What is astigmatism and why does it complicate wearing contact lenses?
Astigmatism is a very common refractive error caused by a cornea or lens that is slightly irregular in shape — rather than being perfectly spherical, the cornea curves more along one axis than another, much like the surface of a rugby ball. This means light does not focus at a single point on the retina, producing blurred or distorted vision at both near and far distances.
For a long time, astigmatism was corrected only with glasses. Conventional spherical contact lenses could not compensate for the corneal irregularity because they rotated freely on the eye. Today, however, toric lenses exist — designed specifically for astigmatism — and they have changed the situation completely.
What are toric contact lenses?
Toric lenses have two different curvatures along their axes, which is exactly what an astigmatic eye needs to focus correctly. They also incorporate a stabilisation system — ballast weighting at the bottom, bevels, or stabilisation zones — that prevents them from rotating on the eye when you blink. This keeps the corrective power permanently aligned with the astigmatism axis.
- Soft toric lenses: The most widely used. Comfortable, easy to fit, and available in daily, biweekly, and monthly modalities.
- Rigid gas-permeable lenses (RGP): Offer superior optical correction, especially for high or irregular astigmatism (such as keratoconus).
Can I wear contact lenses if I have high astigmatism?
Yes, in most cases. Soft toric lenses correct astigmatism of up to -2.75 or -3.00 D effectively. For higher prescriptions, premium toric lenses or rigid lenses can be considered.
Important fact: 30% of the population has some degree of astigmatism. Many don’t know they can wear contact lenses comfortably.

How are contact lenses for astigmatism fitted?
- Complete refraction: We measure your prescription with full precision, including the astigmatism axis.
- Corneal topography: We map the exact shape of your cornea to select the most suitable lens.
- Fitting trial: We place the lenses and verify that stabilisation is correct — that they do not rotate and the axis is properly aligned.
- Follow-up: After 15–30 days we review how the fitting and comfort are progressing.
Tips for wearing contact lenses with astigmatism
- Always respect the recommended wearing schedule — never exceed it.
- Use the appropriate care solution for each lens type.
- If you notice fluctuating vision during the day, the lens may be rotating — consult your optician.
- Daily disposable lenses eliminate the risk of deposit build-up.
- Never sleep in soft toric lenses unless they are extended-wear and your optician has explicitly advised it.
When should you choose glasses over contact lenses?
Contact lenses are an excellent option for most people, but there are situations where glasses are preferable: environments with dust or smoke, periods of intense eye allergies, or when dry eye is severe.
Frequently asked questions
Are contact lenses for astigmatism more expensive?
Yes, slightly more than spherical lenses. Dailies range from €40–80 per box, and monthlies from €15–30 per box.
Can I buy toric lenses online?
You can reorder them online if you have already been fitted with us. However, the initial fitting must always be carried out with an optician.
Can I play sport with contact lenses for astigmatism?
Yes, and that is one of their main advantages. For water sports it is important to wear protective goggles.
How long does the adaptation period take?
Most people adapt within 1–2 weeks.
Do contact lenses fully correct astigmatism?
In most cases, yes. With very high or irregular astigmatism, rigid lenses can deliver even better results than glasses.
