Eye Doctor Can'T Get One Eye To See 20/20? Two Possible Reasons Why

If your eye doctor does an eye test and cannot get one of your eyes to see 20/20 this is a sign that something is wrong. This is because your eyes should be able to be corrected with lenses so you can see perfectly. You doctor will order tests for you to determine the cause of this problem. Below are some things the doctor may find that is wrong with you so you can be prepared for your next appointment.

Macular Degeneration

You could possibly have macular degeneration in one of your eyes. This does lead to partial blindness or complete blindness depending on the type of macular degeneration you have.

One type is called dry macular degeneration. If you have this, you will not go completely blind but your vision will be very blurry. With this, the retinal pigment epithelial cells in your macular start to thin or break down.

With wet macular degeneration, you will eventually go completely blind in that eye. You will have abnormal blood vessels growing under your retina. They grow towards the macula and continue growing until the macular is completely covered.

The macula is what surrounds the center of your retina and provides you with the best vision.

There is no cure for macular degeneration and no treatment options that will allow you to regain your full vision. Also, if you have it in one eye it can spread to your other eye also.

The doctor may ask you to take eye vitamins to help slow the progression.


Even though glaucoma typically is in both eyes it can start out in only one eye. It does usually spread to the other eye over time, however.  Glaucoma damages the optic nerve. This is caused by fluid building up in front of the eye. Over time the fluid increases causing the pressure in your eye to increase. This then damages the optic nerve.

Besides having blurred vision in your eye some other symptoms, you will likely experience include eye pain, headaches, nausea, and vomiting. You will also see halos or rainbow rings around lights. If not treated, you will start to see blind spots in your peripheral vision.

Fortunately, if the doctor finds that you have glaucoma they can do surgery to remove the fluid. You will then see normally again.

Talk with an eye doctor, such as at Quality Eye Care, about macular degeneration and glaucoma and they can give you much more information to help you.
