Light and air easement is a type of negative easement. This easement prevents an adjoining land owner from building any structure that would obstruct the passage of light or air from reaching the dominant land.

Since you have perfected his right to light and air by prescription extended over 20 years of period, the easement right is established and this is an easement by prescription.

The extent of any other easement and the mode of its enjoyment must be fixed with reference to the probable intention of the parties, and the purpose for which the right was imposed or acquired. In the absence of evidence as to such intention and purpose-

Prescriptive right to light or air. -The extent of a prescriptive right to the passage of light or air to a certain window, door or other opening is that quantity of light or air which has been accustomed to enter that opening during the whole of the prescriptive period irrespectively of the purposes for which it has been used.
