Early Detection

An eye examination comes before choosing overnight lenses.

Possible Signs of Myopia

Blurred distance vision, such as difficulty seeing the classroom board.
Squinting or changing position to see distant objects.
Headaches or eye strain, which can have causes other than myopia.
Unusually close viewing of books or screens.

Before Considering Overnight Lenses

Arrange an eye examination when symptoms arise and follow the review interval recommended for you or your child.
Discuss prescription, corneal mapping, eye health and lens handling before deciding on Ortho-K.

Harness Our Treatment Methods

An Ortho-K assessment checks your prescription, eye health and corneal shape, then considers treatment options and the practical demands of lens care.

Your Ortho-K questions answered

Does blurred distance vision mean I need Ortho-K?

Not necessarily. An examination first establishes the cause of blur. Glasses, daytime contact lenses or other care may be more suitable than Ortho-K.

What does corneal mapping show?

Corneal topography measures the shape of the front surface of the eye. It helps the practitioner assess suitability, design lenses and monitor the response to Ortho-K.
