Is it necessary to get an eye exam even if I am satisfied with my ready made reading glasses? Definitely. The use of readymade reading glasses is perfectly safe but does not replace the need for regular eye exams. There are many silent robbers of vision that if caught early can be easily treated or prevented. Glaucoma is a perfect example of an eye disease that is often asymptomatic and will remain undetected without regular eye exams.If there is no value under the cylinder heading, then you have a simple prescription. If there is a value under this heading, then you have astigmatism. What are my options for the reading glasses at NeoVision? You can order your own custom reading glasses by choosing any of our eye glass frames and adding reading lenses in your unique prescription. You will be able to order glasses with clear prescription lenses or with tinted prescription sunglass lenses with anti-scratch, anti-UV, and / or anti-reflective coating. You will also have a choice of lens materials such as CR-39 plastic, polycarbonate, Trivex, or hi-index.Light rays passing through the optical center (OC) of a lens are not refracted. With proper PD measurements, your eyes are centered at the optical center of the lens. For taking your unique fitting measurements, your physical presence is absolutely necessary. We will need to pre-adjust the frame on your face before ordering your glasses. Light rays pass through what part of a lens without being refracted?

If there is a value under this heading, then you have astigmatism. Like sphere power, the cylinder power is also measured in diopters.Eyeglasses ordered under an insurance plan are usually processed by the insurance labs and we do not have much control over it. They usually take 5-10 business days. However, if you order your glasses privately (i.e. What is cylindrical power? If there is no value under the cylinder heading, then you have a simple prescription. If there is a value under this heading, then you have astigmatism. Like sphere power, the cylinder power is also measured in diopters.You need frame adjustment. Also consider lighter lenses such as hi-index or polycarbonate in a smaller frame.Both are equally effective. What is prismatic power? When the two eyes are not properly aligned and looking directly at the same thing, prism can be ground into the lenses in order to re-align them. This can occur with strabismus or in situations where the eyes are properly aligned but are under a tremendous amount of strain in order to keep them aligned. The value under the 'prism' heading of your prescription denotes the strength of the prism.Both are equally effective. It is your preference. Generally people match the color of transition lenses with the color of the The use of readymade reading glasses is perfectly safe but does not replace the need for regular eye exams. What do the numbers on the frames mean? Frames are identified by manufacturer / designer, model number or name, size, and color information. Size information contains the horizontal measurement of each lens in millimeters (i.e. 47) and bridge size (the distance between the lenses) i.e. 18. This information can help you in sizing a frame for your face. To better understand the frame size, double the first number and add the second. This will give you the distance across the full front of the frame.This is the main part of your prescription. This number denotes the strength of the lens as measured in diopters.
If you've reached the ripe young age of 40 then odds are you have trouble with your vision, specifically your near vision. You may even believe you brought this on yourself - maybe your mother was right when she said not to sit so close to the T.V. What has actually happened is that you have just joined about 135 Million other Americans in the Over 40 Club and your blurry near vision has nothing to do with your bad habits. It's just presbyopia! Presbyopia is actually blurry near vision due to a natural decrease in your eyes ability to focus. That's right, it's normal - it happens to everyone about age 40. Some have defined presbyopia as the shortening of the arms that prevent you from holding an object far enough away to be read. While this makes great comedy, it's not true. There's nothing you can do to stop it. Wives tales Would have you believe that wearing glasses make sit worse, the explanation is really simple. Inside each eye is a crystalline lens which is responsible for focusing our vision between distant and near objects. When a person looks far away the lens in the eye is relaxed, but when that person looks at something nearby, such as a book, the lens flexes to focus on the book. In our youth the lens, like us, is very flexible and active - it can focus on a distant mountain and seconds later read a book held 4 inches from our noses. Over time that lens, also like us, gets a little thicker around the middle and doesn't like to flex as much. At age 40, the lens becomes fat and lazy, because the lenses are not able to flex things like your watch become blurry. Even things at 40 centimeters, usual reading distance, are blurry. While this process takes four years to occur, it is at age 40 that we notice because we can no longer do things nearby that we used to be able to do. Because of this, a new lens like glasses lens or contact lens will be used to focus our dear vision. There are many great options to overcome this obstacle. Traditional bifocals, reading glass, progressive lenses, also known as no-line bifocals and bifocal contact lenses are just a few of the options available to you. cataract surgeons are using new implantable lenses that can be surgically inserted in place of your natural lenses. Monovision LASIK is also a great option. New and better technology becomes available each day and your local optometrist can share more information about the latest advances.
