hello there welcome to the clinic so today I'm going to be checking some coloured overlays
over some near prints to see if it provides any relief from your visual stress. a few colours to
contrast and compare. you're going to select the overlay that feels most comfortable. I'll
be taking some notes as we go along, asking some questions and recording the results.
so the first overlay I want to compare
we have violet here
and I'm to run that against orange there
okay so the block of text that you're going to be focusing on is the block above the
blue reading line there. just to keep things where they should be it's the N14 size
print there, give yourself a few moments, have a read of N4,
tell me which overlay feels the most comfortable as you read along
Okay
you don't find that tint a little bit too intense there?
okay is the orange overlay helping much at all?
okay just comparing the two then which one feels most comfortable?
okay I'll leave the violet overlay in place
let's compare the violet again
the blue one there. and tell me what you think
okay so there's not a lot of difference there both are comfortable
okay so if you had to pick the most comfortable which one would
you say? okay we'll stick with blue, let's remove the violet. next up let's introduce
yellow there, have a read of N14 on each side
okay so immediately the yellow one makes things worse, right okay
so definitely no yellow, let me remove that one for you
now ley's introduce
the pink there. so we're going to compare pink against blue, have a read of the N14 print please
and when you've read just give me your opinions on each one
okay what score are you going to give the pink?
okay so the pink edges it, excellent, remove the blue
and let's introduce now
the lime green, comparing pink against lime green, N4 please
okay
tell me more
okay so very close, both are comfortable
any strain at all through the lime green
it's going to be a tough decision but which one would you say feels the most comfortable?
lime green, excellent remove the pink one there
okay I'm going to introduce a a teal colour now
just there, okay comparing a teal against lime green, take your time,
have read and give me your thoughts please
good
okay anything else you want to add?
let me remove teal. so far lime green
That's going to be
compared against a normal green. lime green, normal green.have a look at N14 again please
and give me your thoughts
good
which one appears to give you the least strain?
okay so no strain with either, good. of Which one brings out the contrast better of the black print?
okay looks like lime green is up there
lime green scores the highest. also notice that the normal green there was quite good and probably
pink in third there excellent. so this is the overlay that you could try to assist with your
reading. As I say you have the reading tracking line there to keep your eyes on the row of text
we'll do another check with those overlays next time because sometimes we can find a change
in what your visual system prefers
excellent now let's introduce
some more overlays. there bars are a little bit
thinner ,thinner strip there so it's going to help with your tracking a little bit better
but obviously more movement is required of the overlay. let's have a look let's find
two strips of text on the N14 there, 'so your contact lens is is only possible if the
Shamir as worn technology.' okay N14 size, take your time,
have a read of the print, let me know which feels the most comfortable to read
so it's blue and pink here. blue and pink
like I said the blue is a little bit difficult in terms of contrast that's
understandable. Dark print, fairly dark colour there, you're finding that the pink
is the slightly better one. what level of strain would you say you're experiencing with the pink?
Any strain at all with the blue?
Okay
let's remove this one
let's see what we have next. it looks like we have a yellow
there we go have a read, compare, give me your thoughts
okay so you find the yellow is a little bit too intense. does the yellow actually
make things worse than say looking at the print underneath or is the yellow definitely better?
Right, okay, I'll get rid of the yellow straight away and
introduce the next overlay for you. Looks at though we have orange,
just there orange against pink
What do you feel?
Okay
which is the best contrast in your opinion for reading,
which is easier to read based on the boldness? Pink, okay
all right which one gives you the most strain?
okay I'm going to move to a print below.
Just there
okay looking at the print which one would you say you could read quicker if you had to speed read?
orange excellent, let's remove the pink
Next up I think we have green
okay I'm going to stick with the new rows of text there.
how does the green make you feel when reading?
so it's comfortable but not easy to read, okay because it's a dark green there that's fine
so you're going to stick with the orange again, does that still feel comfortable for you to read?
okay I believe we have two more to go, let's have a look
over here we have grey
lovely grey colour there again orange. have a little look see what you think
okay so both very good, excellent
which is the easiest to read?
okay any strain at all with the grey?
okay let's remove this one there, it looks like grey's taken the lead
and if the final one I want to introduce red
okay okay just looking for me please
we have red and grey
excellent
there's a red is quite easy to read you can read that fluently, excellent
the grey is still holding up as well, brilliant
which one would you say is the must comfortable overall?
excellent so it looks as our grey
and orange have performed the best there
right so that's it for today. I'm going to get you back into the clinic next time. I may do a
rate of reading test and maybe some colourimetry, but I recommend the grey
and the lime green overlays today. all right thank you for coming in I'll see you next time
