Your eyeball has a round shape, similar to that of a baseball. When this shape deviates and takes an elongated form, astigmatism develops. For your understanding, our trusted Bothell optometrist from Alderwood Optical and Canyon Park Vision Clinic answers some common questions about this refractive error.
Who is At Risk?
Although it can affect anyone at any age, studies show that it can develop as early as 5 years old. That’s why we emphasize the importance of eye exams in children. A family history of this condition increases your likelihood of developing it as well. The earlier you start caring for your eyes, the better chances you have of keeping your vision intact.
What Causes this Refractive Error?
There is no single cause for the development of this condition. Most cases, however, pinpoint inborn structural irregularities as the underlying cause of this refractive error. For instance, corneal astigmatism happens when the dome-shaped structure of your eye, also known as the cornea, becomes irregularly shaped.
In the lenticular form, the lenses of your eyes show uneven surfaces. In both cases, they cause the light to bend at different angles and focus on multiple areas instead of a single focal point.
What are the Signs and Symptoms?
The hallmark sign is blurry vision. You may also experience frequent headaches, squinting, and eyestrain. If you experience any of these, call us immediately. We can provide superior optical care in Bothell, WA, to manage this condition and prevent its progression.
What are the Recommended Treatments?
For mild to moderate astigmatism, we may prescribe corrective eyeglasses as an initial remedy. We may also recommend wearing toric contact lenses. Their donut-like shape helps in better focusing of light as they enter your eyes.
Our reliable eye doctor in Bothell, WA, may also offer orthokeratology. This non-surgical procedure uses gas-permeable lenses to reshape your cornea while you sleep. Once you wake up, you may remove them and enjoy a day’s worth of clear vision. For more severe cases, we may also recommend refractive surgery.
