Astigmatism
What is -25 astigmatism?
A -25 astigmatism refers to a very high degree of astigmatism measured in diopters, indicating significant irregularities in the curvature of the cornea or lens of the eye. This condition causes blurred or distorted vision at various distances. A negative sign indicates that the person is nearsighted (myopic) in addition to having astigmatism. Such a high prescription typically requires specialized corrective lenses or contact lenses for clear vision.

What is the astigmatism chart designed for?
The astigmatism chart was designed to evaluate whether a person has astigmatism, which is a condition which results in blurry or distorted vision. When a person looks at an astigmatism chart, all lines should appear to be the same darkness, clarity, and distance apart. A person with astigmatism will notice differences in the lines.
Can you get astigmatism later in life?
Astigmatism means that either the cornea or the lens of the eye is not shaped properly bending light as it enters and creating multiple focal points which are seen as blurriness. Astigmatism is something you're born with. Most people, many who don't wear glasses have some astigmatism, but not enough to notice or cause any problems. Astigmatism may get better or worse while our eyes are still developing usually between the ages of 8-22, but it won't develop suddenly. As we get older, our eyes start to degenerate and we need glasses for reading. A doctor prescribing glasses for reading will correct a very slight astigmatism as well; if you're wearing glasses anyway, you might as well have the best vision possible.

Which lenses should be used to correct the defect of astigmatism?
Astigmatism can be corrected with toric lenses. Toric lenses have different powers in different meridians to correct the varying degrees of astigmatism present in the eye. These lenses are designed to address the irregular curvature of the cornea typical in astigmatism.
Does astigmatism cause Anisocoria?
No. Anisocoria is a difference in pupil size and has nothing to do with astigmatism, which is a variation of the cornea or lens of the eye.
Can a scratch cause a astigmatism to get worse?
No, a scratch typically will not cause astigmatism to worsen. Astigmatism is usually caused by imperfections in the curvature of the eye's cornea or lens, and it is not typically affected by external factors like scratches. If you have concerns about changes in your astigmatism, it's best to consult with an eye care professional for an evaluation.
