Visual aids are tools used to help people with vision problems. SPECS is an acronym for spectacles, which are frames with LENSES that are used to correct vision. LENSES are the curved pieces of glass or plastic that are placed in the frames to help focus light onto the retina. EYES are the organs of sight that receive light and convert it into electrical signals sent to the brain. EYEPIECES are the parts of a microscope or telescope that are placed close to the eye to magnify the image. GLASSES are frames with LENSES that are used to correct vision. EYEEXAMS are tests performed by an optometrist to check the health of the eyes and to determine the need for corrective LENSES.
