First time wearers, especially wearers of progressive lenses, might possible experience an "adjustment period".
Even for experienced glasses wearers (with new lenses) a period of adaptation may be required especially when there is a change in prescription. Pay attention when going up and down the stairs.
Progressive Lenses
In progressive lenses, different areas of the lens are used for different viewing distances.
-
Far vision area
-
Intermediate area
-
Near vision area
-
Peripheral area
Don’t be discouraged, because very soon you will learn to adapt to the slight peripheral distortion ‘’swimming effect’’.
Instructions
While looking through different areas of the lens, you will observe that the center of each area will provide you a better vision.
Far vision area
Use the Far vision area which is located at the top part of the lens.
Intermediate vision area
Use the intermediate area at the center of the lens, when talking to people, or looking at a computer screen.
Near vision area
Bring your chin forward in order to look into the near vision area in the bottom of the lens.
Mid –Distance Lenses
In mid –distance lenses different areas of the lens are used for different distances.
-
Near vision area
-
Intermediate area
-
Peripheral area
Don’t be discouraged, because very soon you will learn to adapt to the slight peripheral distortion ‘’swimming effect’’.
You will soon learn and adapt to the slight swimming effect at the peripheral area.
Instructions
While looking through different parts of the lens, the center area at each part of the lens will provide a better vision.
Near vision area
It’s better to look through the near vision area when reading a book or newspaper
Intermediate vision area
Use the intermediate vision area on the top part of the lens, when talking to people or working at a computer screen.
Note: Viewing distances differ in Mid-distance lenses, depending on the age or wearer’s adaptation ability.
