Focus on your vision
Your eyes allow you to see shapes, colors and movement as well as perceive distance, height and other variables around you.
How you see
The images you see are made up from the light reflected off the objects you look at, which then enters your eye through the pupil. Together with the lens, the cornea bends (refracts) the light to focus on the retina at the back of your eye. The retina is covered with millions of light-sensitive cells called rods and cones. Cones are responsible for daytime vision – and allow you to see images in color and detail – whereas rods are responsible for night vision. The retina converts light into electrical signals. These pass along the optic nerve to your brain, which then processes them to create an image.
How you focus
The lens of your eye focuses the image. It does this automatically, using muscles to change shape and help focus on objects at different distances. The iris, the colored part of your eye, controls the amount of light passing through the pupil into your eye.
Take care of your vision
Visit your optician regularly to have your eyes examined. In between examinations, if you notice a change in or are concerned about your eyesight, contact your nearest Hoya Vision optician. Hoya Vision lenses offer vision correction and its coatings/treatments can also protect your eyes. Detecting and treating problems early can help maintain good vision for the rest of your life.
