If you are struggling to see things far away or up close, you may be farsighted or nearsighted. Both kinds of vision can be aided with properly prescribed lenses. However, it is possible to be both farsighted and nearsighted. To correct this kind of vision, you need bifocal lenses. At F & M Family Eyecare in Riverdale, our professional staff provides the vision testing you need to find what lenses are right for you.
Prescription of Bifocal Lenses
Types of prescriptions of bifocal lenses are:
- Monovision prescription
- Mild corrective prescription
- Concomitant use of viewing glasses
Bifocal lenses have made a remarkable improvement since the year 1990, and it has seen an improvement in optical performance, outlook, and the emergence of lenses with a high prescription rate. The past decade has seen an increase in the number of patients affected by astigmatism and presbyopia using bifocal lenses.
Four Types of Bifocal Lenses
Bifocal lenses are categorized into simultaneous and alternating vision types. In simultaneous vision type, the wearer can observe objects via distant vision by adjusting the visual axis upwards or downwards. Both the near and distant images are witnessed on the retina.
Other types of bifocal lenses include:
- Flat bifocal lenses are straight at the top to allow for the observation of close-up items.
- Round bifocal lenses, the rounded segment on the lenses allow you to see the images in half a circle.
- Executive bifocal lenses are used to correct both short-sightedness and long-sightedness in one lens.
- Segmented ribbon bifocal lenses, the ribbon-shaped lens has a rectangular area to look through. It is used when doing close-up activities such as studying.
Why Do You Need Bifocal Lenses?
The functionality of the eye decreases with age. Emphasis is made on the young wearers with distant vision problems while wearing bifocal lenses. However, it is difficult for the wearers to maintain good vision as they age because of increased chances of developing presbyopia and astigmatism.
The number of presbyopia wearers increases each passing year due to its high efficacy. Likewise, people with moderate hyperopia generally shun away from using glasses until they develop presbyopia.
