Top 5 Tips to Buying Cheap Glasses and Sunglasses

There are lots of choices when it comes to cheap glasses and sunglasses. It is hard to choose from all the available models on the market today. Cheap glasses and sunglasses are more than just fashion accessories. They also protect the eyes from the rays of the sun. Here are the tips to help you make the right choice. 

If you have an oval face, you can wear any type of cheap glasses and sunglasses as any shape complements well with the facial features. People with a heart-shaped face should avoid wearing cat-eye and aviators because they highlight the narrow jaw line. People with square face should wear classic oval and cat-eye frames that are suitable for squared chins, strong jaw, and broad forehead. People with round heads must choose frames with more rectangular and wider frames that help offset the size of their head. 

When you find designer glasses at affordable prices, you must still consider how much UV rays they can block. Prolonged exposure to sunlight can result to several eye diseases such as cataracts. You should opt for glasses with 400nm UV absorption that provides 100 percent UV protection. 

When you find cheap glasses, ensure that they meet these standards so that your eyesight is protected from UV rays. Most people choose sunglasses based on their frames without knowing whether the lenses can actually protect their eyes. 

Another thing you must check when buying sunglasses is the optical quality of the lenses. Good lenses will not distort the images in front of them. Straight lines remain straight. Poor quality lenses will make lines wiggly. Designer glasses at affordable prices are the safe choices because they ensure that they only use high quality materials. 

If you are going to wear your sunglasses while playing sports, make sure the lenses are made of polycarbonate plastic. They are 20 times more impact resistant than the normal glass lenses. They must also have a scratch-resistant finish because the polycarbonate scratches easily than normal glass lenses.  

The last thing you need to consider is the colour of the lenses. There are several colours to choose from aside from the typical black. Green lenses are good for cyclists, runners and golfers because they allow the user to see true colours. Brown lenses brighten the vision and good for high-glare sports such as boating, skiing and fishing. Grey lenses are darker and good for everyday wear, especially when the sun is bright. 

These are the tips you need to keep in mind when buying cheap glasses and sunglasses. Even though they are cheap, make sure that they can protect your eyes from the harmful UV rays.
