Contact Lenses: Fittings, Comfort, and Complex Prescriptions

Contact lenses: what matters most

Most contact lens problems come down to:

• fit
• stability
• comfort over a full day
• and whether the eye surface is healthy enough for comfortable wear

Can I wear contacts with astigmatism?

Often yes — toric lenses can work well, but they need to fit and remain stable.

Dryness, blur, and screen-heavy days

If your lenses feel worse after long screen days, it may be more about tear film and blinking than your prescription.

When specialty lenses help

Specialty options may be considered when:

• standard lenses are uncomfortable or unstable
• you have a more complex prescription
• you have corneal or eye surface factors that require a different approach
• you have keratoconus or an irregular cornea — scleral lenses vault over the cornea entirely, providing vision and comfort that standard lenses cannot achieve. See scleral lenses for keratoconus and irregular corneas.
• you have severe dry eye that drops and other treatments have not resolved — scleral lenses hold a fluid reservoir against the eye. See scleral lenses for severe dry eye.
