The results suggest that nearsighted children as young as 8 years old reap social benefits from wearing contact lenses instead of glasses, researchers say.
The research indicated that children’s global self-worth was not significantly affected by whether they wore contact lenses or eyeglasses. Similarly, the type of vision correction had no effect on how they felt they performed in school or how they perceived their own behavior.
“The effects really seem to be in areas that we would think made sense – how they feel about their appearance, athletic abilities and what their friends think of them,” said Jeffrey Walline, assistant professor of optometry at Ohio State University and lead author of the study.
The research is published in the March issue of the journal Optometry and Vision Science.
The study was conducted at five clinical centers in the United States that enrolled a total of 484 nearsighted children between the ages of 8 and 11. Of those, 237 were randomly assigned to wear eyeglasses and the other 247 were randomly assigned disposable soft contact lenses for the three-year duration of the trial.
Before assigning corrective lenses for the study, the researchers surveyed the participants to determine whether they had low or high satisfaction with the eyeglasses they had been wearing before the study began. This was done to determine whether previous unhappiness with eyeglasses might influence how the children with contact lenses perceived themselves.
“We thought kids who hated wearing glasses would have a lot greater benefit from contact lens wear than kids who thought glasses were perfectly fine,” Walline said. “Overall, across the scale, it didn’t seem to have much of an effect. But what that tells us is that, regardless of what kids think of their glasses, they seem to benefit from contact lens wear in these three specific areas.”
Though the participating children’s global self worth scores increased across the board over the course of the study, there was no significant difference in overall self-worth between the two treatment groups.
However, on average, contact lens wearers reported better perceptions about their own appearance than did kids wearing eyeglasses.
“The largest difference between the treatment groups was for physical appearance, regardless of whether they initially liked wearing glasses,” Walline said. “This indicates that children’s physical appearance self-perception is likely to improve with contact lens wear, even if they don’t mind wearing glasses.”
While children’s perceptions about their ability to play sports varied over the three years, over the duration of the study, in general, the kids with contact lenses felt better about their athletic competitiveness than did kids wearing eyeglasses.
The children with contact lenses also felt they were more accepted by their friends than did those wearing eyeglasses. But over the course of the trial, both treatment groups experienced an overall increase in their social acceptance scores.
One area that was affected by how kids previously felt about eyeglasses was scholastic competence. Children who had disliked their glasses and were then assigned contact lenses for the study ended up feeling more confident about their school performance.
Walline said the study suggests that even young children should be given the option to select contact lenses over glasses.
“Kids, in consultation with parents, should be able to choose what kind of vision correction they want,” he said. “Age should not be the determining factor for whether a child receives contact lenses or eyeglasses. Look at a child’s motivation, abilities, maturity, hygiene, eye size – lots of those factors – but don’t look at age. There are 6-year-olds who can wear contact lenses on their own and there are 25-year-olds who can’t.”
This work was supported by Johnson & Johnson Vision Care Inc. and The Vision Care Institute, a Johnson & Johnson company. The company supplied the contact lenses used in the study.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
