A Buyer's Guide to Designer Sunglasses
With all the knowledge that we have today about the health of our eyes, we all know that we need to protect them from harmful UV rays produced by the Sun. That means wearing sunglasses. Preferably a pair that enhances your good looks.
In addition to looking good, there are several other factors to consider in deciding what pair of sunglasses to buy:
• Amount of light that is blocked, affecting your ability to see well.
• Materials used in construction, affecting durability as well as style.
• Fit, affecting comfort and your ability to wear them for long periods.
• Lens options.
This indicates how dark the lenses are, and is typically expressed as a percentage. For example, 70% means that the lenses block out 70% of the light, and would therefore be a darker lens.
Remember that blocking light improves your vision up to a point, but too much light blockage will make it difficult to pick out details, notice items in shadows, and just make it more difficult to see overall. Consider when you’ll be wearing them, and what you’ll be using them for.
If you’ll be using them while driving, consider the time of day that you drive most often and how a darker or lighter lens will affect your ability to drive safely. If you’ll simply be hanging out on the beach, then you’ll probably be more concerned with how good a darker or lighter lens makes you look.
Materials vary from plastic to titanium. Light weight metals like titanium increase durability while retaining comfort. Plastic on the other hand is much cheaper. A good compromise between cheap plastic and very expensive titanium is nylon. The flexibility of nylon improves its durability over plastic while costing much less than titanium.
The material will also affect the style of the frame, something to consider when choosing between plastic, nylon, or metal.
You may find the perfect fashionable designer sunglasses, but until you try them on, you won’t know how well they fit.
A bad fit can affect long term comfort, or result in sunglasses that don’t stay on very well. When first trying on a pair of designer sunglasses, make note of the pressure points and overall feel. While they may feel okay when you first put them on, sunglasses that apply pressure in the wrong places can lead to headaches after being worn for several hours.
Most designer sunglasses can be adjusted for proper fit.
Designer sunglasses will usually have optically correct lenses. Cheaper sunglasses can often have imperfections in the lenses that distort your view. When it comes to buy sunglasses, sticking with the designer names will generally ensure that you don’t run into this problem. And even if you do, the manufacturers of the well known designer sunglasses want to protect their good name, and will usually gladly replace bad lenses.
Lenses also come in different materials:
Glass – though scratch resistant with the best viewing quality, glass is heavier, costs more, and is more fragile than other materials.
CR39 Plastic – weighs half as much as glass and has a high level of impact resistance.
Polycarbonate Plastic – very strong, and is often used for safety glasses. They also offer built-in UV protection.
Acrylic Plastic – the lightest and cheapest. Acrylic lenses will scratch very easily, and must be specially treated to include UV protection.
Buying designer sunglasses is more than just about the fashion. Be sure to protect your eyes with a quality lens and a comfortable frame. With all the knowledge that we have today about the health of our eyes, we all know that we need to protect them from harmful UV rays produced by the Sun. That means wearing sunglasses. Preferably a pair that enhances your good looks.
