Lens drops are a preservative-free eye drop that temporarily relieves dryness caused by minor eye irritations. These drops work by pulling water into the surface layers of the eye. They come in a convenient single-dose vial and can be applied with a small squeeze bottle or dropper.
A magnifier is a device that enlarges an image and makes it easier to see. Magnifiers can be handheld or fixed, and the magnification is usually measured in diopters (the unit of measure for lens strength).
A fixed-magnifier typically has a concave object lens which forms an enlarged image at the focal point, and a hand-held magnifying glass typically has a convex lens.
Vision is a process that converts light into electrochemical signals and then transmits these signals to the brain. Due to the vital role it plays in our lives, we need to maintain excellent health of our eyesight. Vitamin A is important for healthy vision because it helps keep the eyes moist and heals dry eyes. This vitamin also works together with other nutrients such as lutein, zeaxanthin, and beta-carotene to promote good eye health.
Eye drops are used to help restore moisture in the eye, due to dryness or exposure to wind, smoke, or dust. They contain artificial tears that aid the eyes in maintaining the production of natural tears. Eye drops are usually applied three times a day, but this eye drop is only used once a day.
