Choosing Glasses and Sunglasses
When evaluating children’s lenses it is important that their lenses be thinner, so that the glasses are lightweight and comfortable. Their lenses should also be made from shatter-proof materials – consider polycarbonate lenses – to protect their eyes if the glasses are impacted by a flying object or if the glasses are damaged as the result of a fall. In addition, transition lenses – which change from light to dark when exposed to sunlight – should also be considered for children as it eliminates them needing to have two pairs of glasses.
One of the most common reasons for children to wear glasses is to correct a refractive error. Single-vision lenses are best-suited to this purpose, and as a result, are what is primarily prescribed for them.
Pros: Wearers can see clearly at a distance or at close range, depending on prescription.
Cons: Wearers may need more than one pair of glasses, such as sunglasses or sports protection glasses, for other activities.
If children see clearly at a distance, but objects look blurry at close range, or vice versa, single-vision lenses can help. These lenses are designed to correct either nearsightedness or farsightedness, but not both at the same time. The lenses’ power is the same throughout and determined by children’s eye care providers during their eye exam.
