ALL ABOUT PRESCRIPTION SUNGLASSES (GUEST POST)

Sunglasses are made of either non-prescription or prescription lenses that are made darkened to give an ample amount of protection for our eyes against very bright light or even possibly ultraviolet lights. They provide shade to the eyes and protect them from other things such as dust, dirt, or particles in the wind. Glasses Mississauga are mainly made from prescription lenses. 

The importance of prescription glasses 

Glasses Mississauga are very versatile. They can be used for a number of various outdoor and sports related activities which can range from cycling right to mountain climbing. Often, in outdoors, one can expect plenty of flying debris, high winds, damaging bright visible light and even ultraviolet lights. Prescription sunglasses can protect its wearer from all these things without hindering their vision or comfort of the wearer. 

For many years, glasses Mississauga have been made and reinvented to give top- quality vision to its wearer, even in the most extreme conditions. The frames of these glasses are durable, lightweight and flexible, with an anti- slip component which is crucial to the outdoor market. The lenses are coated with special films which provide cover and protection against UV ray, which are very harmful to the eyes. 

What to look for 

When purchasing new sunglasses, there are many elements that need to be factorised in order to choose the correct pair of glasses. One factor to consider is the type of outdoor activity the individual takes part in. The types of lens, frames etc. all differ in terms of the type of activity. 

Lenses are a key factor as they differ from activity to activity. Some lenses are required to be a different colour altogether, for the purpose of giving the wearer a better depth of focus while engaging in the activity. 

Lenses can be scratch resistant, dust resistant, water resistant, to protect the wearer from the elements. They can also be shatterproof, lightweight, and impact resistant for a heavier outdoors lifestyle. Special coatings protect these lenses form the elements as well, along with giving the glasses more structural durability. 

Colour options for the lenses also help a great deal for the wearer. It affects the amount of visible light that can reach the wearer’s eyes and better defines objects. Red, blue, green, yellow, grey etc. and many more are given as an option for the wearer. 

Interchangeable lens frames are also an option for wearers who wish to have one pair of glasses for everything. This gives the wearer the option of removing and switching glasses according to his preference or to adapt to his surrounding environment. Frames are another important factor which adds on to the wearer’s comfort. They can either be worn like normal glasses or have the option of wrap- around frames which give the wearer more ease and freedom in movement. 

It is advised to take a good look at the available options before buying the sunglasses of your choice. There are many certified glasses Mississauga companies that cater to these specifications.

ALTHOUGH IT’S HOT, IT WILL GET HOTTER! BE READY!

We hope your Fourth of July celebration went off without a hitch!  No traffic tickets, no sunburn, no fireworks injuries, and or other obstacles in the way of slowing you down to get back to work today, hopefully.  This time of the year is the greatest time for us to enjoy our freedom and show our support for our troops.  As you go through the rest of the summer, keep them in mind and let’s hope they are all back to help us celebrate in the near future.  One thing to remember: it’s even hotter where they are than where we are! 

July is UV Safety Month, sponsored by the American Academy of Ophthalmology.  Ultraviolet (UV) radiation is the main cause of skin cancer, and can also damage your eyes.  This is a good time to send the message of safety during sun and fun times.  Those who work in the sun also need to be warned about the damage that UV rays can cause, in order to take precautions to avoid these types of health problems. 

The highest risk for getting skin cancer seems to be for those who have:

  • Blond or red hair;
  • Blue or green eyes;
  • White or light-colored skin with freckles.

Those people especially, but let’s include everyone else to take these steps to prevent skin cancer:

  • Stay out of the sun between 10 a.m. and 4 p.m. if possible;
  • Use sunscreen with SPF 30 or higher.
  • Use sunscreen that has UVA and UVB protection – “broad spectrum” sunscreen.
  • Cover up with long sleeves and a hat;
  • Check your skin regularly for any changes. 

UV damage can also cause wrinkles and blotchy skin.  Skin cancer is the most common type of cancer in the United States.  Tanning indoors is not safe, either.  According to Dr. Carol Cola, who works in the Department of Surgery at Pottstown Memorial Medical Center, around 90 per cent of skin cancers appear on the neck, head, ears, lips, or hands – areas that are most often exposed to the sun.  Sunburn can happen anywhere – driving a car, through a glass window, or reflections off concrete, sand, or snow. 

To do a self-examination for skin cancer, simply watch for any changes in size or color of freckles, moles, or birthmarks.  If you notice anything different, see your physician or dermatologist.  Recent studies by the Skin Cancer Foundation state that studies have recently indicated that only 23 per cent of damage from UV exposure happens to most young people by the age of 18 – not the 80 per cent that was formerly thought to be.  This shows that there is benefit to be gained for persons of any age, to protect themselves from damaging rays.  It still is important that we use sunscreen on our children and sunshades that will protect their eyes. 

UVA and UVB rays can hurt your eyes.  This type of radiation can lead to cataracts, macular degeneration and some cancers.  The use of proper types of sunshades can help prevent this from happening.  It’s always been “cool” to wear sunshades, just be sure you purchase polarized ones that protect from both UVA and UVB rays. 

Everyone at work in should get involved in spreading the message that damage from the sun can be very harmful, even deadly!  Posters need to be placed right by the doors before workers step out into that hot sun.  Companies could ask a health professional to demonstrate how to check skin regularly for skin-cancer warning signs.  A local dermatologist, registered nurse, or public health official would be happy to help educate your employees about the dangers of skin cancer.  Place a memo in their paychecks to remind them to do all they can to protect their skin and eyes from radiation from the sun.  

We hope this will serve as a reminder to all of you to try to stay as cool as possible this summer – it is already a scorcher!   There are many products that can help protect you, so take advantage of them.

IDEAS ABOUT UV PROTECTION

We haven’t forgotten that July is UV Protection Month, a reminder to all of us to protect our eyes and skin!  It is most important that we do everything we can to preserve our vision.  It is unimaginable to think about being without the gift of sight, or facing malenoma, a life-threatening form of skin cancer.

You have heard  about the types of UV rays, but let’s review them again:

UV-C rays are the most harmful, but are blocked by the ozone layer.  If they ever reach the earth’s surface, they could cause serious health concerns.  UV-B rays have high doses which cause sunburn and can cause skin cancer.  Other age-related signs of too much sun are wrinkles and skin discoloration.  UV-A rays can pass through the cornea, reaching the lens and retina inside the eye.  Overexposure of these rays is linked to certain types of cataracts, and development of macular degeneration.  Both these types of rays are shielded by the ozone layer, therefore, they are not as harmful as UV-C.  Because of weather changes, and seasons, however, we must be mindful that there may be some depletion of the ozone layer.

It is very important to remind you to select sunglasses that block 99-100% of both UV-A and UV-B radiation.  Also be sure that the lens are free from distortion and any imperfections.  Wrap-around styles allow more protection to the sides of the face.  It is of the utmost importance to protect children’s eyes from these rays, as well.  They need to wear glasses that contain the same element of protection as an adult’s,  not toy ones.  Much of the damage from the sun happens during childhood, only to show up later in life.  It goes without saying that in addition to sunglasses, suncreen with a sun protection factor (SPF) of at least 15 should be used often while anyone is in the sun, as well as wearing a wide-brimmed hat, or using an umbrella, if sitting outdoors.

Those who work outside should take precautions to wear eye protection and other types of personal protective equipment.  There are special sunshields that fit hardhats that help protect the face from the sun.

The following UV Index helps explain the stages of exposure to rays:

  • 2 or Less =   Low, for average person.  On hot days, persons should still wear glasses and sunscreen.
  • 3 to 5 =           Moderate.  Use the shadow test.  In early morning or late afternoon if you are taller than your shadow, UV exposure is likely to be low.  If your shadow is shorter around mid-day, levels of UV are higher.
  • 6-7=                  High.  From 10 a.m. to 4 p.m. is the worst time to be outdoors.  Be sure to use at least 15 SPF sunscreen, and often.
  • 8-10=                Very high.  Because your skin will burn quickly, take extra precautions.
  • 11+ =                  Extreme.  Stay out of the sun, especially from 10 a.m. to 4 p.m. if possible.

Another thing to remember, if you are around sand or water, is that reflections can damage your eyes.  Reflections from snow almost double that from sand.  Persons with darker skin and eyes  need to protect their eyes the same as more fair persons.

There’s no way we can be immune from the dangers of overexposure from UV rays.  But we can take all the precautions possible to avoid damage to our eyes and skin.
