Eyeglasses can now be sold separately in either frames or lenses and there are many replaceable lenses and frames as a result. However, it seems that lenses are much popular than frames, for many people love to fix the same frames with different lenses. Among so many replaceable lenses, transitions lenses, also called photochormic lenses or transition photochromic lenses, are very popular, mainly because buyers posses special passion for them.

 

Transition lenses in different colors are available in the market. There are usually grey, black, green, brown, yellow and other colored transition eyeglass lenses. This can really satisfy buyers with different color demands. However, some people may have such question that is there any difference among transition lenses in different color; are light tinted lenses worse than dark tinted lenses in terms of vision protection, and so on. Such worries are reasonable but not necessary. There are no difference among all lenses in terms of function and vision safety, no matter what the color are and how dark or light the color is. Therefore, people can choose transition lens of any colors according to their personal tastes.

 

Transitions lenses  in the market can be made from various sorts of materials and can meet buyers’ different needs. Glass, plastic, polycarbonate and other new materials in the industry are widely employed to manufacture these lenses. And the only difference among transition lenses from different materials is cost. Usually, these lenses made from ordinary materials are cheap while those from the latest materials are expensive. And buyers can buy the lenses that fit them most according to their personal income.

 

There are also many transition eyeglass lenses that can be used to rectify different vision errors. Usually, these lenses are compatible with many other lenses. For example, there are many special transition lenses for presbyopia, like transition bifocals, transition trifocals, and so on. Therefore, these lenses are suitable for all people whether or not they have vision errors.

 

By and large, transitions lens can be fallen into two major groups, say, common lens and sunglass lens. The former is ideal for daily uses, especially in other reasons, not summer; the later is very good option for people who are in need of sunglasses in summer. Therefore, if fixed onto different frames, they can be called transition glasses and transition sunglasses respectively.

Choosing Eyeglass Lenses in Glassesshop

Sunday, July 3rd, 2011

Buying eyeglass lenses requires making decisions about the design of the lenses, the lens material, and any coatings you may want applied to the lens. A good place to start is an overview of eyeglass lens options, and then you can choose your favorite glasses on the homepage of Glassesshop.

Lens Designs

Lens design is a decision that’s probably made for you. Most people get either single-vision lenses (to correct nearsightedness, for example) or bifocal lenses. Bifocals and other multifocals correct more than one vision problem, such as nearsightedness and presbyopia (an age-related inability to focus on close work).

Many people who require bifocals or multifocals opt for progressive lenses which have a smooth progression of optical power, enabling you to see at intermediate distances as well as near and far. Another advantage is that they don’t have bifocal lines, which can be unattractive and a tell-tale sign of age! Still others prefer reading glasses; the market has grown in leaps and bounds now that baby-boomers are wearing them and a wide variety of styles is available.

For those with double vision, a special prism in eyeglasses may be necessary. This lens enables light to be bent or reflected in certain ways and can also split white light into different wave lengths and colors, correcting the problem.

Lens Materials

Three factors will drive your decision on eyeglass lens materials: appearance, function and safety.

To look good, you’ll want your lenses as thin as possible. An excellent choice is high-index lenses. People with strong prescriptions love them because not only do they get rid of the hated “Coke-bottle” appearance, but they’re also lighter to wear. No more sore on nose!

Tired of the hassle of switching between your prescription eyeglasses and your sunglasses? Maybe you wrestle with sunglass clip-ons instead. You might want to look into photochromic lenses, which automatically darken when you step outside and return to normal when you go back indoors. If you think they don’t work quickly enough, you’ll be happily surprised to learn that today’s photochromic lenses work more quickly than the ones in years ago.

When safety is an issue, you must use polycarbonate—an extremely impact-resistant material. It is ideal for sports and kids’ eyeglasses. The American Academy of Ophthalmology has information about the best ways to prevent eye injuries during sports. You can also get information from Prevent Blindness America.

Lens Coatings

Lens coatings are useful for fashion and/or function. Anti-reflective coatings are for both fashion and function: they help you to see through the lenses better and keep glare from obscuring your beautiful eyes from others. Scratch-resistant coatings are particularly handy for plastic lenses: while plastic is nice and light, it’s more scratch-prone than glass. UV coating protects your eyes from the sun’s harmful rays; you can get UV protection in both tinted and clear lenses. Fashionable mirror coatings come in many colors and prevent people from seeing your eyes.

Eyeglasses: What You Should Know About Lens Coatings

Saturday, July 2nd, 2011

Although always a optional extra, lens coatings are usually recommended in order to ensure the preservation of your new prescription lenses and that they provide you with the highest protection possible. As always, an informed shopper is an empowered shopper, so here’s the lowdown on lens coatings so that you can decide exactly what you need when buying your new eyeglasses.

Anti-Scratch Coating: The main aim of this coating is to protect your lenses for increased longevity. No eyeglasses will ever be completely scratch-proof but when lenses are treated on either side with a clear and hard coating, their longevity and resistance to scratches increases. This type of coating provides more protection against misuse but if you choose this option, do not think that your glasses are fully protected. Always put your glasses a hard clam shell case when you’re not using them and only clean them with the microfiber cloth.

The UV Protective Coating protects your eyes against the sun’s harmful ultra violet rays. Overexposure to the sun increases vision problems including the development of cataract. This coating acts as a sunscreen for your eyeglass lenses, which in turn will cover and protect your eyes without affecting the look of of the lenses at all.. Some eyeglass materials, such as polycarbonate, photochromic, and most high-index plastic lenses, have 100 percent UV protection built-in, so an extra lens treatment is not required for these lenses.

If you need to reduce glare, Premium Anti-Reflective Coating is recommended for night driving and computer usage. The coating is done in layers, with each layer specifically calculated to block reflected light. These coatings sometimes have a hint of green or purple coloring because of the layering effect. Reflections are eliminated and eyeglass lenses look thinner or non-existent, making your eyes more visible for better eye contact with others. Anyone being photographed or seen on camera would benefit greatly from such a coating.

Most premium anti-reflective coatings include a “hydrophobic” surface layer that prevents water spots from forming and makes the lenses easier to clean but beware – some solvents may harm the lens coating.

Photochromic lenses, otherwise known as their commercial term “Transitions” lenses, are specialized light adjusting lenses. While not generally available in Polycarbonate and in 1.74 high index lenses, they are a fantastic option because they adapt and transition into sunglasses when outside and back into regular eyeglasses with clear lenses indoors – all with the purpose of protecting your eyes again UV rays.

Finally, color tint lenses are generally used for sunglasses and are specifically manufactured with lenses that protect against sun but not against ultra violet light. They are great for people with light sensitivity or people who want sunglasses. These can either be bought with a non-prescription lens and worn in addition to contact lenses; or bought with prescription lenses placed in a pair of glasses frames so that your sunglasses are also a full optical tool. Should you choose this option, make sure you have an anti-glare coating placed on the inside of the lens and a UV protective coating surrounding the lens for optimum protection.

So, there you have it! Five coatings all summed up for you so that you can buy glasses that really work for you and include all the extras that fit your individual needs.

How Do Transition Glasses Work?

Friday, July 1st, 2011

Many drivers would wear sunglasses when they are driving so as to block strong sunlight, so would they do when driving in snowy day so as to keep off glare. Sunglasses, at those times, serve as a great help for them to keep eye health and to eliminate unnecessary car accidents. However, when the cars are driven from bright places to dark places, like tunnels, sunglasses would be burden some which would bring drivers side effect to see vision forward clearly. If drivers constantly putting on and taking off sunglasses, it would be fairly inconvenient for them and be rather dangerous. Then how to liberate drivers from this trouble? Wearing transition glasses would be helpful.

 

Transition glasses are special eyewears which appear to be regular eyeglasses in normal circumstances, but would turn to shades when encountering strong light, like sunlight, glare and any reflection. It is amazing, right? Then you must ask how do transition glasses work? How would they exchange color accordingly?

 

The myth of transition glasses lies in the lenses, which are made from photochromics glass. During the production of photochromics glass, elements sensitive to light, like argentic chloride and silver halide, etc., are mixed in. A small amount of copperoxide catalyst are added as well. When silver halide, meeting with light, would have chemical decomposition, during which process, many black silver micelles would be produced and distributed evenly on the glass. As a result, the glass turn to black. When brought to dark places, with the promotion of copperoxide catalyst, silver and halogen would get chemical combined once more, as a result of which the glass return back to be transparent again. This is how the magic come from. The decomposition and chemical combination can carry through for limitless times.

 

The photochromics glass, besides applied in eyeglass production, are used in many other fields, for example the production of windows. Houses or cars equipped with photochromics glass need no curtains to block sunlight, for in sunny days, the windows would automatically turn black and when envenfall comes or when in cloudy days, the windows get back to transparency.

 

Therefore, with transition eyeglasses, life are full of miracles and fantasy. Additionally, transition glasses are able to absorb UV, which is fairly good for eyes. They can be among eye wears of top grade.

Advantages of Progressive Lenses Over Bifocals and Trifocals

Wednesday, June 29th, 2011

Progressive lenses also provide a more natural correction of presbyopia than bifocal or trifocal prescription eyeglasses. Instead of providing just two or three lens powers like bifocals or trifocals, progressive lenses are true “multifocal” lenses that provide a seamless progression of many lens powers for all viewing distances.

With progressive lenses, you can look up to see clearly across the room and in the distance. You can also look ahead to view your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably.

And it’s easy to adapt to today’s modern progressive lenses.

And progressive lenses eliminate an annoying problem caused by bifocal and trifocal lenses known as “image jump.” With conventional bifocals and trifocals, images seem to “jump” as your eyes move past the sharply defined boundary between the distance and near parts of the lens. With progressive lenses, the transition between lens powers within the lens is smooth and seamless, letting you change focus from distance to near and back again more comfortably.

Choosing the Right Progressive Lenses for Your Eyeglass Frames and Visual Needs

For all powers of progressive lenses to fit within a pair of eyeglasses, frames in the past had to be relatively large.

If the frame was too small, the reading portion of the lens would sometimes end up uncomfortably small after the lens was cut to size and inserted in the frame.

But lens manufacturers have overcome this problem by introducing “short corridor” progressive lenses with compact designs that provide larger reading zones for today’s smaller, fashionable frames.

The popularity of progressive lenses has exploded in recent years, making progressives the most widely purchased lenses for correcting presbyopia. Our Progressive Eyeglasses are available in a wide variety of materials, including regular Progressive, Polycarbonate, polarized and Photochromic progressive.

Importance of Good Sight for Safe Driving

Monday, June 27th, 2011

We live in an age where getting from one place to another has never been easier. Need to pick up something from the store? Hop into your car. Need to visit a sick friend? No, problem, your car will get you there. Need to move stuff from one area to another? Again – those four wheels on your automobile is the way to go.

However, in order to drive safely and properly, one needs perfect eyesight and the ability to reflexively prevent a possible accident. Day driving presents dangers such as glares from the sun; while driving at night is especially dangerous. It requires special visual attention and focus owing to the glare of lights against the darkness, not to mention the darkness itself. At night, ones pupils dilate and even the best sighted people become short-sighted, and tend to see more glare and halos.

One also seems to have less peripheral vision. All these factors together result in visual fatigue and as statistics prove, even though night driving actually occurs less than day driving – both in time driven and in the amount of drivers on the road – close to half of road deaths occur while at night. In both cases, many deaths occur because drivers claim to to have been faces by a harsh glare that prevented them from seeing clearly.

So, what is the answer to protecting our eyes in both conditions?

First, one must wear sunglasses during the day – whether prescription or non-prescription. Aside from protecting ones eyes against harmful AVA/UVB rays, sunglasses should also include an anti-reflective coating to protect ones eyes from glares. The color lens also helps to enhance the visibility of contrast and depth perception, which ensures sharper visuals, less haze, and all round clarity.

For people who wear eyeglasses and cannot think of constantly having to swap their regular prescription eyeglasses for prescription sunglasses whenever going out, they can have photochromic lenses fitted into the frames. These lenses play the same role as sunglasses by turning dark outdoors and returning to regular lenses indoors, but you must check that they have been coated with the appropriate anti-glare protection.

Note: Following surgery, patients need to be extra vigilant while driving as the operation could result in seeing a halo effect – especially at night. Others may find that eye surgery drastically improves their night driving ability. In the end, each case is individual and should be viewed and treated according to its specific needs.

If you already wear prescription eyeglasses, a thorough eye examination may prove that you actually need separate, stronger lenses for night driving. If this is diagnosed, immediately purchase the new eyeglasses and ensure to have them coated with anti-glare protection. You should ALWAYS wear these glasses for night driving, without them you are a danger to yourself and others while on the road. If you do not generally wear glasses, you may want to buy eyeglasses with placebo lenses, but coated with the anti-glare tint. One of the most important points to remember when you buy glasses for driving is that cheap eyeglasses may be just that – cheap – so invest in a high quality pair of glasses frames.

Poor vision is actually a normal way of life for many people. Usually, some people have the symptoms of poor vision and do not even know it. One of the symptoms is a headache. If you ever begin to feel a headache coming on, you should immediately make and appointment to get your eyes checked by a doctor. Do not let your eye problems develop further than they need to. Your eyes are an important part of your life, your window to the world. You don’t want lose sight of the world around you.

However, it is important to know the symptoms that you need an eye check up. The most tell-tale sign is blurry vision and headaches. Oftentimes, you may think that you’re getting the flue or a common cold, but it the blurry vision and headaches last for longer than two days, you should immediately see a doctor about your symptoms. Because of the seriousness of these symptoms, you may need a pair of prescription glasses after you get your checkup from the doctor.

But for those of you in great health, especially eye health, you should still make sure your eyes are in great health. You should get an eye check every two years, just to make sure everything is all right.

When you buy products online, you must be sure you dealing with a reputable vendor with actual products, no replicas or poorly made imitations. Specifically, what vendors selling online should be offering you is every part that comes with prescription lenses like progressive, photochromic bifocal, no line bifocal, photochromic progressive, tinting, photochromic, and single vision.

Some of the others perks these eyeglasses vendors should offer are frames that are: aluminum/magnesium alloy, plastic, polyflex, acetate, nickel-free frames, bamboo, rimless frames, titanium, semi-rimless, and pure titanium frames. In addition, following the latest fashion updates and styles of the world should be a priority of these vendors, as they add new products to their line of eyeglasses.

When purchase your designer eyeglasses or designer reading glasses, you should be on the lookout for a few buyer facts:

Check for Quality & Genuineness: Make sure you are getting an authentic pair of glasses once you decide to purchase a pair. You want to be confident that you’re not paying for fake, damaged or counterfeit copies.
