Increase font size WP

Is there a plugin for WordPress (widget) that my visitors could use to make the font size bigger?
As my newest website (under construction) also gets loads of half blind people on it.

I have tried lots of plugins from allready they they don't work at all!

class Zoom extends WP_Widget {
	function __construct() {
		$widget_ops = array('classname' => 'widget_zoom', 'description' => __( "Zoom in or zoom out font size of wordpress") );
		parent::__construct('zoom', __('Zoom Font'), $widget_ops);

	function widget( $args, $instance ) {
		$title = apply_filters('widget_title', empty($instance['title']) ? __('Zoom Font') : $instance['title'], $instance, $this->id_base);

		echo $before_widget;
		if ( $title )
			echo $before_title . $title . $after_title;

		<form method='get' action=''><input type='number' name='zoom' size='4' value=''/> % <input type='submit' value='Zoom'/></form>

		$instance = $old_instance;
		$instance['title'] = strip_tags($new_instance['title']);

		return $instance;

	function form( $instance ) {
		$instance = wp_parse_args( (array) $instance, array( 'title' => '' ) );
		$title = strip_tags($instance['title']);
			<p><label for="<?php echo $this->get_field_id('title'); ?>"><?php _e('Title:'); ?></label> <input class="widefat" id="<?php echo $this->get_field_id('title'); ?>" name="<?php echo $this->get_field_name('title'); ?>" type="text" value="<?php echo esc_attr($title); ?>" /></p>

function zoomfont() {

add_action('widgets_init', 'zoomfont');
########## END ZOOM WIDGET ##########

if(isset($_GET['zoom'])) {
	if(is_numeric($_GET['zoom'])) {
		setcookie('zoom', $_GET['zoom']);
	echo "<meta http-equiv='refresh' content='0; url=".$_SERVER['HTTP_REFERER']."'>\r\n";

function zoomtext() {
	$zoom = $_COOKIE['zoom'];
	echo '<style type="text/css">'."\r\nbody {\r\n\tfont-size: ".$zoom."%;\r\n}\r\n</style>\r\n";
if(isset($_COOKIE['zoom'])) {
	add_filter('wp_head', 'zoomtext');
save this script to your plugins folder, activate from wp admin and drag the Zoom Font widget to your sidebar.
you can zoom in or zoom out font size of your wordpress by %.

sorry if my plugins not work, i am newbie in PHP and new in wordpress :)

font-size: *%;
with * is value from cookies zoom.
