Coloured Contact Lenses

Do you have trouble seeing up close? it is possible you have hyperopia. But it could also be presbyopia. The truth is they are similar optically but have very different causes. Because they are foundationally different, their treatment options will also vary.

Hyperopia occurs when the light that enters the eye can not focus on the retina, because the eye is to short, the light actually would focus behind the eye. This is caused when the eyeball is shorter than it should be. Hyperopia, similar to myopia, can occur at any age. Some childred will actually outgrow this condition, as they grow, so do their eyes. But if they do not, corrective lenses such as contacts of eyeglasses can be used to treat hyperopia. For low power hyperopes a set of reading glasses can correct vision. Corrective laser surgery is also an available solution.

On the other hand, presbyopia also causes people to have diffculty seeing at near, but is age related. It is caused by the lens inside the eye losing flexibility. The result is the same as hyperopia: poor near vision. In general, corrective lenses are used to fix this. reading eyeglasses , used to clarify objects up close such as text or computer screens, are commonly used. Another choice is contact lenses to produce monovision, when one lens corrects the distance vision, if needed, and the other lens corrects the near vision. Monivision users have to train themselves to see through this new optical system. Contact lenses come in a multifocal variety, correcting vision similar to progressive eyeglasses.

Hyperopia only effects some and it is possible to treat it with surgery. the condition of presbyopia is inevitable, and until recently, was not generally treated with surgery. When the lens inside the eye loses its ability to flex and adjust focus, seeing up close is extremely difficult, that is when it is time for treatment. Though surgery for presbyopia has become available, the overwhelming majority of sufferers still choose the option of wearing reading glasses. They are safe, they do not require an invasive procedure, and they are stylish. If you are suffering from presbyopia and you need to wear readers, you may as well find a pair that looks good too.

Unbelievably, in the old days, a person’s reading eyeglasses’ strength was only a function of that person’s age. A middle aged man would be issued glasses with a strength of 2 degrees and a person of more advanced years offered a 4 degrees of strength pair of specs. Around the middle of the 1800s glasses were being sold by knowledgeable students of optics.

It’s crazy that in the 21st century, people still choose to pick out the most convenient set of reading glasses by trying them on at the local store.

Despite the works from Airy on the cylindrical correcting lens in the early 1800’s and Donders brilliant work concerning refraction later that century, it was only in the late 19th century that people were starting to correct their patient’s astigmatisms. Many inventive solutions come out of necessity and it was the same for bifocal lenses. Benjamin Franklin – yes THE Benjamin Franklin, needed to devise bifocal lenses for himself and so he split apart the lenses in his reading and distance eyeglasses and just stuck them together – Hey Presto: Bifocals were invented.

Hawkins introduced trifocal lenses in 1826. It was only in the 1960’s that manufacturers produced smoothly increasing powers in a better range of multifocal lenses. Unfortunately, these lenses are such a compromise in optical terms, and the field of clear vision in the reading area is so small that, for even the short lines of print when it is in double columns, the reader is obliged to turn his head slightly to follow along each line.

Multifocal lenses have their best chance of acceptance if introduced when presbyopia first appears as then the necessary increases in strength with age are more readily tolerated.

You may find the history of spectacles interesting as I do. I would advise you to really study specs and their beginnings to help you better appreciate what a wonderful device they truly are. If you are going to buy eyeglasses online, please ensure that you buy them from somebody who is sufficiently trained and interested in the subject and your eyes.

Match your eye glasses to your personality

In this competitive world of ours, image is everything. And even if you don’t think of yourself as being ‘image-oriented’ deeper insight into your personality might lead to startling revelations. Either way, when it comes to choosing eyeglasses, it’ll be worth your time to look for a style that fits your personality.

That’s not to say that if you’re feeling blue, you should opt for blue-colored frames or lenses. What it means is that before you head over to the ‘discounted frame’ section, you need to stop and think about who you are and how you live.

Are you older, younger or somewhere in between? Do you consider yourself to be trendy or conservative? Do you have a career or are you a student? What is your career or your area of study? Are you driven by name brands or do names not impress you? Do you look at eyeglasses as a fashion accessory or a necessary evil?

If you’ve answered these questions, you might wonder, ‘Now what? So what if I’m days away from becoming a Baby Boomer and I work a desk job? How is this going to help me choose an eyeglass style?’

Well, one solution is to discuss these self-analysis results with your optician so that together you can work towards finding a suitable pair. A good optician will know which styles are ‘in’ and which are finally on their way ‘out’. He or she may also be familiar with matching eyeglass shapes, styles and coloring to face shapes, much in the same way as a hairdresser can usually recommend a flattering hairstyle.

Plus an experienced optician will know the inventory well. He or she will know how long a particular pair will take to order, about the materials used in each of the various manufacturing processes and whether they’re durable or delicate, about the total costs involved from start to finish for the various styles, and other types of useful information that you may not have thought about.

But if you’re still confused as to which eyeglass style will best match your personality, here are a few more tips.

If you run in conservative circles, stick with conservative styles and colors. Neutral colors including brown, gray and silver and standard lens shapes such as rectangles and ovals are good choices.

If you prefer to be the center of attention, then choose eye glass styles that will get noticed. Look for unusual shapes and bold colors. If the price is right, get several pairs so you can mix and match with your wardrobe and other accessories.

If you like trends but want a style that has staying power, look at the newest materials being used for eyeglasses such as titanium, stainless steel and memory-metal.

Students and those with a creative or artistic flair look best in styles that help express their individuality. There are no rules here except to steer clear of ‘traditional’ styles.

Choose specialty styles if you need eyeglasses for a specific purpose such as working at a computer, eye protection, sports and hobbies or driving.
