- Reference marksOne mark at 3 o’clock and one at 9 o’clock. They show the lens’s horizontal position on the eye, so the practitioner can see whether it has rotated.
- Double slab-offThe lens is thinner at the top and bottom than across the middle. This helps it keep a stable orientation.
- Why orientation mattersA toric lens corrects astigmatism along one axis, so it has to stay in the same position on the eye.

FAQ
Questions about toric lenses
From the approved patient FAQ. Your eye care practitioner will advise on your own eyes.
All questionsCan contact lenses correct astigmatism?
Yes. Toric soft contact lenses, RGP lenses and certain custom designs can correct astigmatism. The most suitable option depends on your prescription, corneal shape and visual needs.
Are contact lenses comfortable?
Many people find contact lenses comfortable after a short adjustment period. Soft lenses usually feel comfortable quickly, while rigid gas permeable (RGP) lenses can take longer to get used to. Ongoing discomfort should be checked by your eye care professional.
Can I wear contact lenses every day?
Often, yes. Many lenses are intended for daily use, provided your eyes remain healthy and you follow the prescribed wearing and replacement schedule. Your practitioner will advise how many hours to wear them and when to take breaks.
Can I sleep while wearing contact lenses?
Do not sleep in ordinary daily-wear lenses. Some specialised lenses, including prescribed overnight Ortho-K lenses, are designed for sleeping, but overnight wear carries an increased risk of serious eye infection. Only sleep in lenses if specifically instructed by your eye care professional.
