Dry eye is a very common problem that affects women more than men and becomes more prevalent as people get older.

Signs and symptoms can range from mild to severe.  It can present in many ways, with symptoms that can include a foreign body sensation, burning, stinging, redness, blurred vision, and dryness. Tearing is another symptom and occurs because the eye initially becomes irritated from the lack of moisture and then there is a sudden flood of tears in response to the irritation.  Unfortunately, this flood of tears can wash out other important components of the tear film that are necessary for proper eye lubrication.

There are medications that have the potential to worsen the symptoms of dry eye. Here are some of the broad categories and specific medications that have been known to potentially worsen the symptoms:

• Blood Pressure Medications – Beta blockers such as Atenolol (Tenormin), and diuretics such as Hydrochlorothiazide.
• GERD (gastro-esophageal reflux disorder) Medications – There have been reports of an increase in dry eye symptoms by patients on these medications, which include Cimetidine (Tagamet), Rantidine […]
  

In our modern world, people spend hours on end staring at computer screens, smartphones, tablets, e-readers, and books that require their eyes to maintain close focus.

For most people (all except those who are nearsighted and aren’t wearing their glasses), their eyes’ natural focus point is far in the distance. In order to move that focus point from far to near, there is an eye muscle that needs to contract to allow the lens of the eye to change its shape and bring up-close objects into focus. This process is called accommodation.

When we accommodate to view close objects, that eye muscle has to maintain a level of contraction to keep focused on the near object. And that muscle eventually gets tired if we continuously stare at the near object. When it does, it may start to relax a bit and that can cause vision to intermittently blur because the lens shape changes back to its distance focal point and the near object becomes less clear.

Continuing to push the eyes to focus on near objects once the focus […]

If you are seeing the 3 F's, you might have a retinal tear or detachment and you should have an eye exam quickly.

The 3 F's are:

• Flashes – flashing lights.
• Floaters – dozens of dark spots that persist in the center of your vision.
• Field cut – a curtain or shadow that usually starts in peripheral vision that may move to involve the center of vision.

The retina is the nerve tissue that lines the inside back wall of the eye and if there is a break in the retina, fluid can track underneath the retina and separate it from the eye wall. Depending on the location and degree of retinal detachment, there can be very serious vision loss.

If you have a new onset of any of the three symptoms above, you need to get in for an appointment fairly quickly (very quickly if there are two or more symptoms).

If you have just new flashes or new floaters you should be seen in the next few days. If you have both new flashes and new floaters or […]

When soft contact lenses first came on the scene, the ocular community went wild.

People no longer had to put up with the initial discomfort of hard lenses, and a more frequent replacement schedule surely meant better overall health for the eye, right?

In many cases this was so. The first soft lenses were made of a material called HEMA, a plastic-like polymer that made the lenses very soft and comfortable. The downside to this material was that it didn’t allow very much oxygen to the cornea (significantly less than the hard lenses), which bred a different line of health risks to the eye.

As contact lens companies tried to deal with these new issues, they started to create frequent-replacement lenses made from SiHy, or silicone hydrogel. The oxygen transmission problem was solved, but an interesting new phenomenon occurred.

Because these were supposed to be the “healthiest” lenses ever created, many people started to overwear their lenses, which led to inflamed, red, itchy eyes; corneal ulcers; and hypoxia (lack of oxygen) from sleeping in lenses at night. A new solution […]

What do amblyopia, strabismus, and convergence insufficiency all have in common? These are all serious and relatively common eye conditions that children can have.

Did you know that 80% of learning comes through vision? The proverb that states ”A picture is worth a thousand words” is true!  If a child has a hard time seeing, it stand to reason that she will have a hard time learning.

Let’s explore amblyopia, or “lazy eye.” It affects 3-5% of the population, enough that the federal government funded children’s yearly eye exams through the Accountable Care Act or ObamaCare health initiative. Amblyopia occurs when the anatomical structure of the eye is normal but the “brain-eye connection” is malfunctioning. In other words, it is like plugging your computer into the outlet but the power cord is faulty.

Amblyopia needs to be caught early in life–in fact if it is not caught and treated early (before age 8) it can lead to permanent vision impairment. Correction with glasses or contacts and patching the good eye are ways it is treated. Most eye doctors agree […]

Living an overall healthy life is good for your eyes. Healthy vision starts with healthy eating and exercise habits.

There's more to complete eye health than just carrots. Are you eating food that promotes the best vision possible? Learn what foods boost your eye well-being and help protect against diseases. Here are important nutrients to look for when selecting your foods.

• Beta carotene or Vitamin A (helps the retina function smoothly): carrots and apricots
• Vitamin C (reduce risk of macular degeneration and cataracts): citrus and blueberries
• Vitamin E (hinders progression of cataracts and AMD): almonds and sunflower seeds
• Riboflavin (helps your eyes adapt in changes in light): broccoli and bell peppers
• Lutein (antioxidant to maintain health while aging): spinach and avacado
• Zinc (transfers vitamin A to the retina for eye-protective melanin productions and helps with night vision): beans and soy beans
• DHA (helps prevent Dry Eye): Fatty fish like salmon and tuna

Keep in mind, cooked food devalues the precious live enzymes, so some of these foods are best eaten raw.
