Since your eyes are some of the most sensitive organs in your body, you need to ensure that your contacts are always up to date. Here are three examples of the latest developments concerning contact lenses and how they can help you:
Use of Silicone Hydrogel Material
One of the disadvantages of wearing contact lenses for long periods is that they reduce the amount of oxygen reaching your eye. This leads to hypoxia, a condition in which your eye tissues experience oxygen deprivation and cannot function efficiently.
Contact lenses made from silicone hydrogel, a flexible plastic-like material, reduce this problem. This is because the material allows more oxygen to reach your eyes than many other materials used in contacts, such as regular hydrogel. Talk with a professional, like Modern Eyez, if you are considering switching to a different contact brand.
Lenses That Measure Intraocular Pressure
Glaucoma is an eye condition associated with the buildup of pressure inside the eye, and those that wear contacts and have poor eyesight are at risk. This pressure is called intraocular pressure, and too much of it can damage the optic nerve, which transfers image signals to the brain. Untreated glaucoma can cause permanent eye damage.
Researchers have now come up with contact lenses that can measure and record the changes in intraocular pressure. These are disposable lenses that you only wear for 24 hours. The recorded data allows your eye doctor to measure the pressure fluctuations and come up with better medication schedules.
Lenses that Protect You from UV Radiation
Ultraviolet (UV) radiation is not good for your eyes. UV rays have been linked to numerous vision problems, including cataracts, temporary vision loss, and macular degeneration. One of the ways of protecting your eyes from these harmful rays is to wear wraparound sunglasses whenever you are out in the sun. However, there may be times when you can't wear your sunglasses, and this is where contact lenses come in.
There are now contact lenses equipped with UV blockers that reduce the amount of UV radiation reaching your eyes. The lenses do this by absorbing some of the radiation. This beneficial effect is even greater if you wear these contact lenses regularly.
It's difficult to keep abreast of all this information if you don't work in the optometric industry. Your eye doctor or optometrist, however, has information on the latest design of contact lenses. This is one of the reasons why you should not start wearing new contact lenses without consulting your doctor first.
