how can I check or have an idea of my eye health before visiting a doctor?

Hi Ar,

Welcome to EmpowHER.  There is no way of knowing your eye health with out seeing an eye doctor, such as an Optometrist.  Your doctor will check your close and distance vision.  You'll read from charts of random letters.  Your doctor will also check other aspects of your vision such as your ability to see in 3D, your peripheral vision, your color perception.  He will also test the pressure in your eyes.  Your doctor will closely examine the different parts of your eye.  He might need to dilate your pupil,  with drops.  This will help your doctor get a clear view of the inside of your eye.  This will also, make your vision sensitive to the sun for a few hours after. 

Best,

Daisy
