  • hi welcome to engvid.com i'm adam in today's  video i'm going to walk you through the process of  

  • buying glasses okay whether prescription glasses  or regular glasses some people need to wear them  

  • you need to know how to go into a glass store  and buy yourself a good pair so before we do  

  • that we're going to look at who you should  talk to before you buy your glasses okay  

  • you can go to an optometrist an ophthalmologist  and a petition or any of these guys okay or women  

  • the first of all what's the difference  between optometrist and ophthalmologist  

  • an optometrist is sort of a doctor i mean i don't  want to offend anyone who's an optometrist but  

  • it's not a real medical doctor these people  go to university for a shorter amount of time  

  • and they study a very specific or very limited  amount about the eyes so they can do a vision  

  • test they can check your vision they can  prescribe glasses for you if you need them  

  • if you have certain diseases they can prescribe  medicine to correct it and drops and whatnot  

  • an ophthalmologist is an actual medical doctor  he or she went to full medical school and then  

  • specialized in the eyes okay in eye medicine this  person can also be a an eye surgeon and if you  

  • need any work especially if you have cataracts  things like that so if you have very serious eye  

  • issues you would go to an ophthalmologist if you  just need your vision tested and you need glasses  

  • you can go to an optometrist now an optician  is the person who makes glasses okay  

  • he or she gets a prescription from the optometrist  and creates your lenses and puts them on the frame  

  • etc some opticians some opticians also give vision  tests but it's highly recommended if you need  

  • glasses go see an optometrist and buy your glasses  from the optician don't get your vision test  

  • there necessarily so now what's going to happen  they're going to check your vision if you have  

  • 20/20 vision then your perfect vision right you  don't need glasses everything is fine basically  

  • what 2020 means this is not your prescription  number this means that anything that is 20 feet  

  • away you can see clearly with both eyes if you're  not 20/20 if you go below this then they start  

  • measuring your eye the curvature of your eye  okay the curve of your eye and then they know  

  • where the light is going and hitting your cornea  but we won't get into all the technical stuff  

  • and that'll give you a prescription now  some of you might be farsighted some of  

  • you might be nearsighted farsighted you can see  clearly far away nearsighted you can see clearly  

  • something that's up close now i'm not going  to get into all the details because ronnie  

  • another teacher here on engVid did a very good  lesson on that you can go check that lesson out  

  • i'm going to concentrate on the glasses what you  need to know to buy them so first of all if you're  

  • buying glasses keep in mind some people call them  spectacles this is a little bit old-fashioned but  

  • some people still use it and you should get  a prescription let me use the blue one here

  • basically make sure that the doctor gave you the  exact number that you need for each eye okay now  

  • when you're buying glasses you have  to think about the lens and the frame  

  • now if you're buying contact lenses that go right  into your eye you just go by the prescription you  

  • put them in your eye no problem there so when  you're buying lenses now there are different  

  • types of lenses you can buy a bifocal a bifocal  basically let's say this is the lens you have two  

  • lenses in one lens and at different focuses and  that's why it's called bi trifocal will have three  

  • for close for middle for distance okay or you  can buy progressives now i don't know exactly  

  • what progressives look like but the idea is that  they work for both far and near-sighted the lens  

  • your eye adjusts to the lens it's built in a way  that you can see in all directions right anywhere  

  • you look any distance it will work and your eyes  will adjust naturally and everything will be clear  

  • okay these are very good a little bit expensive  but if you have different types of visions you  

  • can get them all fixed in one shot you can  also buy transitions now what transitions do  

  • they adjust the tint okay so this is a tint this  is the darkness basically the lens becomes dark  

  • so when you go outside and it's sunny the the  lens becomes dark naturally when you go back  

  • inside the darkness goes away and they become  clear again so it's basically regular glasses  

  • and sunglasses in one lens there's a certain  chemical inside that adjusts to the light  

  • or you can just buy sunglasses now be very  careful when you're buying sunglasses okay  

  • make sure that they have uv protection there  are a lot of cheap sunglasses that you can  

  • buy on the street or in the store ten dollars  twenty dollars and they say uv protection but  

  • be very careful most of them don't  have it it's just cheap plastic  

  • it's dark now what happens if you don't have  uv protection the darkness opens up your pupil

  • yes same word as student but pupil is the black  area the iris basically the black area of your eye  

  • it opens up more and more uv comes in so if you're  buying cheap sunglasses you're actually hurting  

  • your eyes very much okay make sure you have  the uv protection when you're buying sunglasses  

  • transitions are excuse me automatically come  with it now tinted glasses they just put a coat  

  • basically a plastic coat of like a sunglass  coat not good be very careful with those now  

  • you can also get some features on your lenses  for example anti-glare anti-glare they're also  

  • called anti-reflective what this is is a special  coating on the lens that doesn't let the light  

  • sit on the lens so if you're wearing glasses  and you see little spots of light from let's say  

  • light bulbs or the sun or whatever this coating  makes them not there so everything is very clear  

  • another way you might see is polarized polarized  glasses especially sunglasses basically remove the  

  • glare so all you see is very clear what's in front  of you without the little light spots on the lens  

  • now next you have to think about your  frame this is more of a fashion choice  

  • but it also has to be a a  question of comfort right  

  • you can have frameless glasses or you can  have ribbed glasses so let's say this is the

  • sort of let's say this is the glasses this  is the frame now you can have only the lens  

  • or you can have a rim that's holding the lens  in like that right both are available it's a  

  • matter of choice more than anything else okay so  rimmed with the frame frameless no frame only lens  

  • then there are different styles aviator wayfarer  etc you don't need to worry about these names when  

  • you go to the store to buy your glasses they will  show you all the different styles you try them on  

  • see which one you like etc make sure  that they are sitting comfortably  

  • on the bridge of your nose so this is the  bridge of your nose it looks like a bridge  

  • make sure your glasses are sitting comfortably  most glasses these days are made of plastic  

  • the lens is made of plastic glass is too heavy  it sits on the bridge and for many people it  

  • gives them a headache because the weight  squeezes now frames come in metal in plastic  

  • or titanium titanium is very very lightweight  ultra lightweight we can say i'll put it here

  • ultra lightweight means super light you  don't even really feel them so those are very  

  • comfortable but again more expensive and then you  have your contact lenses again as you need so if  

  • you need glasses like for example i'm gettingbit older now i need reading glasses or i will  

  • soon enough i need to go and make sure  that i get the right glasses for me  

  • make sure you get the right glasses for you  you're gonna have to wear them every day  

  • make sure they're comfortable okay  if you have any questions about this
