Scratched lenses are probably one of the most common causes of problems of owners for expensive designer sunglasses.
Even the smallest blemish can spoil both the look of the frames and ruin the experience of wearing sunglasses.
And there are two common mistakes that owners make when faced with a scratched or blemished sunglasses lens on their favourite shades.
One is to throw the spectacles in the bin, even expensive designer frames, and buy a new pair; the other is to try and repair the lens themselves.
A quick search on the internet will throw up plenty of sites that offer advice and self-help remedies for repairing scratched lenses.
The long experience of expert technicians at AlphaOmega is that trying to rid your lens of a scratch will only worsen matters.
By all means, try if you must (and we offer some essential tips on this later on), but our advice is to let AlphaOmega experts take a look first.
Sunglasses lenses are typically manufactured from glass or a plastic acetate compound. If the lens is made of glass, then the scratch is almost impossible to remove.
Glass is much more resistant to scratches in the first place, so if it does get marked, the scratch will almost certainly be too deep for any decent repair.
And any attempt to remove it will require grinding away at the glass itself, resulting in a thinner lens and a distorted image.
The only hope here is if your sunglasses lens has been given a scratch-resistant coating, and it is this that has suffered the damage.
Rubbing the lens gently with a microfibre cloth soaked in lens cleaning solution may do the trick but don't hold your breath.
Lenses made of plastic compounds are much more prone to scratching, although modern blends have made them much more resistant to damage than they once were.
If the lenses are polarised, you will need a specialist extra-fine abrasive solution to do the job, although the chances of ruining the polarising properties are high.
Amateur remedies for cleaning shallow scratches on non-polarised lenses include using a lens cleaning kit, furniture polish, brass polish, toothpaste, baking powder petroleum jelly and car wax.
Your chances of repairing anything other than hairline scratches with amateur cleaning are small. The chances of ruining the lenses are high, especially for those with a special coating.
At best, you will probably get sunglasses with lenses of two 'shades', a different one for each eye.
In all but the rarest instances, the solution at AlphaOmega is to replace the lenses completely. An AlphaOmgega repair may not be as expensive as you might think.
