Nowadays, the bifocal or progressive prescription sunglasses are much popular and welcomed by hyperopia sufferers. But, by using bifocal or progressive glasses, one should pay special attention to the adjustment period. Here I’d like to show you some common senses in using this kind of glasses. If you begin to wear bifocal or progressive eyewear, you need to learn how to see things in varied distances.

• Lift up head and look at the eye level through the upper part of the lenses to see distant objects clearly.
• Objects at close range: there should be an angle of about 45
• Look through the middle part of the lenses to see the things in medium distance
• The transition from top to bottom corresponds each distance from far to near.

When you wear bifocal or progressive eyeglasses for the first time, it is likely you will feel uncomfortable accompanied with these symptoms.

• You will feel a little faint, hard to keep balance when walking, You should be careful on the stairs.
• The space sense changes There may be some mistakes between the actual distance and that you judged.
• You may feel uncomfortable in eyes when you force your eyeballs deliberately to downside to see nearby objects.
• Things will be blurring when seen through the blurred vision area around the lens.

Thus, you can move your head to adjust the vision area and see things clearly, but not move your eyeballs. Look at objects from distant zone, near distance zone or middle distance zone as much as possible.
