Final answer:
California state law mandates that protective lenses shall be used during fluoroscopy. The law intends to protect individuals involved in the procedure from harmful radiation, akin to the way specialized glasses protect eyes from UV light during an eclipse or welding. option 2 is correct.
Step-by-step explanation:
According to California state law, protective lenses shall be utilized during fluoroscopy. This is an imperative directive, suggesting that it is a legal requirement, not just a recommendation. Protective eyewear is essential in shielding the eyes from harmful radiation during fluoroscopy procedures.
This is much like how specially designed eclipse glasses and welders' goggles provide crucial protection from the Sun's UV radiation, which can otherwise cause severe damage to the eyes. In a medical setting, such as during fluoroscopic procedures, the use of appropriate protective lenses ensures the safety of healthcare professionals and patients from potential exposure to ionizing radiation.
In the context of eye health and light interaction, a cataract is a condition where cloudiness occurs in the lens of the eye, leading to the dispersion of light. When repairing a retinal tear with laser surgery, the light rays entering the eye must be parallel to accurately spot-weld the retina to the back of the eye. This is important for maintaining the correct focus and preventing further damage to the eye structures.
Individuals with lens-to-retina distances smaller than 2 cm often require glasses due to the eye's inability to adequately focus light on the retina, leading to blurry vision. For such conditions, converging lenses in glasses are typically prescribed to correct the focus, allowing the person to see clearly. Ray diagrams can illustrate the difference glasses make for someone with a lens-to-retina distance shorter than normal.
