Bifocal contact lenses were developed for people with the eye condition known as presbyopia. Presbyopia typically develops after the age of 40 and involves the loss of your near vision. You will notice this condition particularly when you are reading, sewing or watching television. A bifocal lenses will have two prescriptions in one lens. People who wear bifocal contact lenses need them to see objects at a distance, as well as objects up close. While the advantage of contact lenses is that you are able to clearly see up close and far way, bifocal contact lenses have their disadvantages, too.
Vision Problems
It can be a trial and error process to find a pair of bifocal contact lenses that work for you. Since the lens alternates between distance and near, you may have difficulty adjusting to the way that the contact lens works.
Altered Depth Perception
Because of the bifocal lenses having two separate prescriptions, you may have difficulty with your depth perception. This is especially problematic when engaging in activities like driving and sports.
Not for Everyone
Not all contact lens wearers are candidates for bifocal contact lenses. The eye doctor will consider eye health and vision before determining if you can use them. People who have large pupils, a strong contact lens prescription or astigmatism may not be able to wear them.
Discomfort
You may feel eyestrain as you attempt to refocus your vision while wearing the bifocal contact lenses. Eyestrain can cause headaches. If you are susceptible to dry eye syndrome, you may want to avoid soft bifocal lenses. Soft lenses can collect protein and debris from your tears and cause a scratchy feeling on your eyes.
