The Low Down on Uv Rays

Ryan Steed Said:

It is crucial to receive the right amount of light to have good vision, but too much exposure to the wrong type of light just might result in serious long-term problems. When our eyes are exposed to excessive amounts of ultraviolet light (UV) wavelengths can cause eye conditions including corneal burns (photokeratitis), growths on the conjunctiva (pterygium) and cataracts. UV rays are invisible, and that only makes them more harmful.

Ultraviolet radiation, more commonly referred to as “UV Rays,” is a part of the electromagnetic spectrum and is produced by the sun, tungsten lamps, welding arcs, and certain types of fluorescent lights. It consists of three categories: UVA, UVB, and UVC.

Fortunately, UVC (190nm to 280nm) wavelengths are absorbed by the ozone layer so for now we don’t have to worry about them. However, these high-energy radiations can cause mutations in plants and animals. UVB wavelengths (280nm to 315nm) are also higher energy and can cause sunburn, skin blistering, and skin cancer. Since none of us really enjoy any of these things we wear sun block on sunny days. (Right?) The upper portion of this spectrum (from 300nm to 315nm) is where we start to see effects on the eye. UVA (315nm to 380nm) is the section of the spectrum that hurts the most because it is totally absorbed by the eye’s crystalline lens. (Ouch!)

Our corneas transmit UV wavelengths from a range from 300nm to 400nm, so it becomes important to us and especially to our eyes to filter these wavelengths out. That is where lenses come into play. Lucky for us, the American National Standards Institute (ANSI) has mandated that lenses be made with materials that absorb or block at least 99.8% of UVB and 70% UVA.

Ultra-violet radiation may be harmful to the human eye, but with all the lens material options available today that absorb it, patients can easily get the protection they need simply by getting a good pair of glasses or sunglasses and remembering to wear them.

Things to Consider in Buying Fishing Sunglasses

Charles White Said:

d you bother to own a pair of fishing sunglasses? If you love outdoor activities like fishing, a protective eye wear is essential for you. Your eyes are one of your most delicate organs and a good pair of fishing sunglasses will ensure that they are protected from the sun’s damaging rays and foreign objects like sand and wind.

You don’t just wear any sunglasses. Wear sunglasses designed for fishing. Here are what you should consider before purchasing fishing sunglasses:

- The best fishing sunglasses are those that have polarized lenses, which block ultraviolet or UV rays so they won’t damage your eyes. UV rays damage the cornea. They cause photokeratitis, cataracts, and other eye defects. Other than protecting your eyes, fishing sunglasses allow you to see amidst the glare of the sun.

- The fishing sunglasses you choose must be hydro repellent and impact and scratch resistant. They must be sturdy, but lightweight. You wear those sunglasses for a long time while at sea. It is best that they feel like you are not wearing them. Also, sunglasses may fall from your head to the ground and break easily if they are not sturdy enough. Fishing sunglasses also come with a pouch for safekeeping or a cleaning cloth to wipe away dirt and water.

- Choose fishing sunglasses with inserts on temples and a nose piece for a comfortable fit. The inserts and nose piece also hold the sunglasses in place. The temples must be built with air channels that let the sunglasses float. This will make the sunglasses easier to find when you lose them in the water. A wrap-around shape is best to stop glare and UV rays from coming around the sides, top, and bottom.

- Choose fishing sunglasses with lens that can be interchanged to match them with the current weather. Weathers change and it would be too expensive if you buy several sunglasses with their own particular colored lens. Colors of the lens have varied purposes. You use dark lenses for a clear, bright day. You wear light-colored lenses for gloomy or cloudy weather.

- Sunglasses, especially polarized fishing sunglasses, prevent the sun’s glare from our eyes. But what if it is a cloudy day? Take note that we are exposed to the UV rays even on cloudy days, so we still need the protection. Dark cloudy days can still be glary.

- It feels good to invest on a good pair of polarized fishing sunglasses as their style can be worn everywhere and everyday. However, quality fishing sunglasses are costly. If you aren’t sure about purchasing one, try an low-priced pair first.

Where do you get the best deals in polarized fishing eye wear? There are various websites you can visit without leaving the comfort of your home. Go check websites of manufacturers of polarized fishing sunglasses. You can also visit online stores showcasing this product. You may be able to find discounts.

Sunglasses and its effects on Human Eye, Recommendations

monika Said:

UV rays

They are a part of the invisible spectrum of light with a wave length below that of visible light. These rays are invisible and has no relation with the heat of the sun, thus the winter sun has equal amount of UV rays as the summer sun. These rays are divided into UV-A, UV-B and UV-C. UV A and B are known to be the harmful ones. The sunglasses should thus protect from both these rays. There is some evidence to believe that long term UV (UV-A) exposure has a role in cataract formation which is the clouding of the lens. Also UV rays have been held responsible to cause age related macular degeneration (ARMD) which is potentially blinding retinal condition due to old age. Both these conditions can lead to reduced vision. Apart from the above conditions UV exposure can also cause a pterygium which is an over growth of the conjunctiva (skin of the eye). UV rays (UV-B) are also known to cause skin cancers which often occur on the face near the eyes. All of these conditions can be delayed or even prevented by good UV protection of the eyes.

Options in sunglasses

UV protection: Glasses need to have a special coating on it to be able to block the UV rays from passing through. Glasses may have different levels of UV protection, the recommended level is the maximum i.e. 99 to 100% of UV protection of both UV-A and UV-B rays. Polarized glasses: These glasses have special lenses that reduce glare. They are usually expensive and would help reduce glare directly from the sun or reflected from the road, sand, water or snow. This is independent of UV protection. Photochromatic glasses: These lenses have the property of changing the darkness of tint depending on the amount of light exposure. They are dark in the sun and automatically become light coloured once taken indoors. This again is independent of UV protection. Gradient glasses: These glasses are dark in the upper part and become lighter in the lower half of the lens. This is useful while driving to see the dash board through the lighter part. Tints: There are a number of coloured tints available eg black, brown, grey, blue. This is a personal choice.

Myths

There are a lot of misconceptions regarding sunglasses. Doctors at Hinduja Hospital try to clarify a few.The common myths while getting a pair of sunglasses is that a darker or more expensive pair of glasses will give good protection. Darkness has nothing to do with UV protection, in fact it is more harmful to wear dark sunglasses without UV protection than not to wear sunglasses at all. This is because behind dark glasses the size of the pupil becomes larger and without UV coating allowing more harmful UV rays to enter the eye which would have otherwise been partially blocked due to a smaller pupil without any glasses. Also most people believe that sunglasses are meant only for the summer months, which is untrue since the UV rays are almost equally harmful all the year round.

Recommendations

You will find many brands & lots of stuff as in sunglasses, but the most recommended by doctors are the following.

Sunglasses should have a 99 to 100% protection from UV rays (both UV-A and UV-B). Most branded sunglasses will have this information with the product. Some brands have UV 400 written in them which means, it blocks up to 400 nm of light which includes the UV rays. In case one needs to get prescription sunglasses from the opticians then the amount of UV protection on any lens can be measured by a machine that most good opticians possess. Since UV damage is long term, starting early is recommended. Children should wear sunglasses whilst outdoors in direct sunlight whenever possible. Very few brands make sunglasses for children and since it is usually difficult to get young children to keep glasses on, a rimmed hat or a cap can usually provide substantial protection.

It is recommended to choose sunglasses that match your face shape, features and your personal style. Although purchasing sunglasses is more of a challenge than you imagined, perhaps this article will help you transform this activity into a pleasant one.

Sunglasses are available in a wide range nowadays and most people find it hard to choose the one pair that suits them best. The first step to purchasing sunglasses is figuring out if your face is round, oval, square or heart-shaped. Look in the mirror and see which of these forms your face has. People with round faces should avoid round frames and buy something in an angular shape.

A Quick Guide to Sunglass Wear-Why, When and Where

Michael Burkhart Said:

Sunglasses have been considered a fashion statement for decades, worn by celebrities and other famous folks in either a desperate attempt to conceal their identity or to play the movie star role, all while looking fabulous. Even though this usage still exists, more and more average people are realizing the importance of wearing them to protect their invaluable eyesight.

Even though the sun is over 93 million miles away, its harmful rays can be the sole cause of an assortment of health problems. Ultra violet radiation (also known as UV radiation or UV rays) is probably the largest solar-based contributor to such health problems. UV-A, UV-B and UV-C are the categories of UV radiation known to us at this time. With the exception of UV-C (which is believed to be absorbed by the ozone layer around the earth), these rays can have both short and long term effects to your eyes and your vision.

Now that you’re a bit more aware of why, you need to know more about when. For instance, UV rays reflect off of snow, sand, pavement and water, causing a greater risk for damage than in a “greener” environment, like a park or field. The rays in a reflective situation will be coming at you from two angles instead of the one in a greener environment, as the rays will bounce off of the reflective surface in addition to coming at you straight on. Wearing sunglasses that offer you UV protection will help to protect your eyes when in this type of circumstance.

High altitude is another situation for which sunglasses should be worn. UV rays are filtered out through the earth’s atmosphere, resulting in lesser amounts of the harmful rays converging with the earth’s surface. Simply put, high altitudes yield a greater amount of the rays because they haven’t had the chance to be filtered yet.

Between the hours of 10 am and 4 pm is the time of day when the UV rays are their most powerful, so protective eyewear is crucial during this timeframe, whether or not the sun is bright and beaming in the sky or hidden behind large amounts of clouds (both white and fluffy and dark and gloomy). UV rays can easily leak through the cloud cover and rain to wreak its irreversible damage on your eyes.

Since you now are aware of the situations that necessitate proper eyewear protection, you need a brief list of what to look for when shopping for your ideal pair of sunglasses. Typically, lenses that are green, brown or grey work the best, combined with a feature that filters out of at least 99% of UV-A and UV-B radiation and 75% – 90% of visible light. Taking care of your baby blues, browns and greens now will ensure you a lifetime of beautiful visions.
