Contact Lenses 101

Tuesday, April 8, 2014
Good evening! It's been a while :)

Today, I'll be sharing to you on 101 of 
Contact Lenses, which I had mention before that I learn some of it from my optician.
**Disclaimer: Mostly of the picture were adapted from Google search.

Everyone should have know that WHAT is contact lens. Contact lens is a thin plastic lens placed directly on the surface of the eye to correct visual defects.

Moving with the time, nowadays there's also colored contact lens for cosmetic purpose. Colored contact lenses are also available without power for persons who have perfect (or almost perfect) eyesight. They're very popular to the asians. Unlike the westerners, asians naturally have black iris. Thus, colored contact lenses would be a big help for them to enhance their eyes with some colors.

How were those contact lenses made?
A sandwich technology would be implied on the manufacturing of colored contact lenses 

This is rather a basic lens sandwiching. There's some of the lenses are having more than one color and it'll look like the picture below, which is a sandwiching layers for 3-toned lenses.

Contact lenses seems attractive right? However, I believe all of you would have heard or seen some cases about consumers getting eye infections after wearing contact lenses. 

Why would these happen? Here's some main reason that would likely have causes it.

1.Contact Lenses were bought from random places or online. 

You all could see there's various of lenses selling at some random stall at the night market or maybe on the internet. Futhermore, the price is as cheap as RM10. How is that possible that the lenses are selling at such inexpensive price? Well, it should be know that you get what you have actually paid for. Those lenses are actually basically 'black-hearted' goods , which means sinister cargo, made and distributed from china even it's stated that those lenses were made in Korea.

As a matter of fact, those defected products were repackaged by the manufacturers and being sold to consumers. The reason why those lenses could  found at random stalls instead of optical shops is because that they're not qualified by the respective administration in the the particular country. Also, each optical shop would have their store code and every distributor of approved lenses would check out what the store is actually selling as well as the respective code.The distributor will not sell, distribute unless  they have the permission or are required by law to do so.  There may be a lot of catchy designs and patterns,  but it's not safe and not very hygienic. However, there's still a lot of girls chose beauty instead of their eyes. 

However, there's still some that bought from optical shops also tends to get into problem after wearing contact lenses. Why?

2. Overwearing
When we're wearing our lenses, proteins may build up on the surface of the lens. The protein that builds up is not the protein that we consume everyday and instead it's build up when our eye self-clean through tear production. Our eyes are naturally designed undergo this self-clean everyday. rotein and other oils that are found in your tears have a tendency to attach themselves to the microscopic grooves found in most contact lenses, and any outside contaminants that would normally get cleared away also have a chance to attach to the contact lens as well. After an extended period of time, this accuDry-Eye Syndrome, or dry lensesmulates a film over the top of the lens, resulting in distorted, blurry, and cloudy vision. Other than that, Colored contact lenses contains a number of layers, when we wear the lenses overtime, it may causes discomfort as our eye is lacking of oxygen as well as having dryness due to protein builds up.

3. Bad Hygiene Habits When Taking Care of Lenses.
Another important thing. You should have know that proteins and oils were build up on the lenses. However, there's still some peoples not being caution when it comes to lens care. Some would had neglect on washing their lens daily and thought that the lenses would get dirty in that way. But it's SO WRONG. Over the times, the lens solution would be less fresh and yes, being less clean & hygienic as well.

Do's& Don'ts
• Rub, rinse and store your lenses in the recommended solution before and after each use (except single-use lenses, which should be discarded after each wear)
• Discard and replace with fresh solution each time lenses are stored
• Clean the lens case with solution, wipe with a clean tissue then air-dry face down after each use
• Discard solutions that are past their expiry date
• Use only the solutions specified by your eyecare practitioner
• Make sure you take all the solutions you need with you when travelling

Don't ....
• Use tap water, or any other water, on your lenses or lens case
• Wet your lenses with saliva
• Re-use or top up solution
• Decant solution into smaller containers
• Wear lenses left in the case for more than seven days without cleaning and storing them in fresh solution
• Switch the solution you use except on the advice of your eyecare practitioner
• Use any eye drops without advice from your eyecare practitioner

If you did follow the rules on how to take care of your lenses, you should be totally safe from any eye infections.

I hope that these would be helpful for some of you who just started to try out wearing lenses.

Till next time. :*
