Abstract:
Zero parallax visual axis glasses for corneal pre-marking include a target light, an alignment light, a polarized lens and a short pass filter. In some embodiments the targeting light and/or alignment light are LEDs and/or configured to blink. In some embodiments the target light is red. In certain embodiments the alignment light is white. The polarized lens can be placed on a user's non-dominant eye and block light originating from the target light and/or alignment light. The short pass filter can be configured to allow light from the target light to only pass through in one direction.
