Which of the following is NOT a function of safety goggles designed for laser use?

Safety goggles designed for laser use serve several important functions aimed at protecting the eyes from potential harm caused by laser radiation. One of their primary functions is to protect against laser radiation, which involves shielding the eyes from both direct and scattered beams. Laser goggles are specifically engineered to absorb or block certain wavelengths of light that lasers emit, thereby preventing retinal injuries.

Another critical function of these goggles is to filter specific wavelengths of light, which is essential because lasers come in various wavelengths, and the goggles are designed to selectively filter out the harmful ones while allowing safe wavelengths to pass through if needed. This ensures that the user can still see their environment without being exposed to dangerous levels of optical radiation.

Additionally, safety goggles can also help to reduce glare from the laser beam. This is important in maintaining visibility and comfort in environments where lasers are used, as glare can hinder a user's ability to see clearly and perform tasks safely.

However, safety goggles designed for laser use are not specifically aimed at enhancing clarity of vision. Their primary purpose is protective rather than optical enhancement; though they may not significantly distort vision, they do not enhance clarity beyond allowing safe vision through filtered wavelengths. Therefore, while they serve protective functions, enhancing clarity is not one of their primary roles.
