If a child has astigm of 0.75 and myopia of 0.5 on both eyes , similar reading , does that warrant the use of spectacle ?

Thank you for your question! With a low power such as yours, you would perhaps be prescribed low power reading glasses. It would be best to go to a eyecare professional for you to get your eyes checked, and for your eyecare professional to give you a recommendation based on his/her examination of your eyes.
