Good vision, for most, is essential to performing everyday activities; it contributes to overall well-being and makes you independent. But, if you have vision problems, you probably know of the many options that can help improve your sight. Because of convenience and comfort, many people have switched from glasses to contact lenses. However, not everyone may benefit from wearing off-the-shelf contact lenses. Specialty contact lenses San Antonio are a viable option for certain disorders such as astigmatism.

Below are hard-to-fit vision conditions that may benefit from specialty contact lenses.


Keratoconus is a progressive eye disease that occurs when your cornea thins and bulges outward into a cone shape causing blurred vision and sensitivity to light and glare. It usually affects both eyes, although the symptoms are often severe in one eye more than the other. If you have mild keratoconus, glasses or soft contact lenses might be enough to correct the vision problems. However, more advanced cases of keratoconus require custom-fit contacts such as rigid, gas-permeable, or scleral lenses. In other cases, a cornea transplant may be necessary.


Astigmatism results from mismatched curves on the cornea or the lens inside the eyes. Instead of the normal curve like a round ball, the surface is egg-shaped, causing blurred vision at all distances. Most cases of astigmatism are not pronounced enough to require corrective action.

Unlike spherical lenses, which rotate when you blink, toric lenses have different powers in different meridians, meaning they stay in one position. This is because toric lenses are weighted at the bottom and only move vertically.
