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.
The short answer is yes. But you will be doing a lot of guessing and spending money on figuring out your strength, Base Curve, and Diameter. You are better off getting them measured.
You need to have a regular eye exam to determine the strength of your prescription. They will also need to measure the curve of your eye, to find contacts which will fit your eyes best.
Yes, wearing contacts that aren't yours can severely damage your eyes. Be sure to get contacts that are right for your eyes.
this is a confusing question. I am thinking it was how can you get new contacts without an eye exam and insurance. - your exam and contact lens prescription is only good for one year from the date of service. By law no eye place is to dispense you contacts without a current eye exam due to you put them in your eyes. There is vision insurance out there that will pick up the cost of the eye exam minus a copay. most medical insurances will also cover one routine exam per year or every other year. all you need to do is call the member services number on your card.
wear contacts
If you're new to wearing contacts your eyes may burn when you take the contacts out. Increased oxygen to your eye can create the burning or stinging sensation. As your wear contacts more regularly your eyes will adapt; if they do not become used to the contacts and your eyes still burn after a week or two, go and see your optometrist or ophthalmologist.
It all depends on the type of contacts and prescription of your eyes.
Actually I have kept my eyes open for about four minutes, but I had contacts in. With out contacts in I can only keep my eyes open for 45 seconds.
It is best to first consult to an optician or a local eye doctor before getting coloured contacts as they can cause adverse reactions with the eyes, but the best shade for brown eyes is green.
As long as they can put them in their eyes, anyone can wear contacts.
They are exactly the same as regular contacts. So no.
