Contact lenses are an established and safe method of correcting visual impairments. They provide a wider field of vision, in many cases better visual acuity, and do not fog up, providing comfort and freedom throughout the day. They simply enable good, clear vision without the need to wear glasses. When combined with glasses, contact lenses are the perfect complement to correcting a visual impairment. You can use both forms of correction interchangeably: in the morning at work or school you can wear contact lenses, in the evening at home when studying or using the computer you can wear glasses.
