Abstract: The current invention is a new glass windshield with a transition-lens type composition layer between the glass substrates for use in vehicles (airplanes, ships, boats, sailboats, steamers, yachts, jets, and cars) or residential and commercial buildings to protect against sun glare and provide an overall cooling effect on the passengers or inhabitants. Rather than permanently tinting the glass of windshields and windows, the current invention works only when needed. It activates in the presence of sunlight. By not darkening unnecessarily, it avoids the consistent darkening of the interior of a vehicle (airplanes, ships, boats, sailboats, steamers, yachts, jets, and cars), viewing panel of an accessory such as a motorcycle or skydiving helmet, or residential and commercial buildings, as is the problem with tinted glass. The new glass windshield can be used as is or as a detachable or attachable unit.
