On a daily basis we receive inquires asking where the sunglasses are on the AusSpecs website and we need to say that you will not find any.
So you see ... Yes you can haveyour optical glasses tinted to become Optical Sunglasses you just need to choose the colour you would like at the time of ordering .
Now we have cleared that up lets muddy the waters a little and talk about Photochromic lenses.
While clear or virtually clear indoors they become darker in the sun. The darkness of the lens is dependent on the UV radiation on any given day.
The ability to change colour is in the lens itself as opposed to a tint (an applied layer) so when ordering do not be confused between the two.
Again, dependent on your script, you will be offered a choice of a Clear to Grey transition or Clear to Brown.
You need to be aware that Photochromic lenses are not at their optimum inside a motor vehicle. The reason being that the laminated front window cuts a great deal of UV light (as do the other windows to a lesser extent) which in turn does not afford the lenses sufficient UV to react
What are Optical Sunglasses ?
Put simply these Sunglasses are your normal Optical Glasses that have had the lenses treated in some fashion to darken those lenses to protect you eyes from the bright sunshine.
Can I have my eyeglasses tinted ?
Absolutely . Tinting of reading glasses, distance glasses and Multi Focal and Bi Focal glasses are a standard option and you see them everywhere without even knowing it
Can I have Trendy Wrap Around Tinted Spectactles;
In General, No. The major obstacle in making wrap around tinted Eyeglasses is in fact the curve of the lens. Without going into great technical detail, the Lens is shaped to bend the incoming light to suit your eyes requirements [more
info]. It in not possible to accurately reproduce this in the entire wrap around lens. Some manufacturers try to overcome this problem by having a "clip-in" Lens that fits inside the wrap around glasses. These can be effective but some people still have trouble adjusting to the
two layers of lens, the inner and the outer.
Are the tints different shades of darkness.
Yes, certainly. Tints come in three (3) different grades of darkness. The lightest tine is only 15% with the next a little darker at 45%. Sunglasses tint is generally rated at 80% blockout. Quite dark and meant for outside usage.
You say tinted "Reading" Glasses. Why would I tint reading Glasses ?
The Glasses you buy from AusSpecs, although of excellent quality, are so inexpensive that many people have a pair of reading glasses specifically to sit in the sun reading their favorite book. This is much better for the health of your eyes than the reflected
sunlight from a bright white page of a book.
Should I tint my distance spectacles ?
That depends on what you want them for. Many of our AusSpecs Clients choose to have 2 pair of distance glasses. One for driving and one for watching TV etc. Again, with the cost so low this is affordable for virtually all people.
What about night driving in my Optical sunglasses?
Some people do but this is by no means recommended. Those that do generally have their glasses tinted to a 15% tint
What is Solid Tint and Graduated Tint, what is the difference ?
A solid tint is such that the lens is tinted from top to bottom with the same density of tint. Graduated Tint refers to the fact that the Density of the tint, be it 15%,45% or 80%, starts at the nominated density at the top of the lens and graduates to a very light or clear tint at the bottom
of the lens. This can have a stunning effect especially on larger frames and fashion frames. Do not confuse Graduated Lenses (tinted) with Progressive Lenses. Progressive lenses are basically Multi Focal Lenses by another name.
Are the lenses that change colour good as sunglasses ?
No matter the type of tinting each has its place but the photochromic lenses that change colour with the sun are about the most popular.
What colours can the lenses be tinted to.?
Basically every colour of the rainbow. Depending on the material your glasses are made from, the range is wide and varied. At AusSpecs we have on offer 27 different coloured lenses ranging from Dark Greens through orange, pinks and greys.
What are the lenses made of ?
Today the vast majority of lenses are made of a plastic material known as CR39 although quickly becoming very popular are the lenses made for Toughened. Although the Poly lenses can be made photochromic the option of standard tinting is not so easy. In this case the molecular
structure of the Toughened is tightly bound together thus making adhesion of a tinted layer very difficult.
What is the difference between Transitional and Photochromic ?
Realistically Nothing. The term transitional is loosely used to describe the changing of something from one state to another. In the case of sunglasses it describes the transition of the colour of the lenses from one colour or other to clear. Photochromic Lenses do exactly the same thing in
that they change from one colour to clear. Photochromic Lenses change colour proportionate to the UV rays available at the time. One brand of Photochromic lenses is the brand name " Transitions " which is the fiercely protected trade name of the Transitions Lens company
Are Photochromic Spectacle lenses expensive.
Yes they cost more than normal tinted lenses but they are not expensive when buying through AusSpecs
Do they protect me against Ultra Violet Light
The UV rating on all glasses is usually 99% or even better so realistically the Sunglasses part protects the health of your eyes against glare rather that UV. In saying that though, always check the UV Rating of the glasses you are buying and
ensure maximum protection.
Can I have Polarized Glasses as Sunglasses ?
Again, most definitely. In our Australian Coastal lifestyle Polarized lenses have become very popular and are a standard option on the AusSpecs Website.
Depending on the type of lens you choose you are offered a choice of tinting colours as you go through the system of processing your glasses.
