Myopia:
Myopia, or "near-sightedness" is a condition where images are focused within the vitreous (clear gel-like fluid located inside the eye ) and not on the retina of the eye like normal. People may see clearly up close, however experience blurry distance vision.
This is correctable by prescribing corrective lenses such as glasses or contacts.
Strabismus:
Strabismus is a condition where both eyes are not able to be aligned simultaneously due to extra ocular muscle imbalance. There are different forms of strabismus (see chart) based on the particular incorrect alignment of the eye.
Misaligned eyes are not only a cosmetic issue. If left untreated, it can lead to the suppression of vision in one eye. It is therefore important to have your child evaluated as early as possible if you suspect any of these conditions.
There are many different forms of treatment including blurring eye drops, vision therapy, eye patching, and even eye muscle surgery. It is best to be evaluated by an ophthalmologist to determine the best course of treatment.
Hyperopia:
Hyperopia, or "far-sightedness" is a condition where images are focused at a point behind the eye. This is due to the eyeball being too short and the cornea being too flat, resulting in blurry vision.
This is correctable with corrective convex lenses such as glasses or contacts.
Astigmatism:
Normally, the cornea is a spherical or round part of the eye. In many cases, the cornea is actually elliptical and shaped more like a football. As a result not all of the light rays that pass through the cornea focus on the retina, which can make objects appear blurry.
Special curves put on glasses can correct this problem.
