New Multifocal Contact Lenses Helping People with Presbyopia

Do you have a bad case of presbyopia? Do you also wear regular glasses and want to make the switch to contacts, but aren't sure whether they make contact lenses for this condition? Well, you'll be happy to know that a number of contact manufacturers stock a range of very comfortable presbyopia contacts, which can be worn for varying lengths of time.

What is presbyopia and how can contacts help correct the problem?

Presbyopia is a very common eye condition that usually presents itself when you reach about 40 or 50 years of age, you will know that you have it because it becomes difficult to focus on objects that are close to your face. This condition is caused by the natural affects of aging, the curvature of our lenses becomes misshapen and the muscles that control focusing loses their strength making it difficult to quickly focus in on objects at certain distances. The usual course of action is to buy a pair of prescription glasses with bifocal lenses, these come with dual lens strengths allowing you to look down at a book and read it in the correct focus.

In the past people with Presbyopia weren't able to wear contacts, but thanks to advances in medical science there are now new forms of multifocal contact lenses that correct your long and short sight. Presbyopia contacts are usually made of silicone hydrogel just like many other forms allowing higher levels of liquid retention and a good amount of oxygen to seep through to your eyes surface. The difference lies in the way that they help your eyes focus on near and far distances, here are the 3 options that are currently available for your consideration:

  1. Alternating Bifocal lenses - This type of presbyopia contact lens mimics standard bifocal lenses, the lower half of the contact lens is for viewing close objects while the central and top part is for far away objects. Alternating bifocal lenses usually come as hard gas permeable contacts, so they will stay in place when you move your eyes to alternate between focal points.

  2. Concentric ring lenses - This is a new idea that uses light intensity falling on objects to focus your vision, for example objects closer to you will have more light on them then something further away. The contacts have ring bands with different lens powers, which change as they get further away from the central point; when light reflects off an object close to you; your pupils expand to let in more light and focus on a certain ring on the contact.

  3. Aspheric multi focus lenses - This form of lens uses a similar design as the concentric ring lens, but the left and right contacts have different focal powers. The idea is that when the left and right eye work together your brain can selectively pick out the right focus for the specific objects distance. It takes about 2 weeks for your eyes to get used to, but so far this is the most popular and comfortable form of presbyopia contact lenses.
