Why are children more difficult to fit? Because their facial features are very different from those of an adult.
The frames need to take account of the fact that they have little or no bridge on their nose, that they generally have 'chubby' cheeks and a wide head. The frames also need to withstand much more abuse than adult frames.
Eight is too late. "Children under the age of seven with certain eye conditions have a very limited timeframe in which these conditions can be addressed, after which no spectacles, surgery or contact lenses will give them perfect vision in later life," says Helen Carroll.
Weigh fashion against function - scaled-down adult frames are not suitable for young children. An ophthalmologist or optometrist may accurately prescribe the perfect prescription and advise specific treatment for a young child that may all be undone by poorly fitting spectacles.
Time factor - children require more time and creativity on the part of the dispensing optician. Children must always be fitted by a qualified person.
Ask 'why?' - Why is your child wearing glasses? When should they wear them and how? If their eye needs patching, which eye is it?
Visit the practice regularly to have spectacles readjusted and repaired if necessary.
Cost - buying cheap frames is a "false economy".
