Prescription Sunglasses Frames
why would you consider Prescription Sunglasses Frames? Well for one you want to protect your eyes from the sun and another you would still want your good old regular perfect vision when everyday tasks. You may find yourself driving or walking down the road with the sun shining in your eyes and then you want to go for some clip on lenses that you purchase or that came with your Prescription Glasses. Why go through all that hassle when you can simply get Prescription Sunglasses Frames that are a far better alternative than just regular Prescription Glasses. Contact lens users can also benefit from this as their lens will of course not keep not things such as wind, water and the sun so they may be prone to teary or watery eyes when going outside. But with Prescription Sunglasses you don't need anything extra, you just grab a pair and keep your perfect vision indoors or outdoors through a variety of conditions.
If you are concerned about style choices you do not have to worry a single bit for the number of Frames available for Prescription Sunglasses Frames are nearly just as much as those for nonprescription Frames. Even plenty of designer and celebrity type Online Eyewear Frames is a big possibility. But there is limited availability when it comes to Frames that are wrap around as extreme curves tend to distort vision making it different to see properly or at all. The materials available for Prescription Sunglasses are High Index, Polycarbonate, regular plastic and trivex, Glasses is also available but I would not recommend them as they tend to be a bit more fragile. Though they may provide the best quality, they are not recommended any longer due to them being heavier and of course as mentioned shatter easily but they are still available upon request. Another option to try out for sun wear when trying to purchase Prescription Sunglasses are lens with a photochromic tint which is also referred to as “transition lenses”, These lens automatically darken when stepping outdoors into the sunlight and then will return to a clear state once back indoors away from any sunlight.
They are quite convenient for those spending quite a bit of time outside but the required drawback is that the UV rays are required to actually hit your lens tint. Something like a car's windshield will block a part of these rays which causes the photochromic lens to not darken as well as they should. The regular lens should work well for in doors/ outdoor solutions but for even more better solution in other cases perhaps it would be best to keep a magnetic clip on with you at all times when stepping outside for the extra comfort solution especially when driving in very sunny conditions. As for nonprescription Sunglasses your only real concern should be the 100 percent protection from these UV rays and normally the color and tint density you pick really should not matter. You should be able to pick any style, color or tint long as your optician can confirm a 100 percent guarantee that they have full UV protection. In the case you want to manage for an extra bit of glare protection when light bounces off other objects and materials like water, snow etc., then for you Prescription polarized Sunglasses are also available.

This UV light is broken down in the 3 different types UVC, UVB and UVA. UVC rays tend not to reach the earth because of the earth's atmosphere which blocks them. UVB rays are the most dangerous and they make wearing Sunglasses a must but they do not go through Prescription Eyewear Frames, sun screen is also recommended during long out door sessions without proper covering. UVA has longer wave lengths and passes through Glasses easily but many tend to disagree on whether it truly causes damage to the eyes or not.

SO what exactly is blue light? The sunlight that we see contains colors such as red, orange, green, yellow and blue light rays and many other shades of these colors and depending on factors such as energy and wavelength. When they are all combined they form what we normally see sunlight or also referred to as “white light”. Without me getting in too much scientific areas and terms, they have an inverse relationship between the amounts of energy they contain and the lengths of light rays they support. Those rays that will longer wavelengths will have less energy and those that have shorter will have more energy. Those Electromagnetic rays beyond the red end of the light spectrum are called infrared but they are just warming rays and are invisible. Some lamps will also emit red light that we can actually see so we know that they are ON and working, the same can be said for other lamps and colors. The visible light are also referred to as ultra violet radiation.
UV rays since they have much higher energy can produce changes in our skin which we call a suntan. Also the tanning salons we visit when we want to get a tan also using the same principle with bulbs to produce a more controlled amount of this UV radiation. But of course there are dangers to it, if we are over exposed to these rays it can result in a particularly bad and painful suntan and even lead to skin cancer. But there are also beneficial aspects to it as taking in enough of it though out door time helps the body manufacture amounts of vitamin D to a sufficient amount.
Here are some other key points of blue light, everything you need to know is that it is literally EVERY WHERE. The sun may be our largest source of blue light when being outdoors, but there are several man made sources like TVs, Led lighting etc. Also it would be good to know that the display screens that we are attached to on a daily basis like computers, tablets, laptops, smart phone also produce a great deal of this blue light. The amount given off by these devices may be much lower then what we expect from the sun but due to the time we spend with them on a daily basis makes them dangerous. Many doctors recommend taking breaks from using these devices often in the day to exercise your body, mind and especially eyes. Your eyes are not good at blocking blue light by themselves, although they can do an adequate job of it keeping it at a distance they cannot completely block them. Sunglasses which block 100 percent of these UV rays are essential to protecting your eyes for the moment and strengthening their own response to it.
Also there is the fact that blue light can penetrate all the way to your retina which is the inner lining in the back of your eye is also very important, because lab results show that if it continues to reach that far it can leave a lasting damage which can result in macular degeneration, which of course can also lead to permanent loss of your vision. Although there are still many researches going on to determine how much of an impact these other digital screens have on our eyes and how much is truly “ too much blue light” , many eye care doctors remain concerned about the effect it may be having in increasing the risk of something like macular degeneration later in our lives. You may even say you want to block blue light all together but that also is not a good idea as it has been proven that a bit of blue light is even good for our health. It has helped improve our alertness, helps boost memory and elevates our mood conditions. Some of it is even used is something called “light Therapy” which elevates depression conditions for those from fall season through winter seasons. Some of these devices even come with filters which help with some aspects of these issues.
Here are some ways to help with eye strain from may come from these digital devices and especially computers, which should be a great help to those with prolonged daily computer use at home or at work. Several studies also show that 50 to 90 percent of those who have these daily activities may suffer from things like eye strain and other conditions that can result in some terrible things. The problems related to this can result from something like minor annoyances from eye blinking and twitching to a possible error related to work conditions and go all the way up to something like red eyes. First thing you want to do and KEEP doing is getting regular eye exams to sense and measure the amount of damage these devices may be doing to your eyes. During your visit you may want to tell your eye doctor exactly what you may be doing on a daily basis so he/she has the most information available to properly diagnose your needs. On your own you can measure how far you may sit from TV or computer screens on a daily prolonged basis so your eye doctor can test your eyes at specific working distances.
Next it would be best to use proper lightning conditions wherever and whenever you may be using these screens as eye strain can often be caused by excessively bright light coming from areas such as a window from direct or in direct sunlight, or even from interior lighting. When you use a computer your lighting should be half as bright as you would find in most offices, next be sure to take care of any exterior lighting that may find its way in. Close Drapes, blinds, shades and do whatever possible to reduce exterior light as much as possible. Also it would be a good idea to position your computer position to the side of any known windows and not in front or behind them. Many users have also reported that they feel comfortable if the lights around them not too close to where they are sitting and also not pointed directly at them as something overhead that is too bright may cause more problems than actually solve them.
Keep glare to a minimum as any reflections will also cause computer eye strain, it would be good idea to try and find an additional anti-glare screen for your computer monitor and paint your walls a darker color. If you Eyewear Glasses then be sure to purchase those with Anti-reflective or also called AR coating for additional protection as it will reduce glare by miniaturizing the amount of light that is allowed to even enter your eyes. Also it would be a good idea to upgrade the monitor or TV itself to a newer tech which in itself will help with this particular issue and go easy on your eyes. Older screen will cause much more flickering which is huge cause of eye strain and can contribute to more issues down the road. They may flicker even more greatly if your monitor refresh rate is less than 75 Hz so if you must use one of these screens at work, try to at least adjust them to something higher than that to provide some help. Some other things you can do is adjust the brightness on your screen so it stays at the approx. level of brightness/light that is around you. Just to give it a test to see if its currently Ok for you try looking at a completely white page, if it tends to make you uncomfortable after a few moments then you are using too much brightness, and if it looks too gray then you may need to raise it up instead.
Also adjust the text size and color you may be reading or writing on a daily basis as most would say that a black text on a white sheet proves to be most comfortable. You should also be blinking often when using these devices as it would help moisten your eyes preventing any possible dryness and irritation. People just tend to blink less when using computers, probably a third of normal and even then they do not fully close the eye which results in a partial blink. If the air in your office is dry that will also increase problems for your eyes and put you at a far greater risk for dry eye problems. Of course if you feel you are starting to have issues and are uncomfortable, then it would be best to make alterations as soon as possible or even go and consult with your optician.
