The eye must be able to change its refractive properties to focus images of both distant and nearby objects on the retina. Distant objects (greater than 30 feet or 9 meters away from the eye) emit or reflect light that can be focused on the retina in a normal relaxed eye (Figure 14.8).
Ramona is a census-designated place (CDP) in San Diego County, California. The population was 20,292 at the 2010 census. The term Ramona also refers to an unincorporated community (with some plans to incorporate) that includes both the Ramona CDP and the adjacent CDP of San Diego Country Estates.
A student is considered chronically absent if he or she misses 10 percent or more of the 180-day school year. At Ramona Unified, 473 chronically absent students cost the district $355,566.77 last year. Twenty-seven of them missed at least a quarter of the school year. Two were absent more than 100 days. On average, a student with perfect attendance is worth about $5,230 to a school district in San Diego County. Every day missed reduces that amount by about $29. It may not sound like much, but the multiplier effect can be financially staggering for some schools.
