"I spend time in dry or dusty environments."
Where you wear your lenses can be just as important as how long you wear them.
If you work in a dusty place, debris may get caught between your lens and your eye and cause discomfort, even if you can't see it. Frequent application of lubricating or rewetting eye drops that are approved for use with contact lenses can help keep your eyes and lenses comfortable.
Another remedy is orthokeratology, which is the prescription, fitting and use of special contact lenses to reshape your cornea while you sleep, allowing lens-free daytime vision.
