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:)
It's normal for it to take between one and two weeks to get used to the glasses. It's like this because when looking through the glass it's through an angle where your contacts are direct. Your eyes will adjust soon enough to the glasses.sually one day is enough for your eyes to acclimate to the new prescription. If you're worried about driving, you can probably make it after a few hours.
