also be cleaning your makeup products regularly, especially if the product is easily accessed such as in a jar or compact. Beauty Report by B has the following recommendations:

  • Compact Powders: Mist with rubbing alcohol
  • Eye Pencils: Sharpen to remove bacteria, and clean sharpeners as well with a solution of white vinegar, warm water and dishwashing liquid
  • Retractable liners: Wipe with a tissue and mist with rubbing alcohol
  • Cream concealers (in a jar): use a clean cotton swab for application, never stick fingers or a dirty brush directly into product

3.     Clean Makeup Brushes & Sponges Often

You should clean all makeup brushes and sponges once a week. Although this may be a hard task to remember, it is extremely important because it will prevent your eyes from developing styes or conjunctivitis.  Makeup Geek has a great tutorial on How to Clean Your Brushes Like a Pro.

4.     Take Care with Loose Powders

Mineral makeup is very popular, but much of it comes in loose powder form. Particles can easily fall into your eye during application, so hold a tissue under your top eyelashes to catch the dust. Also, make sure you aren’t getting too much product on to your brush to prevent heavy fallout.

5.     Remove Eye Makeup Entirely Before Bed

The number one makeup-related cause of eye infections is improper removal. If you don’t remove all of the product, it can stick to your lashes and cause clogged pores, resulting in a stye or pimple. Also, leaving eye makeup on overnight gives bacteria and fungi a chance to settle in – which is never a good thing.

Many face washes such as Neutrogena’s Ultra Gentle Facial Cleanser line can remove makeup and dirt all in one step. If you use waterproof mascara or eyeliner, though, you should use an eye makeup remover specifically for this purpose. Loreal’s Clean Artiste WaterProof Makeup Remover is affordable, and works well with a soft cotton pad.

If you do find yourself with an eye infection or irritation, please don’t hesitate to contact Dr. Guthrie or your local optometrist – your vision could be at stake!
