How an Eye Exam Will Determine the Right Prescription for Nearsighted or Farsighted Patients
In your life, there are a lot of things that could get put on hold if you do not have the proper eyeglass prescription. It’s important that you consult with an optometrist and have an eye exam conducted to determine what your prescription needs to be. Going with generic glasses could cause headaches or worsen your eyes. The following are some things you can expect when you have your eyes checked.
Whether you are seeing double, have blurry vision or get headaches after having your eyes open for too long, it could mean that you need glasses. At your eye exam, you will undergo some tests that will help the optometrist determine whether you are nearsighted or farsighted. First, the doctor will have you read eye charts. They will be different distances from where you are so that the doctor can notice whether you see better up close or far away.
With a phoropter, the refractive error of your eyes will be checked. Basically, this shows the doctor where the light rays are when they enter the eyes. If they are off by certain degrees, it indicates what type of condition you have. At this time, the doctor will shine lights into the eyes to see how the reflection is. This shows how the retina and the back of the eye match up through this reflection.
After all is said and done, the optometrist will know exactly what prescription you will need for your eyes. Whether you are nearsighted or farsighted, eyeglasses will probably be prescribed. What the lenses of the glasses do is compensate for the eye’s shape. This allows the reflections to line up correctly so the eye can focus on objects both near and far. Contacts are also prescribed in some situations, but may not be recommended until after the patient has used glasses for a time.
Depending on your prescription, your doctor and your personal needs, it may be recommended that you have corrective surgery done. This type of procedure will get rid of the nearsightedness or farsightedness so the patient will not have to wear contacts or glasses at all.
Whether your eyes are a bit blurred, or you feel like an eye exam could diagnose a problem giving you headaches, keep in mind that an optometrist is available to help you. With proper testing and tools, you could get back to having clear vision in just a short amount of time. Visit this site to schedule yourself an eye exam in Chula Vista.
