Description
These Near Point Dot cards are double-sided cards for measuring the near point of convergence (dots) and of accommodation (letters), and for home exercises. Home exercises with dot cards treat convergence insufficiency more effectively than simple pen push-up exercises by ensuring correct ocular alignment and no suppression.
The card has a central crease to maintain its stability and ease of use. The dots are placed at 3 cm intervals along the card, which is held lengthwise touching the end of the nose so that the dots are 6 cm to 33 cm from the eye (approximately). On the reverse are two columns of letters spaced at 2 cm intervals.
