My daughter has severe farsightedness in one eye and was diagnosed with refractive amblyopia. She just received her glasses, and one lens is much thicker than the other. She is complaining that the glasses make her dizzy and she won’t wear them. Can anything be done about this?


When one eye needs much stronger vision correction than the other eye, contact lenses are sometimes preferable to eyeglasses. Unequal lens powers in glasses can cause an unequal magnification effect, so the eyes transmit images to the brain that are not the same size. The brain may not be able to blend these two images into a single one, which often causes dizziness and nausea. In addition, your child’s eyeglasses may be unattractive and causing her to not give them a real chance to adapt.

Contact lenses obviously grant a nicer appearance, and they don’t cause as many problematic variations in image magnification. Even young children can handle wearing contact lenses, and one-day disposables or continuous wear lenses (worn consistently for up to 30 days) are possible options.

With amblyopia, one eye doesn’t see as clearly as the other eye, even with the best contact lenses in position. Vision in her weak eye may not be drastically improved with contacts, and vision therapy will probably be needed too. Best to discuss all her options with her Eye Doctor.
