Refractive Error & Amblyopia
Early Eye Care Can Protect Vision Development
Understanding Refractive Errors
Refractive errors occur when the eye cannot properly focus light on the retina, causing blurred vision. They are common vision problems that can be easily corrected with glasses, contact lenses, or surgery.
Types of Refractive Errors
Myopia (Nearsightedness)
Description:
Myopia is a condition where nearby objects appear clear, but distant objects look blurry. It commonly develops during childhood and is often caused by the eye being slightly longer than normal.
Causes:
The eyeball is too long, or the cornea is too curved, causing light to focus in front of the retina.
Hyperopia (Farsightedness)
Description:
Hyperopia is a condition where distant objects may appear clearer than nearby objects. It can cause eye strain, headaches, and difficulty focusing on close tasks like reading.
Causes:
The eyeball is too short, or the cornea is too flat, causing light to focus behind the retina.
Astigmatism
Description:
Astigmatism occurs when the cornea or lens has an irregular shape, causing blurred or distorted vision at all distances. It may also lead to eye strain and headaches.
Causes:
An irregularly shaped cornea or lens causes light to focus on multiple points on the retina.
Presbyopia
Description:
Presbyopia is an age-related condition that usually develops after the age of 40, making it difficult to focus on nearby objects. Many people notice difficulty reading small text or using mobile phones closely.
Causes:
The lens of the eye becomes less flexible with age.
Frequency of Eye Examinations
- Children
First Exam: Between 6 months to 1 year.
Preschool: At 3 to 5 years old.
School Age: Before first grade and every two years thereafter, or annually if the child wears glasses or contacts.
- Adults
Ages 18-60: Every two years.
Ages 61 and older: Annually.
Myths and Facts about Spectacles
Myth: Using spectacles is bad for children.
Fact: Spectacles are safe and necessary for children with refractive errors to see clearly and perform well in school.
Myth: Using spectacles will keep increasing eye power.
Fact: Properly prescribed glasses do not worsen refractive errors. Changes in prescription are often due to natural progression of the condition.
Guidance on Use of TV and Mobile Phones for Children
Moderation: Limit screen time to reduce eye strain and encourage breaks every 20 minutes.
Distance: Ensure screens are at least an arm’s length away.
Lighting: Use screens in well-lit areas to reduce strain.
Activity: Encourage outdoor play to balance screen time.
Adverse Effects of Excessive Screen Time
Eyes: Can cause digital eye strain, dry eyes, and may contribute to myopia progression.
Brain: Overexposure to screens can impact sleep patterns and cognitive development.
Foods for Eye Health
Leafy Greens: Spinach, kale, and collard greens are rich in lutein and zeaxanthin.
Fish: Salmon, tuna, and other oily fish provide omega-3 fatty acids.
Citrus Fruits: Oranges, lemons, and grapefruits are high in vitamin C.
Nuts and Seeds: Almonds and sunflower seeds offer vitamin E.
Carrots and Sweet Potatoes: High in beta-carotene, a precursor of vitamin A.

What is Amblyopia?
Amblyopia, also known as “lazy eye,” is a vision development disorder where one eye fails to achieve normal visual acuity, even with prescription glasses or contact lenses. It typically develops in early childhood and can lead to permanent vision impairment if not treated promptly.
Causes Of Amblyopia
Patching Treatment
BYNOCS (Binocular Computerized System) is a modern treatment for amblyopia that uses computer-based exercises to stimulate the visual system and improve binocular vision.
Patching Treatment
BYNOCS employs a series of interactive, game-like exercises that are designed to be engaging and fun for children. These exercises stimulate both eyes simultaneously, encouraging binocular vision and coordination.
Patching Treatment
Engagement More enjoyable for children, leading to better compliance.
Binocular Vision Enhances binocular function and depth perception, unlike patching which focuses solely on the weaker eye
Efficiency Can be more effective in improving overall visual function in a shorter time frame.
Patching Treatment
Patching treatment involves covering the stronger eye with a patch to force the use of the weaker eye. This stimulates visual development in the amblyopic eye and helps improve its visual acuity.
Contraindications for BYNOCS Treatment
Severe Strabismus If the eyes are highly misaligned, BYNOCS may not be effective.
Untreated Eye Diseases Conditions such as active infections or severe cataracts need to be addressed first.
Very Young Children It may be challenging for very young children to engage with computer-based exercises.
Compliance Issues Requires the child’s willingness and ability to participate in the exercises regularly.
