How do I know if I need a new glasses prescription?

It can be hard to tell when things have changed enough to need a new prescription. This is largely because your eyesight tends to change slowly and gradually, so every day looks pretty similar to the day before. However, a sudden loss of vision can indicate a serious medical condition, so if that occurs, go directly to your local eye doctor and ask for a full eye exam with dilation.

How do I know if my kid needs glasses?

The majority of kids have normal development and see pretty well by age 5. However, if you notice an eye turn (like a crossed or wandering eye) or if your child seems to need to sit close to something, they may have early vision issues, so you should take them to a pediatric optometrist.

How do you know if you qualify for LASIK?

There are a number of criteria a patient must meet to be a good candidate for LASIK, including having an appropriate prescription—typically a myopic/near-sighted Rx at a level of about a -3.00 to -7.00, with mild to moderate astigmatism. You must also have healthy eyes and a stable Rx, and ideally be between the ages 25 and 40.
