Dry Eye can have a major impact on your quality of life. You may find your eyes get tired faster or you have difficulty reading. Not to mention the discomfort of a burning sensation or blurry vision. Let’s take a look at dry eye treatments – from simple self-care to innovative prescriptions and therapies – to help you see clearly and comfortably.
 

What is Dry Eye?

Understanding dry eye will help you determine the best treatment option. Dry eye occurs when a person doesn't have enough quality tears to lubricate and nourish the eye. Tears reduce eye infections, wash away foreign matter, and keep the eye’s surface smooth and clear. People with dry eyes either do not produce enough tears or their tears are of poor quality. It’s a common and often chronic problem, especially in older adults.
 

Preventive Self-Care

Before we delve into more serious dry eye treatment options, here are a few simple self-care options that can manage minor cases of dry eye.

• Blink regularly when reading or staring at a computer screen for a long time.

• Make sure there’s adequate humidity in the air at work and at home.

• Wear sunglasses outside to reduce sun and wind exposure. Wrap-around glasses are best.

• Take supplements with essential fatty acids, as these may decrease dry eye symptoms.

• Drink 8 to 10 glasses of water each day to avoid dehydration.

• Find out if any of your prescriptions have dry eye as a side effect, and if so, see if you can take an alternative.
   

Artificial Tears

For mild cases of dry eyes, the best option is over-the-counter eye drops. Here are a few tips for selecting the right one:

• Low viscosity – These artificial tears are watery. They often provide quick relief with little or no blurring of your vision, but their effect can be brief, and sometimes you must use these drops frequently to get adequate relief.

• High viscosity – These are more gel-like and provide longer-lasting lubrication. However, these drops can cause significant blurring of your vision for several minutes. For this reason, high-viscosity artificial tears are recommended at bedtime.
   

Prescription Dry Eye Treatments

There are several prescriptions that treat dry eye differently. Your eye doctor can advise the best option for your situation.

• Contact Lenses – There are specialty contact lenses that deliver moisture to the surface of the eye. They’re called scleral lenses or bandage lenses.

• Antibiotics– If your eyelids are inflamed, this can prevent oil glands from secreting oil into your tears. Your doctor may recommend antibiotics to reduce inflammation.

• Tear-stimulating drugs – Available as pills, gel, or eye drops, cholinergic (pilocarpine, cevimeline), these help to increase tear production.

What Is Myopia?

Myopia (or nearsightedness) is so common that nearly 50% of North Americans will have myopia by 2030. Myopia happens when the eye grows too fast, too long, and gets weaker. You may know it as blurry vision far away. At our practice, we specialize in pediatric eye care and treat myopia seriously.

Myopia can develop as young as age 3, and it often gets worse as children grow. Parents may not see signs that their child has myopia, such as squinting or having to sit up close to the television or computer screen to see clearly. Children often don’t realize their vision is blurry.

The heavy use of digital devices is not going away and certainly is not helping things. It is important to have your child take breaks that are at least 5 minutes long, at least once an hour. Children should also spend at least 90 minutes outside a day.

The younger your child, the faster their myopia tends to progress. Early and regular pediatric eye exams are essential for detecting myopia as soon as possible. Treating it early can help slow its progression and reduce the risk of serious eye health issues later in life.
 

Myopia Can Affect More Than Just Your Eyes

Myopia can affect your child’s ability to perform well in school, sports, performing arts, and other activities that require clear vision. Controlling myopia progression will free them up to be at their best.

If you believe that your child may have myopia, contact our office to schedule a pediatric eye exam - this is the best first step to take.

Over the years, contact lenses have evolved. A new product called MiSight is giving children a new and improved option. MiSight lenses effectively treat myopia, otherwise known as nearsightedness.
 

Myopia

Myopia is the medical term used for nearsightedness. Of all correctable visual impairments, myopia ranks number one. With this condition, the eye grows too long from the front to the back. As a result, images don’t focus on the retina. Instead, they focus at the front of it. With this refractive error, individuals can see things up close without any problem but everything at a distance appears blurry. Over time, myopia in children typically worsens. This refractive error puts them at risk of developing other problems. For example, they’re more prone to having premature cataracts and detached retinas as an adult.

To treat this condition, most opt for prescription eyeglasses or contacts. Although MiSight Lenses work similarly to conventional lenses, they’re unique.
 

Benefits of MiSight Lenses

These contacts slow the progression of myopia in children between the ages of eight and 12. Even more exciting, they slow the progression by as much as 59%. For instance, if an ophthalmologist or optometrist diagnoses a child with nearsightedness and predicts a diopter of -8.00, MiSight contact lenses can reduce that to about -3.50.

As the only contact lens on the market capable of doing this, the Food and Drug Administration (FDA) fully approved them in 2019.

Another benefit of wearing MiSight contacts over traditional lenses is their soft lens. Especially for younger wearers, they provide optimal comfort.

Also, an individual only wears them once before discarding them. It’s important to note that these contacts aren’t made for overnight wear. For that reason, users need to remove them from the eyes and discard them at the end of each day.

As our bodies age, it is normal to notice that there are decreases in our ability to complete certain functions that may have been natural for us in our youth. Just like our physical strength, the strength of your eyes can also weaken over time.

Several different factors influence how each of us will experience aging. Your genetics can play a pivotal role. Understanding your family history and making sure to communicate this with your health professional can be a great way to monitor changes and spot early signs and symptoms. Exposure to certain chemicals or environments or specific trauma to our eyes can also have an impact on how our eyes age. While the eyes can often recover from traumatic injury or exposure, they may still have a detrimental effect on your vision as you age.

Knowing what age you start to have an increased risk of certain diseases or eye conditions can help you to be prepared when you meet with your optometrist. Here are some of the most common ailments that people experience when they age.
 

Presbyopia

Once you are over 40 years old you may experience a loss in vision at close range. Presbyopia is a normal condition that occurs due to the hardening of the lens in your eye. In the early stages, you can often compensate for small changes to your vision, but as the condition progresses, you will likely need a corrective lens, or choose a surgical procedure. such as Lasik, corneal inlays, refractive lens exchange, and conductive keratoplasty.
 

Cataracts

Cataracts are technically a disease of the eye. However, they are so frequently seen in patients as they age, that they are classified as a normal part of aging. While almost half of the population over 65 have cataracts, that number increases even more by age 70. While it can be frightening to begin losing your vision, cataract surgery is extremely successful and can restore up to 100% of the lost vision. If you notice even small changes to your vision, it is smart to talk to your doctor. Cataract surgery is best performed when the cataracts are small and can be more easily removed.
 

Macular Degeneration

This disease is the leading cause of blindness in senior citizens in the United States.
 

Glaucoma

The risk of developing glaucoma generally begins when you are in your 40’s with a near one percent chance and increases throughout the decades with a twelve percent by the time you are in your 80’s.
 

Diabetic Retinopathy

Individuals who have diabetes may be affected by diabetic retinopathy. This disease occurs when blood sugar levels are elevated for an extended period that causes damage to the eye. This damage may lead to permanent vision loss. Americans with diabetes over the age of 40 are at an increased risk, with about 40 percent of people with diabetes over this age displaying some degree of diabetic retinopathy.

Routine eye exams are an important aspect of maintaining one's overall health. As with an annual physical or dental exam, it is extremely important to have your eyes examined regularly. Regardless of how great your eyesight is, scheduling regular eye exams is a great way to stay on top of your overall health.

Adults should have an eye exam every 1-2 years, depending on any existing vision problems, eye conditions or being diagnosed with significant risk factors, such as diabetes, high blood pressure, thyroid disease, previous eye injuries or family history. The doctor will recommend a frequency for routine follow-up exams based on the patient’s medical history. For instance, a diabetic patient will need a dilated eye exam every year while contact lens wearers need exams every year in order to look for changes that might affect lens fit and eye health.

Regular eye exams will also ensure that prescriptions for glasses or contact lenses are current as well as offer an opportunity to check for early signs of certain diseases. Adults older than 60 should have an eye exam each year, as age-related eye problems are more common.

It may be important to see a doctor more frequently if one is experiencing any of the following:
 

• Blurry vision or loss of vision.

• Difficulty seeing things near and/or far away and perform basic tasks.

• Flashing light in the eye.

• Eye floaters, or small spots that appear in vision.

Amblyopia, also known as a “lazy eye”, is described as a reduced vision in one eye compared to the other. There are some rare forms of amblyopia that involve both eyes. Amblyopia is the most common cause of partial or total blindness in one eye in children.

The term lazy eye is misleading because the eye is not actually lazy. In fact, it is a developmental problem in the nerve connecting the eye to the brain, affecting the brain’s ability to use both eyes together. It is not a problem in the eye itself, but in the brain which actively ignores the visual input from the misaligned eye, leading to amblyopia in that eye.

In addition to poor visual acuity, people with amblyopia are more prone to having difficulties with depth perception, eye movements related to reading, and visual decision making while driving.
 

What Are The Causes of Amblyopia?

Amblyopia develops in childhood due to:

• Significant differences in the prescription (refractive) status between the two eyes due to nearsightedness, farsightedness or astigmatism;

• Constantly misaligned eyes or crossed eyes (strabismus);

• An obstruction of vision in early childhood i.e. cataract, ptosis (droopy eyelid)
   

It is important to note that, because amblyopia is typically a problem of infant vision development, symptoms of the condition can be difficult to detect. Symptoms may include noticeably favoring one eye over the other, an eye turn (either upward-downward outward or inward) or a tendency to bump into objects on one side.

The best way to identify children who are at risk for or already have amblyopia is by performing comprehensive eye examinations.
 

How Is Amblyopia Treated?

Amblyopia can be treatable at any age, although the earlier the problem is found and treated, the more successful the outcomes tend to be.

Both optometrists and ophthalmologists treat many common types of ocular disease. However, for the best outcome, it’s important to see an eye doctor regularly. They can identify any issues before they become serious problems.

Fortunately, they can treat all of the diseases mentioned below, and in some cases, you can do certain things to prevent them from developing. Look at the most recent statistics, and you’ll see why good eye health care matters.

Currently, more than 4.2 million people in the U.S. alone over the age of 40 are partially blind or have poor visual acuity. Although a lot of things cause these problems, the ocular diseases listed below are the most common.
 

Macular Degeneration

This is commonly referred to as “age-related macular degeneration” because it affects seniors. Not only does it cause blurriness and distortion but left untreated, individuals lose their central vision. In other words, they are unable to see anything through the center portion of the eye.

Two types of this ocular disease exist. First, wet macular degeneration means that abnormal blood vessels that are located behind the retina grow under the macular. Along with leaking blood and fluid, this leads to scarring and, sometimes, permanent damage. Second, dry macular degeneration progresses slowly as part of the natural aging process. Typically, it affects both eyes at some point.
 

Cataracts

Roughly 20 million people in the U.S. over the age of 40 have cataracts in either one or both eyes. While they can develop in children, teens, and young adults, cataracts are most often associated with age. With this, a film covers the eye, which, in turn, makes everything appear blurry.

Of all the different kinds of ocular diseases that lead to blindness worldwide, cataracts rank number two. Fortunately, an eye doctor can remove the damaged lens, followed by implanting an artificial one. After recovery, patients see amazingly well.

Regular eye exams are important for children since their eyes can change significantly in as little as a year as the muscles and tissue develop. Good eyesight is critical for a child’s life and achievements since success in school is closely tied to eye health. School demands intense visual involvement, including reading, writing, using computers, and blackboard/smartboard work. Even physical activities and sports require strong vision. If their eyes aren’t up to the task, a child may feel tired, have trouble concentrating, have problems in school or have difficulty playing their favorite games which may affect their overall quality of life.
 

When to Perform a Pediatric Eye Exam?

According to research, a child should have an initial screening between 6 and 12 months of age. After that, routine eye health and vision screenings throughout childhood should be performed annually in order to help detect any abnormalities as the eyes develop. 

For a newborn, an optometrist should examine the baby’s eyes and perform a test called “red reflex test” which is a basic indicator that the eyes are normal. In a case that the baby is premature or at high risk for medical problems for other reasons, has signs of abnormalities, or has a family history of serious vision disorders in childhood, the optometrist should perform a comprehensive exam.

A second eye health examination should be done to infants between six months and the first birthday. This examination includes tests of pupil responses to evaluate whether the pupil opens and closes properly in the presence or absence of light, a fixate and follow test to determine whether the baby can fixate on an object such as a light and follow it as it moves, and a preferential looking test which uses cards that are blank on one side with stripes on the other side to attract the gaze of an infant to the stripes and thus vision capabilities can be assessed. Infants should be able to perform this task well by the time they are 3 months old.

For a Preschooler, between the ages of 3 and 3½, a child’s visual acuity and eye alignment should be assessed. If the child is diagnosed with misaligned eyes (strabismus), "lazy eye” (amblyopia), refractive errors (astigmatism, myopia, hyperopia) or any other focusing problems, it’s important to begin treatment as soon as possible to ensure successful vision correction and life-long benefits.

At School age or upon entering school, the child’s eyes should be screened for visual acuity and alignment. In this age group, nearsightedness (myopia) is the most common refractive error and can be corrected with eyeglasses.

Vision therapy is a treatment plan that is intended to develop and improve a patient’s visual skills and abilities, with the goal of making their day-to-day life easier. You may also hear Vision Therapy referred to as VT. Although most commonly associated with children, whose visual skills are still naturally developing, adults can also benefit from vision therapy.

Any patient who does not have the necessary visual skills could find themselves suffering from a range of unpleasant symptoms, including headaches, eye fatigue, stiff neck, and double vision. Fortunately, vision therapy is a simple, painless technique to help patients to enhance their visual skills and overcome any issues that they may have been experiencing.
 

Skills that can be developed and improved through vision therapy

Vision therapy has been shown to be an effective way of developing and improving the following visual skills, all of which are important for day-to-day life. 

• Tracking: this refers to the ability to follow a moving object smoothly and accurately with both eyes – such as moving traffic or a ball coming towards you.

• Depth perception: this is the ability to judge relative distances of objects and move accurately in a 3D space – for example, being able to walk down a flight of stairs.

• Peripheral vision: this refers to the edges of your vision and your ability to assess what’s happening in your peripheral vision while paying attention to something directly in front of you.

• Acuity at different distances: this is the ability to see clearly enough to identify and understand objects at both near and far distances. 

• Fixation: enabling patients to quickly and accurately look at, identify and understand stationery objects one after the other, for example, reading word to word. 

• Binocular vision: the ability for both eyes to work together in perfect synchronization.

• Shifting focus: patients with this skill can look quickly at different distances without momentary blur. 

• Visualization: a valuable visual skill that enables patients to form and retain images in their head. 

You have almost certainly heard of diabetes, which is one of the most common chronic health conditions in the United States, with an estimated 100 million adults currently living with diabetes or pre-diabetes. This metabolic disorder occurs when the body is no longer able to regulate its own blood sugar levels and requires intervention to keep them stable. Most people are aware that diabetes can have serious consequences for their health. However, you may be surprised to learn that it can also influence our vision. This is because patients who are diabetic can go on to develop a complication known as diabetic retinopathy. Without prompt treatment, diabetic retinopathy can cause permanent vision loss. It is for this reason that patients who suffer from diabetes are asked to attend regular diabetic-related eye exams.
 

What is diabetic retinopathy?

For us to be able to see clearly, our eyes need to be healthy and functioning perfectly. The most important component of our eyes is the retina. Found at the very back of the eye, the retina is a patch of light-sensitive cells that have the job of converting the light that passes into the eye into messages that are passed up the optic nerve and into our brain. Our brain then receives them and tells us what we can see and how clearly we can see it. 

The retina relies on a continuous supply of blood, which is delivered using a network of tiny blood vessels. Over time, having continuously high blood sugar can damage these blood vessels, causing a leak of blood and other fluids onto the retina. If this happens, scarring may occur, which could compromise the quality of your vision. 
 

Am I at risk of diabetic retinopathy?

Technically, anyone who suffers from diabetes, whether it be Type 1 or Type 2, could be at risk of developing diabetic retinopathy. However, the condition is more likely in certain situations. These include if:

• Your blood sugar levels are uncontrolled or poorly controlled

• You have a long history of diabetes

• You have high blood pressure (hypertension)

• You suffer from high cholesterol 

• You are pregnant
   

Regular diabetic-related eye exams will enable your eye doctor to monitor your condition and ensure that any signs of diabetic retinopathy are detected and acted upon immediately.
