The lens is crystal clear and allows light to pass through and focus on the retina in normal situations. Cataracts are cloudy areas in part or the entire lens of the eye. There is a decreased visual acuity because the cataract prevents light from easily passing though the lens. Print appears hazy and contrast is limited. Individuals have difficulty seeing in poorly lit environments due to decreased contrast. Distance vision can be blurred especially outdoors. Colors appear faded or changed in hue. Many people experience an increased sensitivity to light and glare. Visual functioning may be enhanced with the use of low vision devices such as microscopic and telescopic glasses, lenses that filter light, and magnifying glasses.
In classroom settings, students may be assisted by:
1. Use of bright primary colors with high contrast.
2. Reading materials that have high contrast, such as large black print on white or light Yellow paper.
3. Use of black felt-tip pens and bold, enlarged print a minimum of 18 point.
4. Reduction of glare by avoiding direct sunlight. (22)
