Pink Contact Lenses Gain Popularity

Pink Contacts

Pink Contact Lenses Gain Popularity

Pink contact lenses have been gaining popularity over the last few years until now reaching a point where both men and women, young and old are wearing pink contacts.


Colored contact lenses have been something that everyone has wanted since they were first introduced. Of course then colored contacts only came in very basic colors. 

Nowadays not only can you find you standard colors such as blue and green but contact lenses in colors such as violet and pink as well as all kinds of crazy contact lenses that are for role playing and Halloween.

Pink Contacts are Popular

Lately it seems that pink contacts are becoming more and more popular, you can find all kinds of videos on YouTube of both men and women wearing pink contact lenses. Of course for the ladies it is more understandable that they would gravitate towards pink lenses, after all what makes a woman feel more girly than pink.

On the other hand I don’t really understand .what is up with men wanting to wear pink contacts, however I am not one to judge and believe you should wear whatever makes you feel good so men, break out those pink contact lenses.

Pink contacts are not the only color of contact lens to be “in” this summer. Women especially love to make fashion statements and this year colors like violet and purple seem to be in. Again these colors, I believe, are colors that make a women feel soft and girly so again it makes sense that they would be popular colors.

Men on the other hand tend to go in the opposite direction and turn to the craziest and strangest contact lenses they can find which often times takes on the form of some sort of “monster” eyes. It will be interesting to see what trend rises above the rest come this next Halloween.

Some do so because it is a requirement for their movie or play while others do so because they think it looks very cool.

Do you want a blue eye color? Well, now you can easily have them. Beautiful eyes can now be yours. blue, green, gray, violet or even red and the best thing is you can do it within seconds.

But, a lot of people are hesitant to use colored contact lenses, they think it is not safe. The horror stories about wearing colored contact lenses are what is preventing a lot of people from wearing them. Can these lenses really affect out health?

There is nothing to fear about colored contact lenses. You will not even feel like you are wearing anything. Remember to go to your physician first before you buy any colored contact lenses. Your doctor can recommend a brand which will be suitable for you. Do not be cheap when it comes to buying colored contact lenses. Do not buy brands which are not recommended by physicians.

Wear your colored contacts properly and you should not have to worry about anything. Eye infection and other problems can be easily avoided if you follow what your doctor says about wearing contacts.

Here are some safety tips which you should keep in mind if you plan to wear contacts.

Never buy colored contact lenses from flea markets or salons. Lenses sold from other than licensed sellers may not be safe. The FDA has advised people to only purchase from licensed retailers.

Visit your doctor for a prescription. People who have eye problems just cannot wear any type of contact lens. It is even a must to consult the doctor first even if you do not have any problems with your eyes.

Never swap contact lenses with other people. You can have serious eye problems if you do this. Contact lenses are not to be used by more than a single person.

Clean your contact lenses regularly. Never ever go to bed wearing your contact lenses, this is a cardinal rule which should never be forgotten. Remember to always remove your contacts before you go to sleep.

Clean contacts mean healthy eyes. It is important that your contacts are clean because if there are any organisms there, they can get to your eyes. Use the cleaning liquid and not tap water to clean your colored contact lenses. Do not handle lenses when your hands are dirty. Do not leave your lenses lying around the house.

If your lens have been ripped, refrain from wearing them, you have to get a new one. Go to your doctor at once if something is wrong with your eyes.
