Sleep-aiding eyewear that prevents light which inhibits melatonin production from reaching the eye is described. The eyewear that is the object of the present disclosure has improved visibility over other methods of cutting off melatonin-inhibiting wavelengths of light, which enables the user to perform tasks, such as reading and typing, uninhibited. This is achieved in some embodiments using a Bragg grating comprising multiple layers of alternating reflective index material as a surface coating on the lens. This may be combined with lens-tinting, or antireflective coatings, in the eyewear. Furthermore, transition lenses which block melatonin-shifting light when there is a suitable external stimulus, such as blue light from a light emitting diode, are described. The presently described filters are also useful for electronic displays and functional light-transmitting materials.

Use of high resolution environmental scanning electron microscopy to capture images of contact lens coating layers, enabling measurement of the coating thickness and structures of the coating layer to be precisely characterized. The coating layer can be directly visualized and quantitatively measured. Furthermore, controlled environments of varying temperatures and varying levels of relative humidity can be established in environmental scanning electron microscopy, such that the dynamic changes of the coating in such conditions can be imaged and measured. The controlled environments can be set up to mimic either the manufacturing process conditions, or be set up to simulate lens-on-eye conditions.
