Recently, I have a **** over my left eye, I am wearing the eyeglasses with the prescription SPH-5.50 for left eye and SPH-6.00 for right eye now. If the myopic degree of my left eye has been increased? I will have my eyes tested this weekend. Normally, how often should I have my eyes tested? Your reply will be appreciated.

Normally, if you are an *****, you' better have your eyes tested every 2 to 3 years if you do not have any problems with your eyes. When at the age 40, you should have a comprehensive eye exam, with follow-up eye exams every 2 years.
