The Amsler grid may be helpful in revealing signs of wet age-related macular degeneration (ARMD). However, use of the grid is not a substitute for regular eye tests.

Instructions :

• Do not remove the glasses or contact lenses you normally wear for reading.
  
• Stand approximately 33cm from the grid in a well-lighted room.
  
• Cover one eye with your hand and focus on the centre dot with your uncovered eye. Repeat with your other eye.
  
• If you see wavy, broken or distorted lines, or blurred or missing areas of vision, you may be displaying symptoms of ARMD.
