Astigmatism is a refractive error in the eye. When the eyes is impaired, the patient's ability to focus light and images is diminished to varying degrees.
1. Causes of Astigmatism
Astigmatism is a condition in which the shape of the cornea is irregular. In cases of normal people, light rays pass the cornea then focus on one single point on the retina so they can see a clear image. However, in astigmatism people, light rays scatter to multiple points, which results blurred vision. Beside, astigmatism people have other symptoms: eye strain, headaches, and watery eyes.
There are some types of astigmatism:
- Astigmatism
- Myopia
- Astigmatism
- Astigmatism
- Mixed astigmatism
2. What level of astigmatism should you wear glasses for?
Using glasses intended to assist in the treatment of astigmatism. Usually more than 1 diopter astigmatism causes many visual disturbances. If your vision significantly impacted, you should wear glasses to reduce the strain on your eyes from excessive focusing
For people with mild myopia or slight nearsightedness, if there are no symptoms of eye strain or dryness and their vision remains clear, wearing glasses regularly is not necessary.
If there was any symptoms of eye strain or dryness, you need to wear glasses regardless of the extent of your myopia.
Using glasses depends on the severity and the patient's condition.
3. Adjusting to Glasses for Astigmatism
When you wear astigmatism glasses for the first time, your eyes might feel uncomfortable, even if the glasses are perfectly made.
However, if you wear glasses persistly for about a week, your eyes will adjust, and the feel of discomfort will go away.
4. What Type of Glasses Should People with Astigmatism Choose?
There are many type of glasses, like regular glasses, contact lenses, or even hard contact lenses (overnight orthokeratology lenses). Depending on your needs and preferences, you can chooes the best option. Before deciding, you should consult with an eye doctor to get the most accurate recommendations.
Furthermore, choose relieble places for crafting your glasses. Poor-quality or ill-fitted glasses not only fail to correct astigmatism but may exacerbate the condition and, in severe cases, contribute to amblyopia
