Local School Screenings
We are actively involved in the State of Texas mandated vision and hearing screenings in the local schools. Is your school or facility interested in screenings at no cost to you?

General Information and FAQs
Operation Kid Sight Screening is a vision-screening program offered by the Spring Branch Bulverde Family Lions Club that works to identify treatable or preventable causes of blindness in preschool children (ages 2 years – 6 years).
Early Screening is Critical
The first few years of a child’s life are critical in the development of normal vision. A child with vision problems often does not realize that the way they see the world is not the way everyone else sees it. Vision abnormalities in a child’s eyes may occur even when the eye appears to look normal. It is estimated that 3–4% of children may have vision loss from undetected amblyopia—what is commonly referred to as “lazy eye.” Amblyopia results when one or both eyes send a blurry image to the brain and the brain does not learn to see clearly. If this and other problems are not detected early, a child’s vision may deteriorate to the point of irreversible blindness. Research indicates that 70–80% of what a child learns is visually acquired and there is evidence to suggest that children with undetected vision disorders are more likely to fail in school.
Screening Locations & Funding
Photo Screening is conducted at schools, pre-schools, churches, and neighborhood childcare centers, because they have both the facilities as well as the proximity to a group of children. If parents or a childcare center are interested in scheduling a photo screening, please contact the Spring Branch Bulverde Family Lions at info@SBBLions.com.
We SBB Lions, using funds we have raised in our community, pay the cost of the photo screening in full. Your support of Lions projects pays for this program as well as many other local Hill Country services in which the SBB Lions Club is involved.
Individuals and corporations may contribute to this program directly via the Lions Foundation of West Comal County. These contributions enable Operation Kid Sight Screening to maintain equipment and cameras, purchase new equipment, meet transportation needs, and further Operation Kid Sight Screening’s public education outreach.
The Lions Foundation of West Comal County is a registered 501(c)(3) charitable organization and donations may be tax deductible in accordance with regulations set forth by the United States Internal Revenue Service.

Photo screening FAQs
Q. What is Photo screening?
Operation Kid Sight Screening uses the PlusOptix screening system. The Lions volunteer takes a digital “camera” measurement of the child’s eyes from a comfortable distance of 3 to 4 feet away. Invisible, infrared light is projected through the pupils onto the retina. Pass/fail criteria for the screening system follow guidelines established by the American Association of Pediatric Ophthalmology.
Depending on the refractive error or “prescription” of the eye, the reflected light forms a specific brightness pattern within the pupil, which the software analyzes to detect astigmatism, myopia (nearsightedness), hyperopia (farsightedness), and anisometropia (imbalance between the two eyes). It also performs a gaze analysis to help detect strabismus (eye misalignment). Perhaps the most amazing thing is that, while the child gazes into the instrument’s lens, all this information can be acquired and accessed in as little as two seconds.
Q. What are the age limits or other qualifications for this screening?
The child must be old enough to fixate (look at a flashing light on the camera). This is typically possible after one year of age. The screening is aimed at children who are pre-verbal and who may not be able to describe to parents, teachers, or doctors clues to the fact that they do not have perfect vision. There are other tests, such as reading an eye chart, that are generally better for children over 5 years of age. Remember that the eyes are fully developed by age 6 and any screening and testing problems found after age 6 may be discovered too late to be corrected as a medical condition.
The photo screener does not detect neurological disorders. Therefore, we do not screen developmentally delayed or challenged children. Nor do we screen children who are under 5 and are wearing glasses, or are already under the care of an eye doctor and thus do not need vision screening.
Q. What does the screening cost to the parents or to the school, church, pre-school, or day care center operator?
The screening is provided as a service project at no charge to the parents, child, or the day care operator. The funds are provided through services and projects of the SBB Lions, as well as generous contributions from both individual and corporate donors.
Q. What happens if a child “fails” the screening?
All parents will receive notification of the results of their child’s screening. Those that “fail,” or are “referred,” are advised that the screening indicates that their child may have a vision disorder and the parent is strongly advised to make an appointment with an optometrist or ophthalmologist.
Q. What conditions does the screening test for?
The vision screening instrument can detect the following conditions that have the potential to cause poor vision in one or both eyes. If any of these conditions are detected, we Lions strongly recommend that parents take the child to see an ophthalmologist or optometrist in your area.
(Crossed or misaligned eyes) A condition in which the eyes do not properly align with each other when looking at an object.
In simple terms, Anisometropia is a difference in one's need for glasses between eyes; if left untreated in developing children's eyes the condition can be cause for future poor vision in one eye. Anisometropia is a just the condition in which the two eyes have unequal refractive power. Each eye can be nearsighted (myopia), farsighted (hyperopia) or a combination of both, which is called antimetropia.
A defect in the eye or in a lens caused by a deviation from spherical curvature, which results in distorted images, as light rays are prevented from meeting at a common focus. It results in unequal focusing of light rays as they enter the eye, causing a blurring of objects.
Farsightedness, or hyperopia, as it is medically termed, is a vision condition in which distant objects can be seen clearly, but close ones do not come into proper focus. Farsightedness occurs if your eyeball is too short or the cornea has too little curvature. Left untreated in youngsters, it can contribute to eye crossing.
(Severe near vision) People with myopia have an eye which bends the light coming into your eye too much, which means that the light comes to a focus point before it reaches the retina. This makes vision blurry and is caused by the eyeball being too long or the cornea (the clear window at the front of the eye) being more steeply curved. High myopia is a severe form of myopia in which the eyeball continues to grow and becomes very long from front to back. It can increase the risk for retinal detachment, early development of cataracts, and glaucoma. Early examinations of children at risk are crucial, for the failure to detect high myopia in young children may lead to further vision loss from amblyopia.
Amblyopia occurs in early childhood. When nerve pathways between the brain and an eye aren't properly stimulated, the brain favors the other eye. Symptoms include a wandering eye, eyes that may not appear to work together, or poor depth perception. Both eyes may be affected. Early treatment is usually quite simple and usually includes eye patches, drops, glasses, or contact lenses.
The term anisocoria refers to pupils that are different sizes at the same time. The pupil is the black area at the center of the iris; the iris is the colored part of the eye. The pupil allows light to enter the retina, the light-sensitive tissue at the back of the eye. Normally, the size of the pupil is the same in each eye, with both eyes dilating or constricting together. The presence of anisocoria can be normal (physiologic), or it can be a sign of an underlying medical condition.
