“How would the optometrist prepare my eyes to test for cataract?”

We have a few ways to check for cataracts, first we check your vision, (normal is 20/20 ) if you have decreased vision that is not correctable with glasses this could indicate a cataract. Next the doctor will dilate your eyes to allow them to evaluate the lens in your eye. The Lens is like a clear window and as you get older it becomes more yellow and cloudy... causing your vision to decrease, (similar to looking out a dirty window) . If the doctor see's a cataract in the eye then they can suggest to either continue watching it and getting updated glasses (as cataracts are very slow growing and can take time to affect your vision) , or recommend surgery depending on the severity of the cataracts.

One of the first signs you will notice that indicate your cataract is getting worse is difficulty driving at night and bright lights are bothersome (especially car headlights). And if you play golf you can have a hard time seeing the ball.
If you have not had an eye exam in 10 years I highly recommend to do so.

During a thorough eye exam, the eye doctor will look at your eyes through a slit lamp biomicroscope to see if you have a cataract. There are also tests to rate the level the cataract is impairing your vision. 

The doctor will check your vision to get a baseline visual acuity to assess how much you can see. If you do not see all of the letters, the doctor will see if glasses will improve your vision. If glasses do not improve your vision, then the doctor will take a look at the inside of your eye to assess the cloudiness of the cataract to see if it is ready for removal.

The doctor will check your vision and eye health and, if appropriate, will make a referral to the cataract specialist surgeon.

You will have a refraction, examination by microscope, glaucoma check, and dilated retinal examination. Be prepared to have blurred vision for a few hours after the examination as you recover from the drops.

Cataracts are easily visible with a slit lamp and any optometrist will be able to identify the cataracts and let you know whether or not it is ready for surgery or if it is just shifting your prescription. A full, dilated eye exam should be performed, especially since you have not been seen in 10 years. There are lots of things besides cataracts that can blur your vision and a thorough eye exam is long overdue!

Very simply. The doctor will dilate your eyes with drops and check the type and grade of cataract.

You should see an eye doctor every 2 years. Cataracts can easily be seen by your doctor!
