This is the single most important factor while you buy sunglasses. Always get ones that offer great ultraviolet protection as that is the basic purpose of these glasses. Not having the best looking shades will not be damaging your eyes but not having UV protection certainly will. Have the best protection so that you eyes are not affected by the scorching sun.
Determine what kind of activity you will need the sunglasses for? It can be driving, walking, hunting or for some other reasons. These are important factors that will dictate that what kind of tint will suit your needs. A sports person will certainly need something different from say someone who is wearing them for a driving trip.
Understand Various Options
Each kind of tint has its own benefits. Understand these properly and compare the various options that you have available. This is an important part of selecting your tint as you should be able to identify our particular need or needs. Select a tint that serves your purpose the most.
For the purpose of using shades for styling purpose, you should go for coloured tinting. You can get from blue to red to orange and can wear them with different coloured clothing. These ones, however, are not advisable for driving.
For sports use, you can utilise darker, polarised sunglasses that offer a lot of reflection. These can be particularly useful in skiing where protection from the sun is very important. For daily wear, lighter colours should do the job quite well.
