In brief: It depends

If the difference is small, the brain can usually fuse the two images, especially with the help of glasses.
When it becomes very large (anisometropia), it becomes more difficult to fuse and can result in amblyopia. Contact lenses tend to be better tolerated in people with large differences than glasses.
