Do I need to remove my contact lenses for a visual examination during a physical examination

During the visual examination, it is necessary to remove the contact lenses.

Vision examination measures the eye's ability to focus on images through optical instruments, and wearing contact lenses may interfere with the accuracy of the examination results. The colored layer of contact lenses can change the path of incident light, affecting the refractometer's judgment of refractive error. Some contact lenses have prescription, which may mask real vision problems. The material of contact lenses may cause slight corneal edema, affecting the measurement of intraocular pressure. Long term use of contact lenses may cause dry eye symptoms and interfere with tear secretion assessment. It is recommended to remove the contact lenses at least 1 hour before the examination to restore the cornea to its natural state.

Contact lenses should be stopped for 1-2 days before physical examination to avoid changes in corneal morphology affecting corneal topography examination. You can carry contact lens care solution and glasses case with you for easy re wearing after inspection. If it is necessary to wear it due to special reasons, the doctor should be informed in advance of the parameters such as the base arc and diameter of the contact lenses. After examination, if there is redness in the eyes or foreign body sensation, seek medical attention promptly to investigate complications such as keratitis. Daily wear of contact lenses should be reduced, and 2-3 days of rest should be given to the eyes per week.
