Are Contact Lenses Better Than Eyeglasses?

By Paul Cris

Contact lenses float on the surface of eye. There are two types of contact lenses, soft lenses and hard lenses. Soft lenses are made of very soft water soluble materials, which take the shape of the eye when worn. You can also get disposable soft contact lenses in the market. We can change these disposable lenses daily, after two weeks or once in a month depending on the brand and material.

Hard lenses are produced from hard gas-permeable plastic and it covers only part of the cornea. Today colored lenses are also available.

Contact lenses are better than eyeglasses for certain vision disorders like shortsightedness, long-sightedness, astigmatism and presbyopia. In the field of sports people prefer it because eyeglasses are hard to handle. Some prefer it for its wider view. Eyeglasses don’t cover the sides. Temperature, rain or perspiration does not affect contact lenses. And lastly people buy contact lenses for the feel and look good factor. It is a fact that eyeglasses do not look good on many peoples faces.

But contact lenses also have disadvantages such as:

1. The eye becomes drier than normal
2. Risks of eye allergy increase if the contact lenses are not handled properly.
3. It is not good for people with conditions such as diabetes.

Hence we can safely say that it is the condition that decides whether eyeglasses or contact lenses are better. It also depends on the user’s personal choice.

Is it Wise to Buy Discount Eyeglasses On-line?

By Tim Gorman

Should you buy discount eyeglasses? Comparison shopping and buying on-line is now a major trend, where a lot of people shop for clothes, medicine, insurance, cars and eyeglass. But is it wise to compromise the health and condition of your eyes, for a pair of discount eyeglasses?

Although it may seem to be a safe and ordinary part of the process to fit for your eyeglasses, this is not true.

For the optical center of your eyeglass lenses is the part that gives you clear vision, and determining where to put these lenses forms an important part of the work of an optician. Surf discount eyeglasses websites and you will discover that they need to determine this distance between your eyes or PD. For this, you’ll still need to get fitted by your optometrist or the lab, to have this correctly determined.

You may end up selecting the wrong frame for your face and all because it’s a pair of discount eyeglasses. Having the proper frame for your eyes is important because if they fit properly you won’t have headaches, and you see clearly.

Frames that are too large or don’t fit your face properly will fall of your nose. If this is too small, you’ll feel uncomfortable, as they will pinch the bridge of your nose. Either way, if they aren’t the right size for you, you’ll end up owning a useless pair of discount eyeglasses.

Another important factor you should consider, how can you determine if you look good in a pair of discount eyeglasses? Isn’t it more satisfying to be able to try on any pair of eyeglasses you see in the optometrist clinic and immediately know if this pair suits you? Something you can’t do with discount eyeglasses, even if online shops try to approximate it with flash programs.

Weigh your options and if you can spend a little bit more to have it this done in the traditional way, at your optometrist clinic, then do it.

This may sound trite, but you have only one pair of eyes, and you should do all you can to protect and keep this pair healthy, so they’ll serve you better.

How Long Have Prescription Eyeglasses Been Around?

By Tim Gorman

From documents that were retrieved in Rome in the 13th Century, we know that prescription eyeglasses were available at that time. They were referred to as "spectacles" rather than glasses. Although we do not know for certain when prescription eyeglasses were invented, we do have proof that they did exist during this time period. A portrait done by an artist named Tomas da Modeno portrays a gentleman wearing eyeglasses. Obviously what we do not know is if they are prescription eyeglasses. There are, however, other documents such as a manuscript written by a man that implies that if the he wasn't wearing spectacles, he would not be able to read or write.

In the 15th century the printing press was invented which meant more reading material was readily available. Thus, the need for prescription glasses increased. The first reading glasses were held by one hand only during the times that they were needed for reading. It was later in the 17th century when people actually wore the glasses regularly, after an optometrist created them with both earpieces. In those times, a person who was having difficulty with their eyesight would just go in and try on several pairs of prescription eyeglasses until they found a fit for their needs. That changed when Dr. FC Donders wrote the first book on examining the eyes to get prescription eyeglasses.

Benjamin Franklin is credited for the invention of the bifocal lens. With a bifocal lens the bottom half is used for reading and the top half is for seeing objects that re further in the distance.

The first lenses in the prescription eyeglasses were made from quartz crystal and very low in quality and durability. Then in the early 1900's, Bausch and Lomb created the glass lens. Today most prescription eyeglasses are made from a plastic material that can be polished and tinted like glass lenses. The advantage to the plastic lens is the lighter weight of the prescription eyeglasses as well as the durability is greatly increased.

Take Care Of Your Eyes Using Eyeglasses

By Naresh Kumar

Many of us are fond of driving bikes. While driving the bike we must wear eyeglasses for the safety of our eyes. There are many different small particles of stones, dust, and chemical pollutants that emerge from factories, always present in the environment.

When people drive the bike, the speed of bike is normally averaging between 60-80 km/hr and even more. Imagine what will happen if a small dust particle hit our eyes at speed of 60-80 km/hr. It may damage our eyes. Sometimes it may make us blind. So I request all people to wear eyeglasses with strong lens material while driving your motorbike.

One other use of Eyeglasses is in sunshine. Many people find direct sunlight to bright to be comfortable. This specially occurs while people take sunbath in beach or try to read new paper in sunshine. There are many such outdoor activities in which people find sunlight is more than usual. It has been recommended to always wear the sunglasses in strong sunshine to protect eyes from ultraviolet ray, which can lead the development for cataract in eyes. Sunglasses have colored lenses, which prevents strong light from reaching our eyes.

One other use of eyeglasses for safety comes while working in front of the computers. If we work long hours of day in front of the computer, then at the end of the day we feel tiredness and sometimes pain in our eyes. Wearing anti-glare eyeglasses reduce the tiredness and pain even if we work in front of computers for long hours.

Anti glare eyeglasses or less glare eyeglasses are also useful while driving in night.

Contact Glasses

By Jennifer Bailey

Among the high number of people suffering from nearsighted vision, there are going to be people who do not want to wear eyeglasses. Perhaps they do not find them comfortable, or they feel that it does not make them look attractive. For these individuals, the use of contact lenses is the option they wish to pursue.

If you want to wear contact lenses, you must first see an eye doctor. This is because contact lenses have to be fitted to the shape of your eye. In fact, in the United States you may only be allowed to purchase contact lenses with a valid prescription from an ophthalmologist, optometrist, or optician. Eye doctors will first need to check whether your eyes can handle contact lenses. The majority of people today are able to wear contact lenses, but there are the rare few that would not be able to.

The reason some people choose to wear contact lenses over eyeglasses is the fact that contact lenses offer closer to natural sight than eyeglasses. The also offer better peripheral vision over eyeglasses. The convenience and flexibility contact lenses offer is the reason most people decide to wear them.

With contact lenses, you are able to participate in activities you would not be able to when wearing eyeglasses. People who participate in athletic sports can attest to the inconvenience of having to wear eyeglasses while participating in sports. For these individuals contact lenses are ideal for their lifestyle. Contact lenses will not steam up from perspiration, or get foggy when you move from cold to warm temperatures. Because of this many people find it more practical to wear contact lenses instead of eyeglasses.

If you prefer the way you look without eyeglasses or participate in activities where it would be inconvenient to wear eyeglasses, then you should consider wearing contact lenses.

Different Types of Eye Disorders

By Tim Gorman

The need for prescription eyeglasses could come from many different eye conditions. The most common eye disorders are Farsightedness, Nearsightedness and Presbyopia.

Nearsightedness, otherwise known as Myopia, is the most common eye disorder. It occurs when light focuses in front of the retina rather than focusing on the retina. The symptoms for Myopia are blurred vision on objects that are in the distance. Squinting the eye will actually make the object clearer. Vision can be corrected with prescription eyeglasses with either a bifocal or trifocal lens.

Farsightedness, or Hyperopia, is just the opposite of Myopia. The light focuses behind the retina instead of in front of the retina. One common symptom of Hyperopia is headaches or the eyes will become tired from reading. It is difficult to see objects that are within close range. In children, the most common symptom is crossed eyes. Again this eye disorder, too, can be corrected by wearing prescription eyeglasses.

Presbyopia is another type of eye condition that can be corrected with prescription eyeglasses. This disorder is where the eye's lens cannot focus. This usually happens to everyone in his or her late forties. The symptoms for Presbyopia are that a person finds himself or herself holding reading material farther away to enable reading. Also, eye fatigue is a common symptom.

The importance of getting regular eye exams to check for these eye conditions can't be overstated. Left untreated, all of these conditions will only worsen.

In a routine eye exam the optometrist will also do a glaucoma test. Glaucoma is the build up of fluid on the eye that results in pressure on the retina. It is irreversible if left untreated, and can cause total loss of sight. This is one eye disorder that cannot be treated by wearing prescription eyeglasses. However, this condition rarely has symptoms, therefore stressing the importance of routine eye exams.
