Less-than-perfect eyesight won’t just make your world look a little blurred. Left uncorrected, poor eyesight can lead to frequent headaches and eyestrain, and may even make driving and other activities more dangerous.
That’s why it’s important to regularly have comprehensive eye exams—and the right eyeglass prescription. ZEISS has many types of lenses, coatings, and diagnostic equipment to keep your world in focus. Here’s a quick look at the most common vision problems, and how an eye care professional and ZEISS can help you start seeing better.
If you have myopia, you can see close objects clearly, but distant objects are blurry, because your eyes focus images at a point in front of your retina instead of on it.
To bring those distant objects back into focus, you’ll be prescribed an eyeglass lens that will move the focal point back to the correct spot on your retina. Eyeglass lenses, such as Individual® lenses by ZEISS, correct for myopia.
If you’re farsighted, your eyes focus images at a point behind the retina, which can make objects that are close seem blurry.
To improve your sight, you’ll need an eyeglass lens to move your eyes’ focal points onto the retina. Eyeglass lenses, such as Individual® lenses by ZEISS, correct for hyperopia.
An eye with astigmatism has an unevenly curved lens, which creates multiple focal points that fall either in front of or behind the retina, causing everything in the image to appear blurry. Most often, astigmatism occurs with either hyperopia or myopia.
To correct astigmatism, lenses are prescribed to make the focal points properly hit the retina. Eyeglass lenses, such as Individual® lenses by ZEISS, correct for astigmatism.
As you get older, the lenses of your eyes thicken and lose flexibility, making it harder for them to adjust and focus on nearby objects. This is a natural part of the eye’s aging process. It often becomes a problem after turning 40, and you may start holding menus or newspapers at arm’s length to read them and experience eye fatigue along with headaches when doing close-up work.
Even if you’ve never used glasses, you may need them now. To help you compensate for presbyopia and age-related vision changes, your optometrist can prescribe reading, single vision, bifocal, trifocal, or progressive lenses. Modern progressive lenses, such as the ZEISS Progressive Individual® 2 (Patent), offer key advantages over bifocal and trifocal lenses. These lenses make sharp vision possible, without interruption of vision from one viewing distance to another, and without a visible line on the lens.
Progressive lenses have a subtle shift between the power in the upper part (for distant objects) and the lower part of the lens (for reading and other close work). And unlike bifocals, there’s no visible, distinct line between the distance and reading parts of the lens. Instead, they are linked by an area of gradually changing power, which also provides vision for intermediate distances at arm’s length. And they’re designed to be worn all day — so your entire world stays in focus.

On the road
When you’re driving, sun glare or darkness can make it hard to see dangers in the road ahead. Polarized anti-reflective lenses by ZEISS can make it easier for you to see in less-than-ideal conditions. Polarized lenses help you see clearly in dazzling sunlight, improving your ability to see color and contrast in extreme glare while significantly reducing distracting reflections off the road, water, or other surfaces. And i.Scription® (Patent) technology provides you with the clear, high-contrast vision you need while driving at night and in low light, such as twilight.
At the office
If you spend long days in front of a computer or at a desk, your glasses should help you focus on your work. ZEISS Office/Computer lenses keep your close and mid-range sight crystal clear, with less eye strain and visual fatigue.
When you are busy outdoors, the sun and sun glare can affect your vision. Sun lenses improve your ability to see in extreme glare, and will help protect your eyes from the harmful effects of UV rays. Polarized lenses will improve vision outdoors even further by selectively blocking glare reflected from shiny surfaces, like water, snow, or asphalt. And self-tinting lenses deliver excellent vision under most lighting conditions—at night or indoors they remain clear, on cloudy days they turn semi-dark, and in full sunshine the lenses darken to a true sunglass tint.
