How Do You Know If You Need Glasses?

Knowing whether or not you need glasses may sound like a very simple thing to figure out, but it could be a bit more difficult than you might think. Your eyesight may be degenerating very slowly, so slowly that you grow accustomed to how you view things and never even know that any change has taken place. Some common symptoms that will let you know that you may need glasses are: your sensitivity to light, unexplainable headaches and overly "tired eyes".

If you go from a room that is dark into an area of light and you find that it takes your vision an exceedingly long period to recover from the change, or if you see "halos" or have other inconsistencies in your vision while its adjusting it may be a sign that your vision needs some correction.

If you seem to be suffering from frequent headaches or migraines that dont seem to have any association with allergies, illness any other form of injury or ailment it could mean that you need to have corrective lenses to help your vision. Extended periods of over exertion by the eyes, trying to compensate for weakened vision can lead to frequent headaches.

If your eyes themselves feel weak and tired in what seems to be a shorter time period after participating in things like reading or viewing a computer screen, it could be time to have your eyes examined to see if corrective lenses might be the answer to your problem.

Most people dont follow the prerequisite suggestion of having their eyes examined by a professional at least once every two years. Visiting a qualified optometrist is really the only accurate way to determine if you need any level of vision correction and what course of action may be necessary in order to get you seeing properly again. Many people wait until its difficult for them to see something that is directly in front of their face before they bother making an appointment with a qualified eye care profession, and then they seems surprised by just how bad their vision is.

The truth of the matter is that far more people walking around need glasses or sometime of correction than actually have any. For some its the desire to remain free from the shackles of glasses and contacts for others its the fact that theyve lived with their vision problems for so long that they truly believe that how they are seeing is normal and dont feel that they need vision correction.

There are a number of reasons that visiting your eye care professional is of the utmost importance. Firstly, knowing that you have a vision problem and taking the steps to have it corrected could be crucial to your survival - be able to see clearly and be able to react promptly while doing one of lifes most common activities, driving, could literally spell the difference between life and death - you need to be able to quickly identify all traffic signs and signals while traveling in order to be the safest driver that you can be, and its very difficult to do that with poor vision.

Having your vision problems corrected with glasses could also do wonders for your health. Not having to labor to see every little thing will result in less headaches, less migraines, less back and neck aches plus have you feeling more alert and awake overall. Your performance will most likely improve at work as well as is any hobbies you enjoy that require fine detail.

Properly identifying vision problems on your own is impossible, in order to really know if you need glasses its necessary to have an exam at the office of an eye care professional. Even if you had no problems when you visited the optician at an appointment three years ago, that doesnt necessarily mean that your eyes are problem free today, regardless of how well you believe that you see if its been more than two years since your last eye exam you should schedule one soon to be safe.

How do Bifocal Contact Lenses Work?

Posted on by

Bifocal Lenses Bifocal lenses are commonly known as eyeglasses that correct two different vision problems. More specifically, they help clarify vision in two viewing zones - a near one and a far one. Simply put, bifocal lenses have a section you look through to see objects that are up close more clearly and a section that you look through to see objects that are at a greater distance more clearly. Bifocal lenses are typically prescribed for patients who are diagnosed with presbyopia.

Bifocal lenses were invented by Benjamin Franklin. He constructed the very first pair of bifocals with convex lenses in the lower half of the eyeglass frame and less convex lenses in the upper half. These original bifocal lenses contained a line that spanned the entire width of the lens. At the beginning of the 20th century, bifocal lenses saw improvements such as the smaller, half-moon shaped bifocal segment.

If you have been diagnosed for presbyopia, you may think that bifocal eyeglasses are your only option. You may have worn bifocals for many years and may be used to them. Whether you are ready for a change or you have just recently discovered that you have presbyopia, youll be glad to know that there are contact lens versions of bifocal lenses currently available on the market.

Bifocal Contact Lenses Bifocal contacts, similarly to bifocal eyeglasses, simply contain two prescription strengths within the same lens. Many times bifocal contact lenses are referred to as multifocal contact lenses. Below is an explanation of how bifocal contact lenses work.

Alternating Bifocal Contact Lenses Alternating bifocal contact lenses are also referred to as "translating bifocals." This version of the multifocal contact lens is the most similar to traditional bifocal eyewear. Alternating bifocal contacts contain two fields of strength with a clear definition between the two. The division is generally a horizontal one along the middle of the lens with distance vision correction in the top segment and near vision correction in the lower segment.

With bifocal eyeglasses, the method works because the lenses always stay in place, even as your pupils shift downward or upward. Contact lenses, especially soft ones generally move with your pupils somewhat - so how do alternating bifocal contact lenses work? The answer is simple. Most alternating bifocal contact lenses are gas permeable lenses. Gas permeable lenses are smaller in diameter than soft contact lenses and they ride up on your eye in order to rest on or above your lower eyelid. Because of this, when your pupil shifts downward, the lens stays put so that you can see through the lower half of the lens where the near vision correction strength is.

Are Bifocal Contact Lenses Right for Me? Just like anything else, bifocal contact lenses may not work for everyone. In fact, until recent years, bifocal contacts werent very popular because many people found them uncomfortable and unsatisfactory. The good news is that today, new technology has produced a higher quality bifocal contact lens that is more comfortable and easier to use. Technology has also lent itself to provide a much greater variety of designs to suit almost any user. Furthermore, eye care professionals have become more creative in their uses of bifocal contact lenses for vision correction and treatment of presbyopia. Of course, which bifocal contact lenses are right for you is a decision that will be made jointly by you and your eye doctor. Now that you know more about bifocal contact lenses, make sure to ask your doctor about all the different types of bifocal contact lens treatments that are available to treat your specific vision problem.
