1. HYPEROPIA IN CHILDREN

2. HYPEROPIA(FARSIGHTEDNESS) Hyperopia, also known as farsightedness, is a common refractive error in children where the eye focuses light behind the retina , making it difficult to see close objects clearly.

3. CAUSES Eye length : The eyeball may be too short from front to back, causing light to focus behind the retina. Cornea shape : The cornea (outer layer of the eye) may have too little curvature. Lens shape: The lens inside the eye may have too little refractive power. Heredity : Hyperopia can run in families, meaning children may inherit it from their parents.

4. SIGNS AND SYMPTOMS Blurred vision at close distances : Children may have trouble reading, writing, or seeing objects close up. Eye strain and headaches : Trying to focus on close objects can cause eye strain and headaches. Squinting : Children may squint to try and see more clearly. Rubbing their eyes : Frequent rubbing can be a sign of discomfort or effort to focus. Lack of interest in school or reading: Difficulty seeing clearly can make it hard for children to learn and participate in activities.

5. DIAGNOSTIC EVALUATION Visual Acuity Test: This test uses an eye chart to measure vision clarity at different distances.  Refraction Assessment: This test determines the prescription needed to correct vision by evaluating how light focuses in the eye. Instruments like a phoropter or retinoscope may be used.  Retinoscopy : The doctor shines light into the eye to observe how light reflects off the retina, helping determine the refractive error. 

6. DIAGNOSTIC EVALUATION Autorefractor Test: This test uses technology to automatically measure the eye's refractive error.  Slit-Lamp Exam: If necessary, this exam assesses the structure of the eyes to determine if the hyperopia is due to a structural issue.  Dilated Eye Exam: Eye drops are used to dilate the pupils, allowing the doctor to examine the back of the eye and rule out other conditions. 

7. TREATMENT Eyeglasses : Most cases of hyperopia can be corrected with eyeglasses. Contact lenses : Contact lenses can also be used to correct hyperopia. Surgery: In some cases, surgery like refractive surgery may be an option, though it's generally not recommended for children.
