As with most things, the history of contact lenses is debatable, as different accounts filter through as the years go by. Some say that as early as the 1500’s, Leonardo da Vinci made sketches depicting how the focus of the eye could be changed if the cornea was placed in water. Obviously, real contact lenses weren’t around until much, much later but this early story shows that the concept may have been. No one can know for sure the exact sequence of events that brought the contact lens into prominence, but the general timeline and history of contact lenses is agreed upon by most in the industry.

In 1827, a man named John Herschel may have made the first real contact lens suggestion. Herschel suggested that a lens should be developed to be placed over the eye to correct vision. He thought if a plastic mold of a typical eye were made, it would act as the perfect vehicle to have a proper lens created.

The first real contact lenses were produced somewhere around 1887 or 1888. The names of Germans FA Mueller, Adolf Fick and Edouard Kalt come up when discussion of the first contact lenses come up, but debate exists over which one or which combination were actually the ones who got the job done. Most likely, those first contact lenses were a far cry from the soft, comfortable contacts of today, but they were the beginning of the industry.

A man named Kevin Tuohy produced the first hard contact lenses in 1948. Hard contacts are also called rigid or gas permeable contact lenses, and generally allow more oxygen into the eye than today’s soft contact lenses. They are also less comfortable than soft contacts, and the hard contacts made in 1948 were probably even less so. The first soft contact lenses didn’t come along until 1959, and were invented by two Czechoslovakian chemists. The soft contacts were made of hydrogel and offered a comfortable alternative to hard lenses.

After those first hard and soft contact lenses were brought into the marketplace, more changes started to happen to get things where they are today. The first FDA approved soft contacts were introduced in the US in 1971. Over a period of a few years starting in 1979, new additions were added to the contact lens market to give wearers greater selection and versatility. In 1979, RGP contact lenses were introduced, with extended wear soft contacts shortly after in 1981. After that in 1982, bifocal contact lenses were introduced as an alternative to having to wear bifocal glasses. RGP extended wear contact lenses were brought into the marketplace sometime in 1986. In 1987, life became a whole lot easier for many contact lens wearers, as disposable soft contacts were introduced. 1 day acuvue lenses didn’t come out until 1995. The world of contact lenses will likely continue to change and evolve, as the history of these little medical devices is far from complete.

When you make a visit to your eye doctor for an exam to determine the nature of your vision problems, you may end up hearing the word astigmatism. Along with nearsightedness or myopia, and farsightedness or hyperopia, astigmatism is a common diagnosis that requires a prescription for glasses. With farsightedness, a patient has trouble seeing objects that are in close range, while with nearsightedness, objects in the distance are blurred or out of focus. When you have astigmatism, your vision is blurred at any distance, making the need for glasses even more important. Sometimes, people with nearsightedness or farsightedness can compensate, as one type of vision is still good, but with astigmatism that’s much more difficult.

Astigmatism occurs when the lens within your eye, or the cornea itself is curved or irregularly shaped. When this happens, the light that enters your eye can’t focus on the retina correctly and your vision is blurred. Astigmatism is a common condition that most people have to some degree. Smaller amounts of astigmatism don’t always require corrective glasses, but when it starts to affect your vision, glasses are a common remedy. Wearing glasses can help you see items both up close and far away with greater clarity. If you have astigmatism with blurred vision and don’t bother getting glasses, you may experience headaches and general eye discomfort in addition to the reduced vision. It isn’t uncommon for people to delay making the appointment because they don’t want to have to worry about glasses, but it’s usually well worth the effort.

Astigmatism is a condition that’s usually evident from birth, but can change as time rolls along. As a child grows, the astigmatism may get better or worse, and corrective glasses may be required. The only real way to know if you have astigmatism, or the degree is to make an appointment with your eye doctor. The doctor will measure how your eyes focus light and will figure out the power of the glasses you’re going to need to correct the issue. If you have astigmatism, a correctly prescribed pair of glasses can change the way the light enters your eye. Once this change, takes place, you’ll be able to see everything clearly.

If you have astigmatism, but really aren’t interested in wearing glasses, your doctor may suggest laser surgery as another option. Laser surgery isn’t possible for all types of astigmatism, but if it is for yours, the shape of your cornea will be changed to correct the problem. Small amounts of tissue are removed with the laser and your vision issue is corrected.

For those where surgery isn’t possible, mens glasses will make the correction. Astigmatism isn’t a horribly serious eye condition, but definitely one you’ll want to take seriously and get treatment for. Not being able to read the newspaper clearly may not be life threatening, but if you can’t read street signs clearly, you may end up in more serious trouble. It’s always a good idea to make an appointment with an eye doctor as soon and you notice any type of vision loss.

Choosing a pair of eye glasses can be a major decision for many women. Obviously, the proper prescription from your eye doctor is the most important factor and the reason you’re wearing eye glasses in the first place. However, after the prescription is taken care of and you can see clearly, several different factors come into play. It’s no secret that eye glasses are used as a fashion accessory by both sexes, but for women that connection may be even stronger.

Considering the circumstances that you’ll be wearing the glasses in is one factor for choosing the right pair. Many women pick out two or even three different styles of frames for eye glasses, just to suit the different facets of their lives. You may have a job in an office setting and run your kids around to soccer practices or dance classes in the evenings, then hit the town with friends a couple times per month. In each situation, you’ll wear different clothes, shoes, and possibly a different purse. Wearing different glasses to suit each circumstance helps to put the finishing touch on the whole outfit. Once you’ve determined how many different styles of eye glasses you may want, you can narrow it down further by following a few specific guidelines.

For a woman, matching a pair of eye glasses to your skin tone is a good first step. You don’t want to pick a pair of eyeglass frames that stand out like a sore thumb on your face, but you also don’t want to pick frames that just blend in and aren’t noticed at all. This is where enlisting the help of your optician is a good idea. She can suggest eye glasses that suit your skin tone the best, and will work best for each occasion. The shape of your face is another big consideration when choosing eye glasses for women.

It’s important to choose frames that balance the features of your face, rather than accentuating one particular feature. As an example, if your face is more of a square shape, choosing square lenses might not make sense. If your face is long, you’d want frames that work to shorten it up. Again, your optician will note the shape of your face and make suggestions to create balance in the overall look.

Once the look of the frames is right from an appearance and fashion standpoint, it’s time to tinker with the actual fit. Most pairs of cheap eyeglasses can be adjusted for a comfortable fit if they don’t fit the way you want. Your optician will look carefully as the glasses are on your face to determine if they are the proper width and sit on the spots they’re supposed to sit. You don’t want eye glasses that squeeze your nose or temples, and you don’t want eye glasses that slide off your nose or are too wide. Since you’re supposed to be wearing them to correct your vision, comfort is a big factor for each pair you buy.

Eye problems are common in people both young and old, and one of the more sinister is glaucoma. Glaucoma is a complex eye disease where elevated pressure within the eye can cause several different vision problems. Peripheral vision may be affected with glaucoma as the optic nerve suffers damage, and if it is left untreated a patient may even go blind. Elevated eye pressure is usually a sign, but even people with normal pressure can develop glaucoma. If you wear glasses already, you are at just as much risk for glaucoma as anyone else. There are two main types of glaucoma; one is called primary open angle glaucoma and one is called acute angle closure glaucoma.

If you suffer from primary open angle glaucoma, your symptoms may include the eventual loss of your peripheral vision in both eyes and severe tunnel vision. With acute angle closure glaucoma your symptoms may include severe pain in your eyes, nausea and vomiting with the pain, reddening eyes, halos around lights or blurred vision. Both types of glaucoma can be considered either primary or secondary conditions. If the condition is primary, it means a specific cause is unknown. If the glaucoma is secondary, it means the glaucoma can be traced to a specific situation like a tumor, eye injury, inflammation or diabetes.

Glaucoma will be diagnosed through an exam with your eye doctor, but he won’t prescribe glasses to treat the condition. Glasses are of no use when it comes to treating glaucoma, but you may need them if another eye issue is detected. If you suffer from astigmatism, nearsightedness or farsightedness, your doctor may have you wear corrective glasses to help. As far as glaucoma goes, the treatment will depend on the stage of the disease. You may be prescribed eye drops designed to lower your pressure, or you may require surgery to get the job done. Either way, the pressure in your eyes must be lowered to maintain your sight over the long term.

If you already wear glasses, you’ll still have to wear them after your glaucoma diagnosis. The glasses you wear everyday were prescribed for your particular eye issue, and it will still be there after glaucoma is discovered. If your original vision problem has worsened, you may need some new glasses with a new prescription to keep your vision clear, but new glasses won’t have anything to do with glaucoma specifically.

With glaucoma or any other eye issue, it’s always wise to make an appointment for an eye exam when you first start exhibiting symptoms. Many eye problems will require you to get eyeglasses, but with glaucoma a quick exam is just as important. Glaucoma is manageable if it’s detected early enough, and although it can’t be cured entirely at this time, you will be able to preserve your vision. A thorough eye exam will also help the doctor see if you need some new glasses or your first pair of glasses.

Depending on the condition of your eyesight, you may end up seeing a range of different doctors before your issues are completely settled. Not all eye problems are as straightforward as getting a new pair of eyeglasses or contact lenses. Sometimes, the issue goes a little deeper and some more expert help is required. If you just need a basic exam and prescription for eyeglasses, an optometrist will be able to handle your needs. However, if you require a more comprehensive treatment, you may be directed to an ophthalmologist.

An ophthalmologist is an eye doctor that is a specialist in the treatment of the entire vision system. Ophthalmologists are often called in when a patient needs more than just eyeglasses. Sometimes, surgery may be necessary as an underlying injury or eye disease is causing the eye problems. Ophthalmologists are perfectly capable of doing routine eye exams and prescribing eyeglasses to patients, their expertise just goes farther than a standard eye doctor. An opthamologist may be a doctor of medicine, characterized by the ‘MD’ abbreviation, or a doctor of osteopathy, which is characterized by a ‘DO’. In either case, extensive schooling is required in order to gain the knowledge and certification to do the job.

The range of care an Ophthalmologist is qualified to give covers basically everything eye care-related. Basic vision services such as eye exams and issuing eyeglasses are one of the services provided by an Ophthalmologist. Other types of eye doctors can also prescribe eyeglasses, but it is still an important service that must be provided. Wearing the wrong eyeglasses for even minor vision problems can make some conditions even worse and cause a host of different symptoms. Moving on from basic treatments, an Ophthalmologist is skilled in the medical side of eye care, which includes glaucoma, chemical burns and other conditions. These issues may or may not include eyeglasses in any way. Surgical eye care is another that falls under an Ophthalmologist’s expertise. Problems like cataracts, tumors or crossed eyes may require surgery that an Ophthalmologist is able to perform.

Eye problems that are the result of another disease or condition are also sent to an Ophthalmologist. These may include diabetes, multiple sclerosis or issues that stem from arthritis. Generally, eyeglasses will be prescribed to help correct a disease-related vision problem, but that prescription may have to be altered after surgery. If vision is restored to normal from the surgery, the need for eyeglasses may no longer be necessary. Some Ophthalmologists will even tackle plastic surgery that deals with the eyes.

Skin tumors, droopy eyelids and general wrinkly skin around the eyes are some of the plastic surgeries an ophthalmologist may treat. Plastic surgery won’t affect your prescription for cheap glasses in any way, but you may end up wanting to ditch the glasses for contacts if you’re more pleased with your appearance. Tightening up the skin around your eyes can take years off your appearance, and eyeglasses might hide the work that has been done.
