Goggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Though goggles essentially were indicative of protective eyewear, used in industries or while indulging in adventure sports, it has gradually taken its firm place in normal day-to-day life, as we now know of the importance of using them.Many types of goggles are available as prescription eyewear for those with vision problems. While a pair of goggles helps reduce strain on our eyes, it has also been found to reduce the incidence of premature wrinkling of facial skin – ‘crow’s feet’ in the outer corners of the eyes and lines on the forehead, because it curbs our tendency to squint in harsh sunlight. However, one needs to ensure that the level of ultra violet protection it offers is sound lest it cause irreversible damage to the retina that may result in impaired vision. This is because, the dark tint on the glasses causes the pupil of the eye to dilate more than it would under regular circumstances, letting in more ultra violet rays which can harm the eye.
