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.
Astigmatism Types
Hyperopic Astigmatism:
In this instance, one or both principal meridians are farsighted. They are considered hyperopic in different degree if both are farsighted.
Myopic Astigmatism:
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.
Mixed Astigmatism:
When one principal meridian is farsighted and the other is nearsighted, a mixed astigmatism occurs.
Regular vs. Irregular Astigmatism
Once we detect what is happening with your astigmatism and if one or both eyes are affected, we will be able to help you determine the best route to take. Rest assured knowing that your blurry days will be behind you soon!
Irregular Astigmatism:
Defined when the principal meridians are not perpendicular.
Regular Astigmatism:
Defined when the principal meridians are perpendicular to each other or 90 degrees apart.
The majority of astigmatism cases are comprised of regular corneal astigmatism where the front eye surface has a football shape instead of a round baseball shape.
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.
Will My Astigmatism Go Away?
Some clients choose to undergo Lasik eye surgery once their prescription stabilizes after their teenage years. Others clients notice it becomes worse with age and new prescription glasses are required. Every patient is different. Some have hereditary factors to consider while others develop astigmatism by subjecting their eyes to a lack of oxygen from over wearing their contact lenses. At the first indication of not seeing things crystal clearly, it is wise to book an eye exam in order to get to the heart of the matter.
