How many glasses do you need?

There are new kinds of lenses for for eyeglass wearers coming onto the market all the time: lenses for use with digital devices, lenses for working with computers, lenses for driving and self-tinting lenses that react to light and UV. But just how many pairs of glasses do you actually need? Here are our tips to help you find what you need from among the enormous variety of glasses now available.

1.Perfect for every situation: everyday glasses

Whether we're talking about single vision or progressive lenses, you need a pair of glasses which optimally supports your vision! From selecting the lenses to choosing the lens features and selecting the frames – don't leave anything to chance. Your glasses should become one of your most prized possessions, making you happy while providing optimal vision. Just like a second skin, the frames should fit your personality, your facial features and many, if not all, of your outfits. They should not pinch your nose, be too heavy or cause allergic reactions. Everything needs to be perfect. With progressive lenses, the individual vision zones must be tailored to you and your vision.

2.A second pair of glasses for sunny weather: outdoor glasses

First-time eyeglass wearers often wear their normal sunglasses without prescription if they have low powers. If you suffer from eyestrain with your normal sunglasses but don't want to buy a new pair, self-tinting lenses lenses can be a good choice. They can turn a pair of everyday glasses into sunglasses which darken in sunlight – and of course there's 100% UV protection, too.

3.When glasses become a specialty and offer additional convenience for specific activities.

Digital Lens ---Helping users of smartphones and other digital devices battle eye fatigue
It's not just the younger generation that uses digital and mobile communication devices such as smartphones, tablets, etc. These common devices assist people of all ages. However, the working distances with these digital devices are even shorter than with print media. For people 30 years old or more, this means that it takes more effort for their eyes to continuously look at something up close. Tired, sometimes dry or fatigued eyes are often the result of using mobile devices for many hours per day. Special lenses (such as Digital Lens) can relieve your eyes and assist you when reading at short distances.
Computer glasses ---For reading and working more comfortably with vision problems in the close-up range
Starting at a certain age, our near vision begins to abate steadily. You find that you can only read a restaurant menu, book or newspaper by holding it far away. This not only looks unusual, but it's strenuous over the long term. This is where a pair of reading glasses can be a particular help as your primary or secondary pair. If you already wear progressive lenses every day, it can prove worthwhile to indulge in a pair of reading glasses so that you can read comfortably on the coach.
Do you spend a lot of time sitting in front of the computer? Then progressive lenses or reading glasses are not always optimal because your posture varies. Non-ergonomic or even a tense posture while sitting at your desk often prevents optimal vision and can even damage your health. In this case, investing in computer glasses can be a great solution to satisfy your special vision needs when sitting at your desk.
Sports glasses---The best vision for your favorite hobby and when playing sports
These are life's special moments: when you're doing the thing you love or playing your favorite sport. However, your everyday glasses or sunglasses are not always perfect for your sports and hobbies. Sports glasses offer special protection against dust, dirt, sun or small pebbles in the air in the form of wrapped frames. If you need vision support, ZEISS Sport lenses can become your high-performance sports gear. A special technology makes optimal, undistorted vision possible even in the wrapped peripheral zones of the lens.
Do you require special tints, glare protection or contrast enhancement for your favorite sport? Single and gradient tints in the colors of your choice, or sunglasses with a polarization filter give you better vision and may improve safety and performance when you're playing sports.

4.Just in case: a spare pair of glasses.

Although generally not very popular, they're helpful in an emergency: the spare pair of glasses. Eyeglass wearers who depend on their glasses need them as much as contact wearers. You keep them in your car's glove compartment because you're required to wear them when driving. Long-term eyeglass wearers have it easier because their old pair of glasses often serves as their spare pair.
