The invention of contact lenses made life easier for the spectacle wearers. Spectacles are heavier, may not be convenient for everyone, and affect the appearance. While contact lenses fit close to the eyes, are completely unnoticeable, and are more convenient. They, in fact, correct the vision more rightly than the spectacles in some cases.
While it may be illegal to buy contact lenses without a prescription, contactlenses4.us offers a wide range of lenses from major brands and delivers the product right at your doorstep without asking for the prescription. However, you have to get the glasses made, choose the right frame that suits your face, and get your eyes checked, and then place the order. This further becomes a reason why contact lenses make for a better option.
What are Future Contact Lenses?
Future lenses or smart lenses use the technology to provide you the benefits that are more than just seeing clearly. The future lenses may monitor your glucose levels in the blood, may let you take pictures with your eyes. It might sound like fictional but these technologies are already being worked upon.
Companies like Sony, Samsung, Columbia University Medical Centre are developing exciting and new technology to improve your vision. Lenses that let you take pictures and project pictures in front of the wearer, monitor glucose levels, deliver medicine in your eyes and transition lenses are being made.
Transition Contact Lenses
A person may face dramatic difference in their vision due to bright light. People with light sensitivity specifically struggle with very bright lights that may cause pain. In such cases, transition lenses would help, as they can adjust to changing light in the surroundings, helping them see clearly as they move from bright light to dark.
These smart lenses block blue light and harmful UV rays that come from your laptop, tablet, and mobile phone screens. If you face too much exposure to the blue light, your retina may be damaged causing blindness. However, with transition lenses would help you preserve your eyes’ health. It is essential to note that these lenses are not the alternative to sunglasses. Transition lenses and sunglasses must be worn at same time to make your that your eyes are completely protected from the UV light.
Drug-Delivery Contac Lenses
For some people, eye drops are difficult to use, may cause side effects or irritation. Usually, only a tiny amount of eye drops are absorbed by the eye, at times as little as 5%. Some people feel difficulty and pain that discourages them from using eye drops as per the prescription. However, the drug-delivery future lenses could solve this issue.
These lenses can deliver the medicine to the eyes gradually over time. Along with improved application as compared to the eye drops, this technique improves the amount and speed of the medicine that is distributed in the eye with very less to no side effects. People with glaucoma, dry eye conditions, and who recently underwent eye surgery would be able to benefit a lot from these lenses.
Auto-Focusing Contact Lenses
Would not it be exceptional if your eyes could auto-focus within a millisecond? There is research going on for such to make this possibility real. People with long-sightedness or presbyopia would benefit a lot from this technology. These lenses were inspired by elephant nose fish and the unusual eye shape it has, which enables them to see clearly in muddy and dark water.
Telescopic Contact Lenses
Have you ever wished to move between magnified and normal vision? Scientists have made such lenses that allow you to zoom the vision out and in like a telescope. The lenses have fixed mirrors in central part of the contact lens and with the utilization of 3D glasses, you can zoom out and in your surroundings with ease.
For people with AMD or age-related Macular degeneration, these lenses would be extremely useful. Those with this condition can see via their eyes’ perimeter clearly but center of such people’s vision is missing or blurry. These lenses are already been made into prototype and tested on human-sized eye model, but more refinements need to be made still.
Thermal Vision Lenses
As per the developers at University of Michigan, it may be possible to apply thermal vision technology into the contact lenses. This would let soldiers see better at night enabling them to sense animals, humans, and devices through heat they produce. Yes, we currently have infrared detectors for this, but this technology would eliminate the need for carrying the bulky and large cooling equipment.
Contact Lenses That Treat Nearsightedness Or Myopia
Nearsightedness or Myopia is reaching epidemic proportions. More than 90% of university students in China are affected by Myopia. This could be because of reduced time spent outdoors and excessive screen time. Slowing the progression of nearsightedness improves vision. This decreases the risk of eye diseases that are more advanced like glaucoma.
Monthly overnight wear contact lenses or daily disposables can correct the vision. But treating myopia would involve wearing ortho-k or orthokeratology overnight. These lenses reform the eye curvature and can provide great results.
However, these results are temporary, meaning they wear off once you stop wearing these lenses. But the researchers are working on soft contact lenses, which can treat myopia permanently. These contact lenses have superior design that decreases myopia’s axial progression.
What Could Be the Future?
We could be experiencing the augmented reality in the future through the contact lenses. This would let us display pictures, play the videos, and open website browsers right in the line of our vision. We could be capturing images simply by blinking soon.
Additionally, we could see objects come into focus hat are once blurry in foreground, conjure city maps right in front of our eyes as we walk, and a lot more. Gone are the days when a pair of contact lenses was only utilized for vision correction. With so many technological advancements, anticipating what the future brings us in terms of additions to contact lenses is not highly predictable.
