Something that causes a response in a body part or organism. A stimulus may be internal or external. Sense organs, such as the ear, and sensory receptors, such as those in the skin, are sensitive to external stimuli such as sound and touch.
Just curious...given my insurance plan I can get a new pair of frames and lenses once every 2 years, but I realllly love glasses so I tend to purchase about 2 pair per year...Gotta have my style...oh and of course the added benefit of sight is a nice plus:)
How long do prescription glasses take to make? Ordinarily your prescription glasses should take 5 â 7 business days to be ready for dispatch or collection, however, this can be dependent on your prescription, frame and lens choice.
