Is contact lens exam the same thing as vision eye exam?
I believe the exam is the same, but with the contact lens exam the optometrist checks and measures your eyes for the proper fitting of contacts.
Where could one get a prescription for Acuvue lenses?
A prescription for contact lenses, including Acuvue, must be obtained from a licensed and registered optometrist or ophthalmologist. The optometrist or ophthalmologist can only write the prescription after performing an eye examination on the patient.
Yes, it can. There are many options to help correct it. e.g. eye surgery, contact lenses and glasses. Only wear contact lenses if you have no reaction. Glasses will change the shape of the eye, because it corrects the vision. The shape of the eye will change from a rugby ball shape, into a sphere. My advice, based on experience, is get a pair of weak glasses perscribed to you, by your optician, and wear them when you need them/ when carrying out focused activities eg. reading. If you wear stronger glasses all the time, your eyes will become weaker. Also, overtime, your eyeball will change and so will the shape, but the glasses will help speed up the process
If you are not using disposable contact lens, how long is a pair of contact lens good for?
When using a pair of hard contact lenses, frequent replacement lenses should be replaced monthly or quarterly. Traditional (reusable) lenses should last six months or longer. It is recommended that they be changed at least once every 8 or 9 months.
I have been wearing disposable contact lenses for years. I started out wearing the Durasoft 3 lenses that I replaced once per year. I currently wear Freshlook lenses and replace them every month. I think it is more healthy that way.
Who invented the soft contact lens?
Soft contact lenses were a big invention in the field of contact lenses. It dates back to 1959-60 when Otto Wichterle and Drahoslav Lim first developed soft lenses. These were much better than earlier versions of lenses which were very hard for the eyes. Being first lenses to allow oxygen permeability to the eyes, they soon become quite popular.
However, you would be surprised to know that a lot of names are linked with the invention of first contact lenses. There is no single name you can attribute the invention of contact lens. From 1500 to 2000 a lot of research and development has taken place in the field and several names are associated with the development of contact lenses. Some of the prominent names are:
Leonardo da Vinci(For conceptualostaion in 1508)
René Descartes(1636)
Thomas Young (1801)
Sir John Herschel(1845)
Adolf Eugen Fick (1887)
Louis J. Girard (1887)
William Feinbloom (1936, introduced plastic lenses)
Otto Wichterle and Drahoslav Lim (developed soft lenses in 1960s which got approved in 1970 by FDA).
What are the benefits of wearing contact lenses?
Glasses and contact lenses can make your vision clearer. However, they can be harmful to your eyesight in the long run.
In order to improve your eyesight, you should do eye exercises designed to permanently improve your vision. Such exercises only take about 10 minutes a day and can be very effective if done correctly.

Can i use my glass number to make contact lenses?
-This all depends on the glasses Rx. If you have no astigmatism (usually referred to as cyl) then it's possible. However, contacts come in different curvatures, so if you pick one that is not the right curve for your eyes, they will either be too tight not allowing oxygen or moisture to the eyes or too loose which will cause them to be uncomfortable and vision is usually not stable.
-Also, any minus power Rx above -4.00 or +4.00 needs to have a vertex correction since there is a difference in power of a lens when it's on the eye versus in front of the eye. So, it's not usually recommended.

How do you put contacts in your eyes for the first time?
Wearers of contact lenses share their views:
- I use the EyePOD Contact Lens Kit to easily insert and remove my contacts. I just take the adapter, put it on the EyePOD, place a drop of water on the center of the adapter, place the adapter on the contact (my fingers never touch it anymore, no more worrying about how clean they aren't) then open my eye wide, look into the center of the adapter, and bring it to my eye, a light press, then the contact is on my eye, perfectly 1 try every time, it's pretty much the same to take them out
- Wash your hands very well (personally, I like to wash with lukewarm water, because it cleans better than hot) and dry them properly. After that, take the hand you feel most comfortable with and grab your contact. With you free hand, take your index finger and pull towards the sky and your thumb and pull towards the ground. Then, look down (it may seem like you're poking yourself in the eye and you could mess up) and apply the contact to your eye. Next, take the contact finger and pull your bottom lid down and make sure that the contact matches your eye or until the contact sticks to your eye. Once you have it in your eye correctly, blink (but not too hard). If it feels weird, close your eye and rub the top part, because you may have an air bubble.
- Your optometrist or contact lens fitter is obliged to demonstrate to you how to insert and remove lenses correctly. There are several different methods; you need to find one that will work for you. I strongly suggest that you do not follow the advice given below - if you insert or remove your lenses incorrectly, it can be very harmful to your eyes. And never take advice on solutions from anyone other than a qualified optometrist. I've seen some nasty cases of permanently damaged eyes caused by improper use of contact lenses and solutions. Your sight is precious - don't mess around with it!
- Add two drops of Renu solution (doctors recommend sterile saline solution) and put the lens in the eye. Since there is liquid, it will stick fast. Rotate your eyes with the eyelids completely open. That's it.
It's important that you go to an optometrist and get them to show you how to look after your lenses and also how to put them in.
- Pull down the lower lid of your eye with your right hand and hold the top up with your left hand. Then, using the index finger of your right hand, put the contact in your eye. Wait for a second, then slowly remove your hand. The contact should stay in place on your eye.
- I put the left hand over the top lid and pull it up. I hold the bottom lid down and place the wet contact on my middle finger. I hold my head straight and roll my eyes to look down. I touch the lens on my eye making sure my lashes don't touch the lens. The key is looking down with my eyeball.
- Put an eye drop in each eye directly before placing the lens in. This will help lubricate and seal the contact to the front of the eye. I find that looking SLIGHTLY upwards helps me, but it may vary for you. Do not move your eyes until you have blinked a few times, and the contact should pretty well seat itself.
If you are still experiencing difficulty, take your contacts into any glasses store, or your eye doctor, and they will show you. Bring your own solution.
- First, practice touching the white of your eye, but not with your fingernails! You need to do this, or you will immediately blink when you try to put the contact in your eye for the first time. I usually look towards my other eye and then touch the eye towards the outside. You really need to get comfortable doing this before you will be able to put a contact in.
When I'm ready to try putting it in my eye, I also look towards my other eye and put it in towards the outside. Don't put it in over your iris. I usually put a drop or two of saline in the lens before I put it in my eye. After a couple of blinks, it will find its way over your iris.
- The first time you try it, you will get EXTREMELY frustrated and want to give up. The same thing goes for trying to get them out. It felt like I'd never get them in the first time.
Can your lenses be cut to fit smaller frames?
your lenses can be cut to fit to smaller frames but the pupil distance of the lens will be changed. if your eyes are sensitive to change in pupil distance, you will experience dizziness and headache after you cut to fit your lenses. therefore, it is more advisable to get new lenses.

The diameter of the lens prescribed is specific to the shape of your eye. If you use contacts of the incorrect size, irritation and/or blurriness may occur, and they may be prone to falling out of your eye during normal use.
Use the measurements prescribed by your optometrist. It's the reason prescriptions are required to buy them.
