WebIf Point Selection is chosen, position the mouse cursor over an area that should appear either white or black in the image and click on the button to apply the appropriate algorithm to the specimen image. The Balanced Image window will automatically display the processed image with either the white or black correction applied. WebWhen buying a prescription mask, you need to order the correct corrective lens based on your current glasses or contact lens prescription. Masks usually come with premade lenses available in optical factor increments of 0.5. If your prescription is +3.75, you have to decide whether to order +3.5 or +4.0.
