What Kind of Eyeglass Lenses are Recommended for Children?

Assessing the visual needs of your child with an eye exam is the first step in protecting your child’s vision.  It is equally important to select lenses that will not only make them see well but also protect their eyes.

Polycarbonate or Trivex lenses are the only lens types that have the potential to reduce—not increase—the risk of serious eye injury.   Polycarbonate and Lexan are used in bullet-proof windshields, safety glasses, helicopter canopies and many other hi performance applications.   Other lens types, including glass and regular plastic (CR-39)  will break into pieces upon impact.  Often the impact from an object does less damage to the victim than the broken eyeglass lenses.

Both polycarbonate and Trivex are thin, lightweight and highly impact resistant.   Kids can do crazy things and accidents can happen, therefore polycarbonate and Trivex are not just recommended for sports but should be used to protect their eyes everyday.

Trivex is highly scratch resistant making it the best option for children.  Polycarbonate is much softer and therefore less scratch resistant, however it is slightly less expensive.  Both lens materials naturally block 100% of UV light without any additional coatings.  The optical qualities of Trivex are much better than those of polycarbonate, therefore there is less distortion and reflection from an ophthalmic lens made of Trivex.  Both lens materials are available in Transitions (get darker outside, lighter inside) and accept an antireflective coating, which prevents reflections, making the lenses look transparent.

Encouraging Early Results in Nearsightedness Prevention Study

The first year of the Stabilization of Myopia by Accelerated Reshaping Technique (SMART) Study has produced some encouraging results in a recent announcement.  According to Dr. Robert L. Davis, co principal investigator of the SMART trial,  “The net effect of this contact lens fitting philosophy is to change the cornea shape for the sole purpose of reducing the amount of myopia as measured by change in refraction” .  “The results of the SMART Study so far are very exciting,” said Dr. Davis. “The outcomes of this study may revolutionize how we manage young nearsighted patients from this point forward”.

The SMART Trial involves 300 patients between the ages of 8 and 14.  The goal of the study is to see if having patients where overnight orthokeratology or corneal molding lenses will stop or slow the progression of nearsightedness.  The SMART Trial is the largest of its kind.  Other studies have also shown that preventing nearsightedness with ortho-K contact lenses is possible, such the CANDY Study.  A study from Ohio State Unversity suggested that wearing Ortho-K lenses overnight actually prevented the eye from becoming longer.  The SMART Trial has just completed the first year of the five year study.  We will continue to keep an eye on this potientially ground breaking study.

How Should We Safeguard Our Children’s Eyesight?

Is it too early to think about what we need to do to get our kids ready for school?  One of the most important “school supplies” is your child’s annual eye exam.    Over 80% of what a child learns is through their eyes, therefore it is important for our kids to see their very best.

Kids often don’t complain when they don’t see well and we can not rely on them to tell us when their vision is blurry.  Blurry vision rarely happens quickly, it happens slowly over time and children and adults alike don’t realize what they have lost because it happens so slowly.  On the Total Eye Care website we have more information on the components of a complete eye exam, school screenings and more information on children and vision.  So carve out some time this busy summer and enhance your child’s learning with an eye exam.

Martha Stewart Discusses the Importance of Regular Eye Care

This is a good video where Martha Stewart discusses common topics in eye care including lazy eye, bifocal contact lenses, importance of eye exams for adults and for learning in children.

Another Study Shows Progression of Nearsightedness Slowed With Contact Lenses

Study from Ohio State University Confirms Prior Studies   Myopia Slowed With Contacts

In February, here in The Eye Doc Blog, we reported that The CANDY Study showed that OrthoKeratology contact lenses markedly slowed the progression of nearsightedness in children.  The results of The CANDY study have now been confirmed in the British Journal of Ophthalmology, the new study, Corneal Reshaping and Myopia Progression, showed that children wearing corneal reshaping lenses, also known as ortho-K or orthokeratology lenses significantly reduced the rate of change of the length of the children’s eyes.  The study participants wore the lenses for two years and ranged in refractive error from -0.75 to -4.00.  The study concluded that previous reports of slowed eye growth following corneal refractive therapy were confirmed.

The archive summary of the study is available here.

Orthokeratology Featured on ABC News

I came across this video on orthokeratology .  I believe it is from 2002, however it is still very relevant and the information still applies to how ortho-k is a safe, viable, non-surgical option to vision correction.  Studies have also shown that overnight ortho-k may prevent or slow the progression of nearsightedness in children.

Study Shows Contact Lenses Improve The Self Image of Children

A new study evaluated the self perception of children between ages 8 and 11, finding that the contact lens wearers had a significantly higher sense of self worth than eye glass wearers in the areas of physical appearance, athletic competence, social acceptance and scholastic competence.

As eye doctors we should not only consider the best mode of correction for the patient but also the social and psychological implications on the child.  More information about the Adolescent and Child Health Initiative to Encourage Vision Empowerment (ACHIEVE) Study is  available here.  This is excellent information for any parent considering whether glasses or contacts are right for their child.

Study Finds Nearsightedness Slowed in Children With Contact Lenses

It’s good to see another study indicating that Orthokeratology Contact Lenses prevent the progression of nearsightedness (myopia).  The Controlling Astigmatism & Nearsightedness in Developing Youth Study (CANDY) was based on a relatively small population (28 patients) and it would have been good to see the rate of myopic progression after removing the contact lenses over a greater period of time, however the data was compelling and warrants further study.

As eye doctors we are often asked if we can prevent the progression of nearsightedness in children.   Clinically, we feel that the answer is probably yes, however there are relatively few studies that have investigated this common question.  The CANDY Study backs up what we feel our clinical experience has taught us.  The progression of nearsightedness in CANDY study patients was 0.37D prior to wearing overnight Ortho-K contact lenses.   When the patients discontinued wearing their lenses they found that the patient’s refractive error, on average, had increased by only 0.03D.

An FDA sponsored study of 300 children started in 2007 and is expected to continue for 5 years.  Hopefully, the FDA study will answer more of our questions.  Additional findings from the CANDY Study found that the younger the child the more beneficial was the effect on controlling myopia and the technique was more convenient.   A more comprehensive look at Orthokeratology including a link to the CANDY Study is available on the Total Eye Care website.

Optometrists, School Nurses Partner to Link Healthy Vision and Improved Classroom Learning

The American Optometric Association and the National Association of School Nurses have come to agreement to promote comprehensive vision care for students to improve a students ability to learn in the classroom.  This comes on the heels of a study published in October by Vision Service Plan that showed that most children have not had an eye exam.  School screenings, while helpful and necessary, are unfortunately often confused by parents as an eye exam.  It will be great to see what the two associations do to promote better eye care and learning in children.  Read the entire press release here.

Survey Shows Most Young Children Have Never Had an Eye Exam

Vision Service Plan has answered a question that many of us have long suspected with the release of  a study conducted by VSP Vision Care.  The nationwide study of almost 4000 Americans called the Consumer Eye Care and Eyewear Survey.  Revealed that 76% of the the children under the age of 5 had never had an eye exam.

“While most parents probably assume that vision screenings provided by pediatricians and school nurses are enough, those screenings are nowhere near as exhaustive as the comprehensive eye exams that optometrists and ophthalmologist provide,” said James Short, O.D., chair of VSP Vision Care’s board of directors.

Dr. Short elaborated further “Before children enter school, an eye doctor should examine the eyes for signs of astigmatism, nearsightedness, farsightendnes and also examine the structure of the eye for telltale signs of serious diseases”.

The study goes on to discuss the importance of providing proper sunglasses for children, tips on how to get children to wear sunglasses, prevention of computer vision syndrome in children and how to spot when your child may need an eye exam.
