When you visit the eye doctor to obtain a new set of glasses, you must make a number of decisions. The lens index is one of the most crucial decisions. That might sound like a big, complicated word, but it's actually quite simple. The lens index is a special number that indicates how thick or thin your lenses will be. As a general rule, the higher the number, the thinner your lenses. This matters: lots of people like light, easy-to-wear glasses.
Your prescription is a bunch of numbers that your eye doctor writes after performing an eye test. These numbers inform the optician how to cut your lenses perfectly for you. Your prescription is a strong consideration when you are trying to decide which lens index to select. If you have a high prescription, which means you require a great deal of help to see clearly, you will require the higher lens index. This is because the highest lens index helps keep your glasses thin and light. If your prescription is not too strong, however, you can go with a lower lens index and still be sporting nice thin lenses. This is an excellent way to ensure that your glasses feel comfortable and flattering on your face.
Lens index is a major factor in determining the thickness and weight of your glasses. If your prescription is strong but you select a low lens index, your glasses will be thick, heavy, and uncomfortable to wear. But if you select a higher lens index, your glasses will become thinner and more lightweight. Higher index lenses bend light better than lower index lenses, and so this is why. That’s because when they’re able to bend light better, it’s less material that’s needed to assist in correcting your vision.” It is for this reason, that a lot of people prefers higher index lenses, because it gives them a more pleasurable experience while wearing glasses.
There are multiple lens index options, and there are pros and cons to each. Order lens indexing 1.50, 1.60, 1.67 or 1.74 is the one that people have in mind. This heavy offering, the thickest and heaviest, has the lowest index of 1.50. It is often the least expensive option, as well. The slimmest and lightest comes with a 1.74 index, the highest one. But it is also the most expensive option.
Opting for a higher index lens will provide better comfort is due to it being thinner and lighter, allowing you wear your glasses much more comfortably. A lot of folks also consider these lenses to look nicer since they do not distort the shape of your face as much as thicker lenses do. This may sound good, but keep in mind that higher index lenses are also seemingly more expensive. The difference in price can be off-putting to some, so it’s wise to consider what best fits you and your budget.
Lenses with correct index for your prescription for the perfect lens index. Picking a low lens index keeps those glasses thick and cumbersome, and that's not the most comfortable. Your vision can also be too poor to see when it’s time to get the glasses, which sort of defeats the whole point of glasses in the first place. On the other hand, it could be that you are choosing a lens index that is higher than what you require and paying for something you really do not need. This is what makes working very closely with both your eye doctor and your optician so important. They can assist you in locating the best lens index that works well for your eyes and allows you to see properly.
