Faddy bifocal sunglasses for smart girl
At present, bifocals are the favorite of the increasing hyperopia sufferers. While, unlike the common eyeglasses, there is a process for adjustment in use of bifocal or progressive glasses. Following are some basic knowledge in adapting this type of eyeglasses.
If you begin to wear bifocal or progressive glasses, you need to learn how to see things in varied distances.
- In order to distinguish distance objects, please raise your head and look through the upper lenses.
- Keep your head with a depression angle of 45 degrees, and look down through the lower lenses to see nearby objects clearly.
- You need to look through the middle area of the lenses to see objects at medium range
- The nearer the objects locate, the lower of the lenses your eyes should focus on and vice versa.
When you wear progressive glasses for the first time, it is likely you will feel uncomfortable accompanied with these symptoms.
- It makes one dizzy, be rocky while walking,have to be beware of the vision when exercising or walking upstairs.
- You are probably to find that there are variations on the space state.
- You are unable to distinguish the objects on different distances.
- When you look at the near things, you may find a little discomfort on eyes in that you have to move down your eyeballs.
- The edge of the lenses is the image distortion area, you can’t view things clearly through this part.
So, it is best for people who wear bifocal or progressive glasses for the first time to move head instead of eyeballs when look at things.You’ better do as progressive eyeglasses works: different parts of lenses work for objects in varied distances.
