Convergence insufficiency is an eye condition affecting eye coordination when looking at nearby objects. This condition may cause double or blurry vision when looking at things up close, like a smartphone screen or book.
It often begins during childhood but can affect adults following a brain injury, such as a concussion. Early treatment for convergence insufficiency can help your eyes work together to see nearby objects.
Convergence insufficiency usually causes problems during close-up activities such as using a computer or reading. The most common symptoms include:
People with convergence insufficiency may also experience difficulty reading. You may read slowly, lose your place, feel like the words float, or move around the page. If a child experiences convergence insufficiency, you may notice the child has problems reading or doing several close-up activities. Your child may:
If you notice your child has any of these symptoms, ensure to talk to an eye doctor. Teachers and parents may mistake these difficulties a child experiences as an inability to learn or read, but the problem is a vision impairment that requires treatments.
Convergence insufficiency occurs when the nerves controlling your eye muscles do not work properly. Usually, when focusing on something up-close, your eyes turn in, but one eye turns out for people with convergence insufficiency.
Doctors aren’t certain why convergence insufficiency occurs in most cases, but research shows that it usually happens after a concussion or brain injury.
The eye doctor may first ask questions about your symptoms. They may also ask if you have double or blurry vision, trouble focusing, tired eyes, trouble focusing during close-up activities or headaches.
The doctor may also do some tests to check the following:
Your vision can be perfect, and you still have convergence insufficiency, so a regular eye exam is necessary.
Convergence insufficiency treatments involve a vision therapy known as convergence exercises. This usually includes working with a specialist to practice focusing on objects at varying distances. You can also carry out exercises at home and use a special type of glasses called prism glasses. In a few cases, surgery can help strengthen the eye muscles.
You may notice an improvement immediately after you start treatment, but in some cases, improvement in vision takes about 12 weeks or longer. Your symptoms may reoccur after you become sick, do not get enough sleep or engage in many close-up activities.

I had an absolutely wonderful experience doing Lasik at this clinic. Their entire staff was extremely professional and courteous throughout the entire process.
My surgeon was wonderful, made me feel entirely at ease before and during surgery. Highly recommended.
Laser eye surgery, now glasses free after 23 years! :)
I have always thought about laser, I have worn glasses for 23 years. I was very anxious, worried about the what ifs. I had an appointment with Dr Mani, he explained everything to me and I decided to go ahead with the surgery. It was so fast, Dr Mani did remind me to be patient and I think this is very important. I am now glasses free and hoping this will continue! After care was good, a week after surgery I was concerned and Dr Mani invited me down to check my eyes to be sure all was ok. Thank you
LASIK with Dr. Mani
I had LASIK surgery with Dr. Mani. It was painless, smooth, and everything went well. The staff and Dr. Mani are all friendly and will answer all questions asked. Will recommend 100%! Thank you!
I had a great experience performing my laser eye surgery at Optimal Vision Clinic. All the staffs are very helpful, co-operative and supportive throughout the treatment process. On the first call, they explained the entire procedure in details and gave necessary instructions at every stage. My eye surgeon made me feel comfortable and relaxed before and during the procedure. Aftercare was done properly with a thorough check-up of my eyes. I would like to recommend this clinic to everyone!
Very happy and impressed with the highly professional care and service I’ve received at the Optimal Vision clinic. Dr Mani is so professional, and he explained everything about Laser surgery and answered all my questions. The surgery was quick and almost completely painless. My eyes have healed perfectly and quickly. I would highly recommend this clinic.
My husband had been experiencing discomfort in his left eye since July and was seen by various doctors/consultants even at the Queen Mary’s hospital but no abnormalities were found.
This week Dr. Mani discovered the fault which happened to be Retina detachment with three tears.
Dr. Mani’s preciseness and his perfectionist attitude to attention to details, detected the source of the main issue and saved my husband’s eye. We feel utterly grateful and can not recommend him enough for his excellence.
