Types of Lenses

raybansoutlet.co.uk provides three types of lenses: Single Vision Lenses, Bifocals and Varifocals.

1. Single Vision Lenses Single vision lenses, which have the same focal power throughout the lens surface, can be further divided into distance use, computer use and reading lenses. You should choose the right lenses according to your actual vision problems.

  • Distance Use: you can choose single vision lenses for distance use if you have problems with seeing clearly from a distance, like watching movies, reading airport boards, etc.
  • Computer Use: You can choose single vision lenses for computer use if you have symptoms like headaches and double or blurred vision while working at computers (INT ADD is required on your prescription).
  • Reading: You can choose single vision lenses for reading if you have problems with seeing clearly at close-up objects, such as reading books, reports, documents, etc. (It more likely happens to people aged 40 and over)

2. Bifocals Bifocals are designed for people who have problems with seeing clearly from both close-up and distance. Suppose you are a teacher; you cannot see clearly your lecture notes and the faces of your students sitting in the back rows, in this case, you may need to think about buying yourself a pair of bifocal glasses.However you had better inquire your optician about whether you need bifocals and if you do need them, remember to provide us with NEAR ADD or INT ADD other than numbers indicating the power of lenses you need.

3. Freeform Progressives People only need progressive lenses when they need to correct visions at distance, arm-length and also close-up. However, they may cause size change of objects and even dizziness after long time of wearing. But freeform progressives with no visible lines on the surface can provide a wider vision field at all distance, avoid image jump, guarantee smooth transition. In turn, you can easily adapt to them.
