children's eye safety month

August is the global Children’s Eye Health and Safety Month – a perfect reminder for you to have your children’s eyes checked.

Give your children the best opportunities to develop the best possible vision they can, which is why regular vision checks are of absolute importance.

All children’s eyes are mostly healthy, but you should have them examined during scheduled pediatric visits which should ideally start from the age of three onwards.

Symptoms of Eye and Vision Problems in Children

You as parents should be aware of all the signs that indicate whether your child has any vision-related problems such as these:

  • Wandering or crossed eyes
  • A family history of childhood vision related problems
  • Lack of interest in reading or looking at distant objects
  • Squinting or turning his/her head unusually while watching television
  • Eyes are constantly watering or tearing
  • The eyelids are swollen or bloodshot
  • The child is blinking more than usual
  • Child is complaining of blurry vision; eyes are itchy or burning
  • Feel dizzy or ill after doing some close-up vision related activity

Protect Your Child’s Eyes

We should all utilize this month to teach our children about the importance of eye safety and also implement it with immediate effect.

You can protect your child’s eyes by:

  • Making it mandatory for your kids to wear protective eyewear while taking part in any sports or recreational events.
  • Allowing them to play with toys that have no sharp or protruding edges or corners.

The Role of Eye Safety in Your Child’s Life

Now that you have done everything that you possibly can to ensure that your child’s eyes are safe. Whether they are budding sportsmen or simply just playing with their friends, there are a lot of injuries that they are exposed to. According to current stats, roughly more than 12 million children suffer from some kind of vision impairment and eye injuries which are often the cause of eye injuries, of which 42,000 sports-related eye injuries.

Take precautions and protect your children’s vision. This August, give the apple of your eye the gift of clear vision. Be a Super Mom and bring your child to InSight Vision Center for a comprehensive eye checkup.

strabismus crossed eyes

What is Strabismus?

Strabismus, also called wall eye, squint, or crossed eyes, is a condition in which the two eyes are not properly aligned and fail to work as a team when looking at an object. According to the American Association for Pediatric Ophthalmology and Strabismus, approximately 4% of the US population has strabismus.

Types of Strabismus

There are many different types of strabismus, but they can be broadly divided as follows:

  • Exotropia
  • This type of strabismus is also called as wall-eyed. In Exotropia, one eye views at the object directly, and the other eye turns outward away from the nose.

  • Esotropia
  • This type of strabismus is also referred to as crossed eyes or cross-eyed. In Esotropia, one eye looks at the object directly, and the other turns inward toward the nose.

  • Hypotropia
  • Hypotropia is a type of strabismus, where one eye looks directly at the object while the other turns vertically downward.

  • Hypertropia
  • Hypertropia is a type of strabismus, where one eye looks directly at the object while the other turns vertically upward.

Causes of Crossed Eyes (Strabismus)

What causes strabismus?
Each eye is made up of six external muscles (known as the extraocular muscles). These muscles control the eye position and its movement. In a normal binocular vision, these muscles of both the eyes must be coordinated perfectly.

Certain anatomical or neurological problems can interfere with the proper functioning of the extraocular muscles, thus causing strabismus. These problems can originate in the nerves or in the muscles itself. They can also occur in the vision centers in the brain that control the binocular vision.

Strabismus can also occur due to eye injuries or general health conditions.

Risk Factors of Strabismus

Family history: People whose parents or siblings have strabismus are at risk of developing it.
Medical conditions: People suffering from conditions such as cerebral palsy and Down syndrome or have had a head injury or a stroke are more likely to develop strabismus.

Refractive error: People who have uncorrected farsightedness or hyperopia may develop strabismus.

Signs and Symptoms of Strabismus

If you have strabismus, your eyes point outward or inward or focus in different directions. Other symptoms may include:

  • Impaired vision
  • Eyes that do not move together
  • Decreased depth perception
  • Unsymmetrical points of reflection in each eye
  • Double vision
  • Squinting with only one eye
  • Eyestrain or headache
  • Tilting the head to one side

Diagnosis of Strabismus:

A doctor of optometry conducts a comprehensive eye exam to diagnose strabismus. The diagnosis may involve the following steps:

  • Patient History:
  • The eye doctor will ask you about the symptoms. The doctor will also take a note of your general health problems, medications, family history, and other environmental factors that could contribute to the symptoms.

  • Eye Health Examination:
  • The ophthalmologist may use various testing procedures to observe the internal and external structures of your eyes to rule out any eye disease that could contribute to strabismus. The testing will help determine how the eyes respond under normal conditions.

  • Visual Acuity:
  • The eye doctor will measure visual acuity to determine how much vision is affected. The doctor may ask you to read letters (placed near and far) on the reading charts. Visual acuity is written as a fraction. A person with a normal vision has a visual acuity as 20/20.

  • Refraction:
  • The ophthalmologist may conduct refraction to find out the lens power needed to correct any refractive error (farsightedness, nearsightedness, or astigmatism). The doctor uses an instrument called a phoropter and places a series of lenses in front of your eyes. How your eyes focus to the light is measured using a handheld lighted instrument called a retinoscope.

  • Alignment and Focusing Test:
  • Your doctor of optometry may assess how well your eyes work together as a team to view an object. This test will help determine the problem that prevents your eyes from focusing effectively.

    Your eye doctor will diagnose whether you have strabismus after evaluating the information obtained from the tests mentioned above. If you have strabismus, the ophthalmologist will discuss the treatment options with you.

    Strabismus Treatment Options

    There are several treatment options for crossed eyes. They include:

  • Eyeglasses or Contact Lenses:
  • For some people, contact lenses and eyeglasses may be the only treatment needed.

  • Prism Lenses:
  • In prism lenses, one is thicker than the other. The prisms reduce the turning of the eye to view an object by altering the light entering it. Prisms can sometimes eliminate eye turning completely.

  • Vision Therapy:
  • Your eye doctor may prescribe a series of visual activities that can improve your eye coordination and eye focusing. These eye exercises reduce the problems with eye focusing, eye movement, and improve the eye-brain connection for effective eye teaming. These eye exercises can also be done at home.

  • Eye Muscle Surgery:
  • The length or position of the eye muscles can be made to appear straight through eye muscle surgery. Usually, vision therapy is prescribed for patients after the surgery to prevent the eyes from becoming misaligned again and to improve eye coordination.

    The doctors at Insight Vision Center are the most experienced ophthalmologists in California that provide the best services and treatment options for strabismus and other eye problems. Get the eye examination done as soon as possible at our eye clinic in Fresno, CA.

    Lazy eye

    Also known as amblyopia, lazy eye is a vision development disorder that causes abnormal visual development in early childhood. It is developed when the eye and the brain are not stimulated properly, and the brain favors one eye over the other. It can also be said that when nerve cells responsible for vision do not develop as they should, it results in a ‘lazy eye’.

    Usually, amblyopia occurs in one eye, but in some cases, it can occur in both the eyes.

    What causes lazy eye?

    Here are the leading causes of a lazy eye:

    Strabismus – A condition where the muscles responsible for the positioning of eyes are imbalanced is known as strabismus. This imbalance makes it difficult to track an object with both eyes together. As a result, the eyes turn out or cross.

    Now to avoid double vision, the brain ignores the visuals received by the misaligned eye. This eventually leads to a lazy eye.

    Stimulus Deprivation – When light doesn’t enter an eye due to some obstruction, it tends to become weaker. It could be due to eye surgery, glaucoma, a scar, cataract, etc.

    Refractive Amblyopia – When eyes have unequal refractive errors despite correct alignment, it can lead to amblyopia. For example, there may be near or farsightedness in just one eye. Or, there may be significant astigmatism in one eye and not the other.

    What are the symptoms of a lazy eye?

    Here are the symptoms you must look for:

    • Blurred Vision – When both the eyes together cannot focus on a single object clearly, the resulting image tends to be blurred.
    • Double Vision – This is caused due to the misalignment of eyes.
    • Miscoordination – Because of a lack of coordination between the eyes, they can’t focus on an object.
    • Eye Turn – It is a common symptom when both the eyes turn in different directions.

    How is the lazy eye diagnosed?

    Your eye doctor will examine both your eyes, checking for a wandering eye, eye health, difference in vision between two eyes, or poor vision. Before conducting the exam, they will use an eye drop to dilate your eyes which may result in a blurred vision for up to several hours.

    In infants, a magnifying device is used for an eye examination. The eye doctor may also assess their ability to follow moving objects and fix their gaze at a stationary object.

    In children above the age of 3, the test is done using pictures and letters.

    Amblyopia Treatment

    1. Glasses, Contact Lenses or Lasik Surgery
      Your doctor may prescribe corrective glasses or contact lenses to help you focus on things clearly. This, sometimes, also helps with double vision.

      In certain cases, your doctor may suggest undergoing Lasik eye surgery which not only eliminates the problem entirely but also stops it from forming again in the future.

    2. Surgery and Eye Care
      Lazy eye surgery is done to improve the turn and alignment of the eye. After the surgery, you will have to wear an eye patch over the dominant eye. This strengthens the weaker eye. The patch develops the part of the brain that controls the vision.
    3. Atropine Drops
      Atropine drops are put in the unaffected eye to blur its vision. They dilate the vision in the good eye so that the weaker eye can work more and better.

    Early treatment of amblyopia is extremely critical because if overlooked, the condition can lead to permanent vision problems. So, for proper visual development in kids, consult your doctor as soon as you notice any symptoms.

    Bad eyesight

    Bad vision can be caused by astigmatism, nearsightedness & farsightedness. These can be corrected with glasses, contact lenses, or some surgeries. These conditions are genetic to a certain extent, but may also be influenced by your environment. Globally, about 80% of vision impairment cases are avoidable (Source: https://www.who.int/news-room/fact-sheets/detail/blindness-and-visual-impairment). But here’s what science has to say.

    Environment over Genetics

    If two people are nearsighted, it’s more likely their children will be nearsighted. However, if a child spends a lot of time reading or working up close, and not much time outside, they may actually need reading glasses. But if kids are brought up in the right environment, they can maintain good eyesight without experiencing headaches and perform well at school and other activities.

    How Can You Treat Bad Eyesight?

    1. Inculcate Good Habits

    There are plenty of good habits you can inculcate in your child to prevent them from struggling with poor eyesight. Most kids these days carry digital devices with them wherever they travel.

    We’ve seen kids with phones and iPads on the trains, outside a movie theatre, and of course at home. You need to limit the amount of time your kids spend on these devices. These gadgets also shouldn’t be easily accessible. And instead, it should act as a reward.

    Kids should also be encouraged to spend more time outdoors rather than simply gaming or sitting in front of a television. Motivate them to play with the neighbor’s kids or find time to play a ball game with them. Make sure they’re active for a major part of the day.

    2. Provide Vitamins for Eyesight

    Providing vitamins for eyesight is another way for you to make sure that you encourage healthy eating habits and an overall improved lifestyle. This includes eating the right foods that give your kids’ eyesight a big boost. But healthy foods don’t necessarily have to be boring.

    Your kids are simply not going to eat an entire bowl of salad. But if you try to include green vegetables in an omlette, sandwich, or pasta, they will consume all the right vitamins. Encourage your kids to also eat citrus fruits, fish, eggs, and nuts. These foods contain plenty of nutrients and help your child maintain a well-balanced diet.

    3. Get an Early Eye Exam

    While good habits and a healthy diet are important to maintain eyesight, it’s also crucial for you to take your kids for an early eye exam. Many kids may suffer from poor eyesight without even realizing it.

    A healthy set of eyes is essential in the growing years. It helps kids understand the world around, familiarizes them with their immediate environment and people. Good eyesight also helps your child concentrate in the classroom without experiencing mild headaches and blurred vision.

    Taking your kids to an eye doctor will help detect any early eye conditions that can be easily corrected with glasses. In the growing years, kids should get a yearly eye exam done to help them succeed in the classroom, in sports, and in other activities.

    Poor vision may be hereditary to an extent but doesn’t affect your kids’ eyesight if a healthy routine is put into place.

    First time contact lenses

    Are you fed up of all the hassles that come with spectacles? Are you keen on trying contact lenses but have a lot of doubts regarding them? For instance – how to wear them correctly? How to clean them? Can they be worn for longer periods of time continually? Will you get dry and irritated eyes with their prolonged use? Such questions are obvious if you are trying on contact lenses for the first time. However, with proper precaution and care, you can enjoy all the benefits of contacts without any hassles.

    The 5 helpful tips listed below are all you need to know in case you are a first-time wearer of contact lenses:

    1. It is extremely important that you clean your contact lenses every time before putting them on. Even your ophthalmologist will stress the importance of sticking to a strict lens care regime. Use a good quality contact lens solution to rinse and clean your lenses. Ensure that the solution is fresh in the lens case. For instance, when you put on your lens in the morning, drain the case, rinse it with fresh solution and leave it upside down to dry. Once it is completely dry, refill it with fresh contact lens solution.
    2. If you are wearing contact lenses for the first time, the very first challenge you will probably face is – how to put the lenses on. First, you need to wash your hands thoroughly. Next, you need to put the lens on your fingertip. It should be placed in a way that the contact should look like a little cup when held up against the light. Then, pull the upper eyelid upwards and bottom eyelid downwards to prevent blinking reaction. Look upwards and place the lens in your eye. Release the eyelids and close the eyes to allow the contact lens to settle. Repeat the same process with the other eye.
    3. Make sure that you keep the contacts hydrated at both times – when in use and when stored in the case. If the contacts turn dry they can irritate your eyes. In case you use lenses for extended periods of time they are more prone to becoming dry. An ideal solution would be to always carry the contact lens solution wherever you go. This will keep you better prepared to hydrate the lenses so they are comfortable to wear and use.
    4. First time wearers may experience problems like irritation or blurry vision due to contact lenses. It might be due to certain reasons such as poor contact lens hygiene, accumulation of debris etc. If such problems persist for a longer period of time even after taking the right precautions, its best to consult your eye doctor immediately.
    5. It is important that you strictly follow your ophthalmologist’s instructions regarding the use and maintenance of your contact lenses. For instance the wearing and replacement schedule, follow-up appointments, solution prescribed for your lens etc.

    The above-listed tips are sure to help first time contact lens wearers get used to and handle their contact lenses appropriately. It is important to go for regular eye check-ups to ensure that you enjoy a healthy and perfect vision especially if you are wearing contact lenses.
