What is a Lazy Eye?

Amblyopia, or lazy eye, is an acquired defect in vision caused by a deficient visual experience early in life.  It is usually found in one eye only but may be affecting both eyes. Amblyopia itself produces no change in the appearance of the eye, but it nearly always develops in association with some other condition, such as a high refractive error or eye turn, which is observed through an eye examination and which is responsible for an inadequate visual experience.

The word amblyopia (derived from Greek roots meaning “blunt sight”) is occasionally still applied to other disorders in which partial loss of vision is congenital or acquired through processes unrelated to visual experience.  The degree of amblyopia is determined by observing how well the patient can read a standardized eye chart with the best visual correction.  

The visual system is sensitive to the effects of abnormal visual experience only during a limited time in infancy and childhood when it is immature and still changing. For humans, this period extends roughly from birth through the end of the first ten years of life. Vulnerability is greatest during the first few months of life and decreases gradually thereafter, with apparently considerable variation from person to person in the degree of sensitivity at a particular age.

Abnormal early visual experience can affect monocular vision through either or both of two amblyopia causing mechanisms: In the first, lack of exposure to the sharply focused images necessary for normal development disturbs and limits the development of normal vision.

In the second, marked disparity in the quality or directionality of inputs from the two eyes prevents binocular fusion and results in abnormal competitive binocular interaction, which leads to active interference with, or exclusion of, one eye’s input to higher visual centers that persists during single eye viewing. This is caused by a persistent eye turn, also called strabismus. This disturbs development of normal vision in the brain’s visual center.   

Either mechanism can contribute to one eye or two eye amblyopia: The two eyes may be affected simultaneously by the first mechanism or sequentially by the second.

Refractive amblyopia may be corrected over time by wearing glasses or contact lenses with the correct prescription full time.  The earlier a patient wears the correct prescription, the better the outcome of achieving normal vision be.  In strabismic amblyopia with large eye turns, surgery may be needed to fully correct the eye and restore normal vision.  Patching the better eye will often encourage the patient to use the amblyopic eye and stimulate the visual system to develop correctly, resulting in improved vision.      

How Did Versant Health Get its Name?

This is excerpted from Lippincott.com graphic designers website. Unfortunately, none of this is true.

Versant Health

A new vision for the future of eye healthAwardsGraphis Design Annual, 2020: Honorable Mention, Branding
GOOD Design Award, 2019

Did you know that a single eye exam can detect over 35 different diseases? Vision care is an essential — though often uncredited — part of total health. But there’s a newly formed company that’s rethinking the landscape. The Superior Vision and Davis Vision combination introduced a new leader in managed vision benefits — one that brings together distinct legacies of premium service and value.

Lippincott was brought in to create a new, purpose-led brand platform and bring together the equities of Superior Vision and Davis Vision in a powerful way. The platform commits to keeping customers at the center of all they do, while looking ahead to the future. We then brought these commitments to life through design principles that guide the expression and experience of the brand.

We coined a name — Versant Health — that captures the organization’s dedication to an optimal health experience. “Versant” reflects the experience and conversational approach it brings to every interaction. It’s distinctive, but intuitive. The active “–ant” ending adds dynamism and flexibility. And the addition of “Health” grounds the organization in its industry while broadening the scope of traditional vision care.

We then created an identity system to help establish Versant Health and unify Superior Vision and David Vision as its market brands. We designed a powerful symbol to represent the organization’s shared vision and used it strategically to link all three brands. We further created a visual and verbal design system based on a unique character that brought together hard-hitting science and emotional benefits. The leading messages are bold and evocative. Ideas connect to the next idea. And with a set of unique verbal gestures, the Versant Health voice can remain true while flexing appropriately for different audiences and contexts.

Of course, a transformative brand platform, a meaningful name, and a dynamic visual and verbal design system don’t mean much if they aren’t put into action effectively. Since the launch, we’ve continued to work closely with Versant Health’s team to fully operationalize the unified approach across a broad range of brand interactions. It’s through this process that Versant Health is proving itself as a new leader, redefining the impact of vision in overall health.

Why Do My Child’s Eyes Turn In? Especially When Reading?

Children’s eyes, and many adult’s eyes, often turn in when reading because they are farsighted or hyperopic.

When eyes are hyperopic, focusing on near objects, also known as accommodation, causes the eyes to converge or turn in.  Hyperopes who don’t wear their glasses must focus their eyes, or accommodate, to a large degree in order to see clearly at near. 

These focusing attempts stimulate the accommodative reflex which in turn causes the eyes to converge.  When the convergence of the eyes is greater than the amount the eyes can focus, the eyes then will turn in even more making the eyes appear crossed.  This is called accommodative esotropia.  

This is easily corrected by wearing and eyeglass or contact lens prescription with plus lenses of suitable strength.  With the patient wearing the correct prescription, the eyes will not be turning in anymore.
