Astigmatism is a common eye issue that is often detected early in childhood; however, it can occur at any age. Essentially, it refers to an irregularly shaped cornea that resembles more of a football instead of a symmetrically round baseball shape. This means that one meridian is curved more than the other meridian running perpendicular to it. There are different kinds of astigmatism including a lenticular astigmatism that is defined by the shape of the lens within the eye. Maintaining regular eye exams at iSight Optometry in Kelowna is the best way to be aware of your astigmatism and successfully treat it with a proper prescription.
In this instance, one or both principal meridians are farsighted. They are considered hyperopic in different degree if both are farsighted.
In this scenario, one or both principal meridians are nearsighted. They are considered myopic in differing degree if both meridians of the eye are nearsighted.
When one principal meridian is farsighted and the other is nearsighted, a mixed astigmatism occurs.

Vision Issues with Astigmatism
Blurred vision and squinting are hallmarks of astigmatism. This is due to the light not focusing in a single point within the eye. Clients commonly squint to try and compensate for the blurry images and fuzzy edges that they see. Many are unaware of having a slight astigmatism until it is detected in a regular eye exam. The good news is that astigmatism can be corrected once accurately diagnosed. Ensure that your family undergoes consistent eye exams with the professional optometrists at iSight Optometry in Kelowna to monitor any vision changes.
