🎓 Skills Your Child Will Develop

• 🥦 Nutrition Awareness — Connecting food to body function — understanding that vegetables fuel muscles, water regulates temperature, and protein builds tissue — gives children an intrinsic reason to make healthy food choices.
• 🌡️ Illness Literacy — Learning age-appropriate facts about illness — what symptoms to tell an adult about, how germs spread, and why rest helps recovery — builds the health literacy that enables children to be appropriate self-advocates for their own health.
• 💬 Health Communication — Learning to describe physical sensations accurately — where it hurts, how it feels, when it started — gives children the language to communicate health needs to adults clearly and be understood accurately in medical situations.
• 🧠 Body Awareness — Understanding how the body works — what makes hearts beat faster, why we need sleep, what food does inside us — builds the health literacy that enables informed, health-conscious decisions throughout life.

Amblyopia, or lazy eye, is a particularly common disorder in preschoolers. Your preschooler may not be aware that how they see may not be the way they should see, and so they may never complain. Parents should be alert for the symptoms and signs of lazy eye because, in its most insidious form, it may be undetectable without an eye exam. Left untreated, lazy eye can cause a lifetime of visual problems.

Exploring Amblyopia

The public normally uses the term lazy eye interchangeably to describe any sort of eye turn or reduced vision, whatever the cause. Technically, this usage is incorrect.

This article discusses amblyopia, a medical term for lazy eye. It refers to reduced vision that has a specific neurological cause.

Why Amblyopia Occurs?

Amblyopia occurs when the vision cells in the brain do not properly develop. This is caused by a lack of “normal” visual input to the brain during the “critical years” of vision development, from birth to about 5 years of age.

Causes and Symptoms

What causes this lack of “normal” visual input? One of the following is present in those with amblyopia:

1. A constant eye turn (strabismus) in one eye
   

One eye that constantly turns (, out, up or down), is an obvious symptom of amblyopia that needs immediate attention.

2. An extremely high prescription in both eyes

This will probably manifest in symptoms of blur. Your preschooler may rub their eyes, complain of difficulty seeing, tilt the head to see better, squint frequently, complain of headaches when reading, or move closer to see things.

3. Unequal prescriptions between the two eyes

This is the most dangerous cause of amblyopia because it is not obvious. In many cases, there are seemingly no symptoms because your preschooler will rely on the better seeing eye and vision can appear “perfect” to many parents and teachers. Preschoolers with unequal prescriptions may close one eye frequently. Covering each of your child’s eyes and asking if they notice a difference in vision may be helpful, but this is not a substitute for an eye exam or screening.

A Lifetime of Amblyopia

Amblyopia is the most common cause of vision impairment in childhood.

Left untreated, amblyopia can have lasting effects into adolescence and adulthood, affecting function in school, the workplace and life in general. One of these lasting effects include reduced depth perception which can affect activities like sports, driving and certain occupations. Also,there is an increased risk for blindness because if the better functioning eye is lost, there is no backup.

Tips

1. Your preschooler needs an evaluation, by an optometrist, pediatric ophthalmologist, or pediatrician, usually by 6 months, even if all seems fine.
   
2. Pay close attention to your preschooler’s visual behavior and eye appearance.
   
3. Amblyopia treatment may include glasses, patching, eye drops, vision therapy, eye surgery, or a combination of these things along with close management with an eye care professional. The goal of treatment is to reverse vision loss as much as possible.

Helpful Tips for Parents - Physical activity reduces preschooler illness frequency, severity, and recovery time. Active children miss fewer sick days and recover faster when ill. - Annual well-child visits are essential even when the child appears healthy. Vision, hearing, developmental, and growth screening catch issues that aren't visible to parents. ## Frequently Asked Questions ### When should I keep my preschooler home from school? Standard exclusion criteria: fever above 100.4°F (38°C), vomiting or diarrhea in the past 24 hours, a rash with fever or unknown cause, pink eye (conjunctivitis) that is weeping and contagious, or a child too ill to participate in activities. A child can return: fever-free for 24 hours without fever-reducing medication, diarrhea/vomiting-free for 24 hours, rash identified as non-contagious, pink eye treated for 24 hours with antibiotic. Runny nose, mild cough without fever, and general tiredness are not sufficient reasons to exclude from school.
