If you are looking for a new pair of glasses to protect your eyes from the suns rays, you may like to consider purchasing a decent pair of polarised sunglasses. There is no need to spend a lot of money, although a great deal of the designer sunglasses will protect you and may not be as expensive as you think.
Originally developed by Edwin Land in 1936, lenses are now either coated with a protective substance or have a filter enclosed within them. Polarisation now absorbs solar glare from reflective surfaces by up to 99% and counteracts the bright glare to the eye by restricting the light waves to a singular direction.
Its not just in the summer you need worry about the sun but in the winter as well especially if you are involved in winter sports. For example, if you are skiing or snowboarding you need to make sure your ski goggles protect you adequately as the sun will bounce off the snow. However, if there is a danger of thin ice polarised sunglasses could cause problems because in some cases, definition will be lost because of the lack of reflection off the landscape. If there is no snow but bright conditions youll also get this bounce effect from wet surfaces. An example of someone who would benefit from polarised sunglasses are fisherman, as these would make it easier for them to see more clearly into the water without the sun blinding their vision. Therefore it is important to remember that safety rather than fashion should be your foremost consideration.
Considering there are many fakes around, test whether your polarised sunglasses are authentic by rotating them and watching to see if the light passing through the lens changes intensity – it should not. Don’t go for cheap imitations, it is your sight we are talking about.
Your sunglasses should also protect against 100% of all UV rays ( UVA, UVB and UVC). You should also remember that despite the colour or darkness of the lens, it is the clear outer coating that filters the rays and not the colour.
UV radiation comes in at least two primary forms, UVA and UVB and both carry their own dangers. UVA can lead to premature skin aging while UVB may cause skin cancer. UVC is a third type of radiation and is mostly found in artificial sources such as certain types of lamps. While short-term exposure is not really harmful to the eyes, repeated and extended exposure is. What you need to look for is a 99 – 100% protection against UV, irrespective of the price of your glasses or the darkness of the lens.
They may cost you a little more but even if they are a second pair, there are certainly many benefits to having polarised sunglasses.

The most popular types of designer sunglasses include aviators and anything Oakley! Oakley sunglasses are probably the most popular brand and certainly have a very extensive range, including aviators. However, aviator sunglasses are typically associated with Rayban who originally developed them way back for the military. Electric sunglasses are also very popular and have some great styles.
Some designer sunglasses are possibly more associated with women’s sunglasses. These would include Dolce and Gabbana and Armani of course.
Because of the cost of some of the designer sun glasses, if the label is really important to you, the last thing you want is to end up with a fakes! There are tips on this site to help you avoid this but a rule-of-thumb is usually to pick them up and hold them. The fakes will feel cheaper and generally, it will be obvious that they are not of the same quality.
It is important to note here that you don’t have to have designer label sunglasses to get good glasses. There are plenty of lesser known brands that provide good value for money. Also, if you find a frame you like, you can often have prescription lenses inserted by your optician.
It is also particularly important to be careful of really cheap polarised sunglasses. If you need this type of lens, check you actually have them! Again, you will find tips on how to do this on this site.
All-in-all, there are many options available to you when looking for your new sunglasses. Get a cheap throwaway pair because fashions will change next year anyway, get designer label sunglasses as this is important to you or have prescription sunglasses made.
To answer this question simply – it depends on what you paid for them. If they were cheapies they will more than likely have plastic lenses and you should just get another pair, even if they are polarised as the polarisation will be compromised.
However, if you have a more expensive pair, such as a pair from the Oakley sunglass range, instead of getting scratches out of sunglasses you can order a new set of lenses from your supplier or from Oakley direct.
There are some who suggest that you can mend high quality lenses but if they are still under warranty, once you try this you will void the warranty. If they are out of warranty, there the suggestions mentioned is to make light circular movements using a soft cloth and white non-abrasive toothpaste. Personally, I’d just replace them as I don’t think toothpaste can get scratches out of coloured lenses without it showing!
You brought your sunglasses in the first place to protect your eyes and look good – so unless anything has changed either change your glasses or get new lenses. To try and get scratches out of sunglasses is IMHO a waste of time.
