Common signs that a child has a vision problem that requires corrective eyewear include:
Consistently sitting too close to the TV or holding a book too close. Losing his or her place while reading. Using a finger to follow along while reading. Squinting, tilting the head to see better. Frequent eye rubbing. Sensitivity to light. Excessive tearing. Closing one eye to read, watch TV or see better. Avoiding activities that require near vision, such as reading or homework, or distance vision, such as participating in sports or other recreational activities. Complaining of headaches or tired eyes. Receiving lower grades in school than usual.
Schedule an appointment with your eye doctor if your child exhibits any of these signs.
Anti-reflective coating, also known as AR coating, helps you to see through your eyeglasses more easily, lets others see your eyes better and eliminates the annoying white glare spots in photos taken with a flash.
Glasses are online are inexpensive for a reason. They are not able to get the correct measurements. Some measurements are taken in person, for good reason. The ocular center is an important measurement taken to provide clarity and the best vision possible.
That is not able to be taken in on line accurately. PD (pupillary distance) is also a crucial measurement, done incorrectly and you will not see as well. Lastly, lenses online are not normally good quality. Anti-reflective lenses are not made the same and can be easily scratched, so a well-made coating is important.
