Vision and Pregnancy

A common question that many women come across during their pregnancy is: can my vision change during pregnancy?

During pregnancy a decrease in tear production can be expected, which leads to dryness in eyes, irritation and discomfort. Hormones can also cause fluid buildup in your eyes, similar to how your feet and ankles swell up. Changes such as hormones, blood circulation, metabolism and fluid retention can each affect your eyes and eyesight during your pregnancy. For example, even if it’s a small change, water retention can cause thickness and curvature of the cornea of your eye to slightly increase. It can still affect how well your contacts or glasses correct your vision. If you wear glasses, although it’s unlikely you’ll need to change your prescription, it can still be possible.

Some vision changes can lead to a more serious problem such as Preeclampsia, which is marked by high blood pressure and signs of damage to another organ. Symptoms can include: light sensitivity, blurry vision or seeing flashing lights. If any of these symptoms occur call your doctor ASAP, or go to the ER.

As mentioned before, many women who experience vision changes, will report that they were minor changes. If any of this happens, here are some tips on what you can do to help:

  • If your eyes get dry, ask your eye doctor to recommend lubricating drops.
  • If you normally use contacts, give your eyes a rest. Consider wearing glasses until after delivery. Or check the label to ensure the drops can be used with the contacts, some contacts contain preservatives that can harm soft lenses. To be more safe, talk to your doctor first to check if the ingredients are safe for pregnant women.
  • Don’t switch to a new prescription. Unless the changes are very pronounced, wait until after delivery when your vision will go back to normal.

Luckily, many of these changes are temporary and will reverse themselves several months after delivery.

Signs Your Child Needs Glasses

When your child is of a very young age, it can be difficult to tell if they are having difficulty with their vision or are simply developing strange habits. It can be especially difficult to tell if your child is having vision difficulty if they have yet to learn how to speak. Because of this, we have gathered some common vision impairment signs.

  1.     Getting too close to objects. This is usually a more common concern for parents. If your child is sitting too close to the T.V. or holding objects close up to their face in order to see, they could be near sighted.
  2.     Are constantly squinting or closing an eye. These are other common signs of vision impairment. If your child is doing this, it can be because they are trying to reduce blurred vision or they are trying to cover the poorer vision. These are signs of amblyopia, strabismus or cataract.
  3.     Tilt their head to see. When children constantly tilt their heads when looking at object, it could be to help reduce double vision. If this is the case, they could have an eye muscle imbalance, also known as strabismus.
  4.     Are constantly rubbing eyes. This can be a sign of tiredness or eye fatigue. If this is constantly occurring, it could be a sign of allergic conjunctivitis.
  5.     Teary eyes. This is common for children whose eyelids don’t completely close when they’re asleep. This can cause dry eyes and vision impairment.

If any of these signs are common or visible in your child, schedule an eye exam to help correct their vision and help them see more clearly!

 

Different Types of Lenses

When you first go to purchase glasses, chances are you don’t really think about the multiple varieties of lenses that are out there nor their technical terms. There are many technical terms for glasses that correct different eye conditions, as well as the ones used for different situations.

Single Vision Lenses:

These are the most common lenses used. They are used to correct nearsightedness, farsightedness and astigmatism.

Bifocal and Trifocal:

These lenses have multiple focal points for close-up and far away vision. Lenses like these usually have a line splitting the focal points.

Progressive Lenses:

Just like the bifocal and trifocal lenses, progressive lenses have multiple focal points (intermediate, close and far away points). Unlike bifocals, however, these do not have outlines that determine the focal points, which makes the transition more natural.

Anti-Reflective (AR):

These lenses are designed to cancel out the reflection off the lens surface. This helps to eliminate eye strain when looking at screens and help with night vision.

Scratch Resistant:

These lenses are exactly that, scratch resistant. This helps decrease the amounts of scratches that may affect the eyes.

Aspheric:

These lenses can be made thinner and flatter than regular lenses in order to use a larger portion of the surface because they have various curvatures.

High-Index Plastic:

These types of lenses are usually made for those who need strong prescription. However, these are lighter and thinner than the old school lenses, which were very thick.

Trivex:

These are special lenses for those who work in industries that require eye protection. They are lightweight, thin and impact-resistant.

Polycarbonate:

For those who play sports, these are the lenses you should be using. Just like the trivex lenses, these are also impact-resistant and can also be used to protect eyes in tough work.

Photochromic:

These lenses are known as the transition lenses that transition from clear to dark. They can be made as either glass or plastic. They help reduce eyestrains while transitioning from indoor lighting to outside light.

What Your Prescription Means

If you are one of the estimated 11 million Americans that has a common vision problem such as nearsightedness, farsightedness or astigmatism, then you probably have a prescription for corrective eyewear such as glasses or contact lenses. Do you understand what your script is for and what it means about your vision?

The common eye disorders mentioned above are known as refractive errors and they occur when the eye doesn’t correctly bend, or refract, light as it enters the eye. Let’s take a look at each of these and what it means about your prescription.

The first step to understanding your eyeglass prescription is knowing what “OD” and OS” mean. They are abbreviations for oculus dexter and oculus sinister, which are Latin terms for right eye and left eye. Your eyeglass prescription also may have a column labeled “OU.” This is the abbreviation for the Latin term oculus uterque, which means “both eyes.”

  • Nearsightedness or myopia is when light enters the cornea and is refracted, or “sent” to a spot in the eye before reaching the retina. For people who are nearsighted, the light waves are sent to the wrong place on the retina. Nearsighted is a condition where objects up close appear clearly, while objects far away appear blurry. The extent or amount that a patient is will be denoted in the number on the prescription. If the number appearing under the heading sphere has a minus sign (–), you are nearsighted.
  • Farsightedness or hyperopia means that the light is refracted to a place beyond the retina. Farsightedness means that items far away are clear, but activities like reading and knitting are difficult, because nearby objects appear fuzzy or unfocused. Some people may not notice any problems with their vision, especially when they are young. If the number appearing under the heading sphere on your prescription has a plus sign, you are farsighted.
  • Astigmatism is another refractive error, distorting objects both near and far, so that everything appears out of focus and skewed.

Choices for Contact Lenses

Italian Architect, Mathematician and Inventor Leonardo daVinci (1452-1519) produced the first known sketches that suggested the optics of the human eye could be altered by placing the cornea directly in contact with water. More than 350 years later those ideas were researched and studied to examine how the production of corrective lenses could conform to the front surface of the eye. In 2016, contact lenses are a common choice for people who would like clear vision without the bother of glasses to tote around all day. Since the inception of contact lenses to the vision field, they have come a long way. Let’s examine the types of contact lenses available and what might be right for you.

According to the American Academy of Ophthalmology there are two general types of contact lenses: hard and soft.

  • Hard Lenses – The hard lenses most commonly used today are rigid, gas-permeable lenses (RGP for short). They are made of plastics and other materials such as silicone or fluoropolymers. Hard lenses hold their shape, yet allow the free flow of oxygen through the lenses to the cornea. RGP lenses may be the best choice when the cornea has enough astigmatism (is shaped like an egg instead of an orange); a soft lens will not provide sharp vision. They may also be preferable when a person has allergies or tends to form protein deposits on his or her contacts.
  • Soft Lenses – Soft lenses are the choice of most contact lens wearers. These lenses are comfortable and come in many versions.

In addition there are sub-types of contact lenses that can be chosen based upon your lifestyle of preference for care. For example there are daily wear lenses, which are removed nightly and are replaced on an individualized schedule, and then there are extended wear lenses, which are worn overnight but are removed at least weekly for thorough cleaning and disinfection. Disposable-wear lenses are more expensive, but convenient. They are removed nightly and replaced on a daily, weekly, biweekly, or monthly basis. Talk to your eye doctor about the style that would be right for your life.

 

Pediatric Vision

Parents are always worrying. Are our children eating healthy foods?  Are they getting enough sleep?  Are they getting a cold? One worry that parents commonly have as their children enter school is about vision. Many times parents begin to wonder if their child is squinting and having a hard time seeing the words in books or sentences on the board right around the time when their child enters preschool or elementary school. According to the Annals of Family Medicine, 5 to 10 percent of preschoolers and 25 percent of school-aged children have vision problems.

Due to this statistic, the American Optometric Association (AOA) suggests that infants should have their first comprehensive eye exam at 6 months of age. Children then should have additional eye exams at age 3, and just before they enter the first grade — at about age 5 or 6. For school-aged children, the AOA recommends an eye exam every two years if no vision correction is required.

Pediatric Vision exams are pretty painless and can help start children off right in school. If a child can not see the board or words in a book, they could potentially have delays in reading and language development. The following items will be checked in a pediatric exam: near vision, distance vision, binocular (two eyes) coordination, eye movement skills, focusing skills, peripheral awareness, and hand-eye coordination. Visual acuity should be tested as soon as the child is old enough to cooperate with an eye exam using an eye chart. Photoscreening is another way to check visual acuity that does not require a young child to cooperate with the test. Either approach to testing will determine whether the child can focus normally at far, middle and near distances.

As parents, you may want to prepare your child, depending upon the age for the exam. For very young children, you may want to play “eye exam” to help them get used to the idea that someone is going to be looking at their eyes. For older children, explain that these tests are not going to hurt but will help the doctor find out more about their eyes and how well they see. Show your child a picture of the machines that may be used by “googling” eye exam. These machines can look like something from out-of-this-world so, it is good to prepare the child in advance. Another method that works is by bringing your child to your eye exams in advance to show them what the experience is like.

Vision and Pregnancy

Pregnancy can be an amazing experience full of new feelings and the excitement of the arrival of a beautiful baby.  Unfortunately, pregnancy can also throw more than its fair share of curve-balls.  Swollen feet and ankles, back pain, mood swings and, of course, the dreaded “morning sickness” are just the start of the potential side effects of pregnancy. Many pregnant women are surprised when their vision changes. The fact is that hormonal and physical changes that accompany pregnancy can affect eyesight. Let’s examine the vision issues that can accompany pregnancy.

  • Blurry Vision – Water retention (common during pregnancy) may cause the thickness and curvature of the cornea of your eye to increase slightly. It’s a small change, but it could affect how well your glasses or contacts correct your vision. It’s also why laser eye surgery isn’t recommended during pregnancy and why it’s not a good time to be fitted for new contact lenses.
  • Dry Eyes – During pregnancy, some women may notice that their eyes are drier than usual. Dry eyes can make wearing contacts irritating and uncomfortable. Using artificial tears to lubricate eyes may ease dryness.
  • Vision Changes due to Preeclampsia – High blood pressure occurs in 5-8% of pregnancies. Vision changes due to this condition can include: a temporary loss of vision, light sensitivity, blurry vision, auras, and the appearance of flashing lights. Preeclampsia can be a serious condition.  If these symptoms are noticed, contact a doctor or head to an emergency room immediately.
  • Gestational Diabetes and Vision – Pregnancy can also bring about changes in existing eye conditions – for better or for worse. If you have diabetes, see an ophthalmologist before you get pregnant and again in early pregnancy to get screened for damage to the blood vessels in your retina. This condition, called diabetic retinopathy, often worsens during pregnancy, so you’ll need more frequent eye exams while you’re pregnant and in the postpartum period. (Source- The Baby  Center)

What are Ocular Migraines?

Headaches come in all sorts of horrible varieties:  tension, stress, sinus, cluster or plain old migraines to name just a few.  But have you heard or experienced an Ocular Migraine?  These are unique types of headaches that can be both alarming as well as disabling.  Let’s look at this rare type of headache and see how it may  impact vision and daily activity.

What exactly is an Ocular Migraine?

About 1 in 200 people (who regularly experience migraines) will experience these rare migraines.  Ocular Migraines cause vision loss or  temporary blindness in one or both eyes usually following a migraine headache.  Experts sometimes call these episodes “retinal,” “ophthalmic,” or “monocular” (meaning one eye) migraines.

Symptoms of an Ocular Migraine:

Many people report seeing flashing lights, dimness of vision, blind spots in the field of sight, or sometimes blindness. In addition, these symptoms are usually accompanied by a migraine headache that lasts about a day or so.  The migraine may impact only one side the head, pulsate or be worse with activity and light.  To add insult to injury, nausea and vomiting may accompany this type of headache.

Causes and Treatment –

Headache specialist are unsure why some people experience these types of migraines while others do not.  It may be related to spasms in the blood vessels in the back of the eye or nerve cells in the retina. It is important to seek immediate advice/treatment from your eye doctor to rule out any other condition that may be causing this eye event.  As far as treatments go, your doctor will probably prescribe medication to ease the pain as well as prevent future occurrences such as drugs used to treat epilepsy or depression.  Please discuss any symptoms involving your migraines with your health care professional and your personal eye doctor.

Astigmatism

There are many eye disorders that adults and children have that are widely understood and discussed. Most of us understand the concept of being nearsighted and farsighted. Astigmatism, however, is probably one of the more confusing and misunderstood eye problems.  Not only is the vision problem commonly mispronounced but its origin and type of problem is widely misconstrued.  Let’s examine the eye problem astigmatism, what it is and how eye doctors treat it.

What is Astigmatism?

Astigmatism is a fairly common refractive error occurring in about 28% of the population. Refractive errors often are the main reason a person seeks the services of an optometrist or ophthalmologist. What a refractive error means is that the person is seeing blurry because optical imperfections are preventing the eye from properly focusing/bending (refracting) light. The primary refractive errors are nearsightedness, farsightedness and astigmatism.

The Cause of Astigmatism –

The eye’s ability to focus/bend light sharply on the retina primarily is based on three eye anatomy features: 1) the overall length of the eye, 2) the curvature of the cornea and 3) the curvature of the lens inside the eye. Astigmatism occurs when he cornea is not perfectly spherical, then the image is refracted or focused irregularly on the retina. A person can be nearsighted or farsighted with or without astigmatism.

Treatment for Astigmatism

An eye specialist can determine the extent of your refraction problem by using a computerized instrument (automated refraction) or with a mechanical instrument called a phoropter. These methods allow the doctor to show you one lens at a time to find the right refraction for your eye.  Your eye doctor will use the results of your refraction to determine your eyeglasses prescription which can mean eyeglasses or contact lenses. If you prefer contact lenses a special fitting can also help find the right prescription for your eye.  There is also refractive surgery that can assist in these types of cases.  Talk to your eye doctor about what is right for your unique eyes.
