Many programs at LWTech are focused on concentrated eye use. Learning about eye health is important for all students who use their sight as part of their learning.
First, light passes through the cornea (the clear front layer of the eye). The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil (PYOO-pul). The iris (the colored part of the eye) controls how much light the pupil lets in. Next, light passes through the lens (a clear inner part of the eye). The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see. Your eyes also need tears to work correctly.
The Washington Academy of Eye Physicians and Surgeons maintains information for healthy eyes for every stage of life. The National Eye Institute also suggests that as you age, it is normal to notice changes in your vision. Vision changes can make it difficult to perform everyday activities, such as reading, walking safely, taking medications, performing self-care and household tasks, and driving.

Many LWTech programs require eye protection when working on projects in the classroom. Read your class syllabus for dress code policies, or ask you professor for more information if you have questions about eye protection requirements. Proper eye wear for some classes are available for purchase in the college bookstore.
