How to Know if Your Vision is Affecting Night Driving

While some people simply have an aversion to night driving, many people feel they are taking their lives in their hands when they venture across town after dusk. What causes the difficulty of night driving as we age? The Orlando LASIK expert, Doc Brock, has seen patients with several unique experiences who have dealt with night driving aversion. Read below for the cause of many of these disorders.

Cataracts The buildup of debris within your lens can cause it to become more opaque as you age. This causes lights to appear with halos around them and your vision may become blurry. Replacing the damaged lens with a lens of your prescription will allow you to see more clearly almost immediately.

Lack of Vitamin A and Zinc Vitamin A supports retinal health. Zinc increases vitamin A’s capacity to work. While most Americans consume enough of both, those with health issues that do not allow proper absorption of nutrients – Crohn’s disease, celiac disease, or any type of digestive bypass procedure – may experience a deficiency in many vitamins and nutrients. This proves that the old adage is correct, eating more carrots that are high in vitamin A can help your night vision.

Diabetes Mellitus An excess of blood sugar over a number of years damages both the blood vessels and nerves inside the eye. Diabetes can result in early or accelerated cataract formation. When a cataract develops, light becomes scattered, and often results in glare and haloes. The ophthalmologists at Magruder are experts in cataract surgery and the safest and most effective modern techniques for fixing this problem.

Have the Orlando LASIK experts at Magruder examine your eyes to determine whether you are a candidate for a LASIK procedure. With so many different technologies for better vision available, it will definitely be worth the effort to call 407-843-5665 and speak with one of our staff. Our goal of Correcting Vision – Changing Lives can be the difference between maintaining your safety while still enjoying life.


How Allergies Can Mimic Pink Eye

Have you ever been caught between allergies and pink eye? Wondering what the clear-cut difference is while making a list of your symptoms? The Orlando ophthalmologist at Magruder Laser Vision answers many of your questions below, providing you with some insight on how to tell these tricky problems apart.

Signs of Conjunctivitis

Pink eye, or conjunctivitis, is an infection of the conjunctiva – or covering - of the eye and inner eyelids. You may be diagnosed with one of two types of conjunctivitis, bacterial or viral.

Bacterial conjunctivitis is known for its thick, sticky discharge, especially when you first awaken. Sometimes the discharge physically glues the eyelids together until you are able to rinse your eyes with water. The discharge may appear green, grey, or yellow and can affect one or both eyes. A round of antibiotics should have you cured in no time.

Viral conjunctivitis’ discharge is clear and often resembles excess tears. Swelling and tenderness near the ears, coughing, sneezing, congestion, and a runny nose are all signs of a viral infection. Similar to the common cold, viral conjunctivitis does not require prescription medication. Bed rest and time will help clear your eyes.

Signs of allergies:

“Seasonal” allergies, or allergic rhinitis, may appear at any time of year, with the most common reactions due to dust mites, pet dander, mold, and certain types of tree and plant pollen.

Other symptoms include a runny nose, congestion, dry or irritated throat, sneezing upon waking, inability to hear normally, and drainage from your nose and throat. You may also experience headaches, wheezing, cough, and difficulty breathing in more extreme cases of allergic rhinitis.

As if it couldn’t get any worse, some unfortunate patients suffer from allergic conjunctivitis, which is pink eye caused by allergens. These symptoms include sneezing, itchy nose and throat, congestion, and photophobia (light sensitivity). Allergic conjunctivitis is not contagious.

Headaches? Your Vision Might be Changing

Headaches? Your Vision Might be Changing

Many headaches are caused by eye strain, which can be alleviated by something as simple as adding task lighting to your work surface. On the other hand, some headaches are more serious and better suited for an appointment with ophthalmologists at Magruder Laser Vision.

The Ugly Side Effects of Allergies

As if summer allergies were not bad enough with all the sniffling, nose blowing, blurry eyes, and sneezing, they can also lead to some pretty ugly side effects. Many of these changes affect the eyes, and the team at Magruder Laser Vision wants to give you a better understanding of changes considered usual and those that may require a visit to your Orlando ophthalmologist. Dark Circles Under Your Eyes

Discoloration under your eyes is generally due to the blood vessels under your eyes, which have expanded slightly to allow free passage of blood to the affected area. The puffiness is edema, or a small bit of fluid that normally escapes from the blood vessels when an area is injured or infected. Unless these symptoms impede your vision, you do not need to see an ophthalmologist.

Swollen Adenoids

This lymph tissue at the back of the throat extends behind the nose. Lymph nodes and tissues become enlarged when an allergy is present, and the effect for you can be a tired or drowsy appearance. Although, not generally a cause for a visit to your ophthalmologist.

Swollen, Red, or Itchy Eyes

If allergens enter your eye, white blood cells may invade and set up defensive measures. This causes your eyes to itch and the eyes to take on a reddish tint. If over-the-counter eye drops do not work, call your Orlando ophthalmologist.

Blurry vision

Any infection that comes between your contacts and your eyes can spread from one surface to the other and harbor bacteria for an extended time. If your vision blurs, remove your contacts and call your doctor. Any blurred vision without contacts that does not self-correct also requires an office visit.

Pink Eye or Conjunctivitis

Some forms of conjunctivitis (an infection of the conjunctiva, or eye and eyelid covering) are highly contagious. Unless you are absolutely sure yours is not contagious,it might be time to call your doctor.

Keep your eyes healthy all year with yearly exams, so your Orlando ophthalmologist can determine how your eyes appear normally, as opposed to how it is altered during an allergic reaction. Call Magruder Laser Vision at 407-843-5665 for an appointment, and read our blog page for information on keeping your eyes healthy all year.

5 Activities That Require Eye Protection

Snowbirds come to Florida’s beautiful beaches to slather their bodies with sunscreen and relax under an umbrella. Sometimes, though, they forget to protect their eyes from the sun’s penetrating rays. Your Orlando ophthalmologist, Doc Brock, has a handful of great ideas on how you can protect your eyes while taking in your favorite activities.

Spectator Sports

Whether you are a NASCAR fan or a die-hard Orlando City Pride aficionado, watching sports can be hard on your eyes, especially if your favorite team plays outdoors. Looking up or being at the top of a stadium can lead to inadvertently looking at the sun. This can become problematic if you spend long stretches of time outside without glasses that protect from the sun’s rays. Wear sunglasses whenever possible, even on cloudy days. Overexposure to the sun can lead to early cataracts, thickening of the cornea, and macular degeneration.

Water Activities

Contacts and glasses have an aversion to all things water. Glasses smear and contacts have the disadvantage of popping out when doused with water. In any water environment, wear goggles with your contacts and carry a specialized cleaning cloth for your glasses.

Participating in Sports

Many sports have specific eyewear for users, whether you have impaired vision or not. Look at the requirements for your favorite sport before you begin. If goggles are required, look into prescription goggles or a possible LASIK procedure.


Weekend warriors dedicate countless hours on their lawns. Lawnmowers, trimmers, and edgers are all notorious for flinging debris. Wear sunglasses or safety glasses when operating these unpredictable lawn tools.

Fully enjoy all your year-round activities with a LASIK treatment from your Orlando ophthalmologist. Call 407-843-5665 to schedule an appointment to determine the best procedure so you can participate in life without the worry of tearing your contacts or losing your glasses.

“Firsts” We are Most Proud of

People don’t commonly remember the runner-up in a contest, the silver medalist, or the second banana in a comedy team. Doc Brock at Magruder Laser Vision strives to set the bar higher well before any other Orlando ophthalmologist, in order to give his patients the best, most cutting-edge technology. Below are highlights from Magruder’s long history of pioneering the field of ophthalmology in Orlando. First Refractive Surgery Center In 1996, Dr. Magruder opened Central Florida’s premier refractive surgery center.

First Autonomous Eye-Tracking Laser

Leading technology across the United States, Doc Brock utilized computer-generated tracking to give his patients more accurate laser procedures.

First Custom Corneal Wavefront-Guided Treatment

in 2001, Dr. Magruder paved his way in Central Florida by choosing to determine eye correction by looking at patient's eyes rather than their prescription lenses for a more accurate result.

First Verisyse Phakic Intraocular Lenses

Since 2005, permanently installed contacts have allowed patients, with vision that is not correctable with LASIK, to view the world with more precision.

First Alcon Wavelight Refractive Suite

The suite of Alcon products, from lasers to computers to monitors, allows fewer errors and more reliable patient outcomes. Magruder’s Wavelight Refractive Suite has been helping patients since 2005.

First Staar Visian Implantable Contact Lens (ICL)  

In 2006, patients in Central Florida had another option for vision correction: the Staar Visian ICLs. Patients with severe myopia now had a viable option to correct their vision.

First Intralase iFS

As technology was updated, Dr. Magruder introduced the Intralase iFS to his patients. Beginning in 2011, many varieties of laser procedures were then performed with the aid of the Intralase iFS.

First LENSAR Cataract Laser

2012 heralded in the LensAR cataract laser for patients with occluded lenses by using augmented reality to judge the density of each individual cataract.

First KAMRA Inlay

In 2016 Central Florida patients with presbyopia or hyperopia had the advantage of KAMRA inlays which focused on near-vision difficulties with a permanent solution not requiring “readers.”

Our “firsts” are only going to be topped as we are more prepared and excited to see where technology takes the Orlando ophthalmologists at Magruder. Call us today at 407-843-5665 for a free LASIK consultation so you, too, can develop your own “firsts.”
