Intro: How to Improve Eyesight
This instructable will show you how to improve your eyesight in two ways.
The first is to eat more carrots (with some fat like in yogurt or something else) or to drink more carrot juice. The vitamin A in the carrots (splitted by the fat molecules) will help you to overcome your night blindness and bad eyesight that are results of the lack of the vitamin.
The second is to build a pinhole spectacle. To be honest: The effects of pinhole spectacles are controversial. But if you want to relax and train your ocular muscle - the pinhole spectacles would be useful for you.
About the pinhole spectacles you can read here or in Googles own way to speak English and to translate. I would write some informations down right here, but there are many anatomical information which would be too hard for me (and my bad English) to explain. The pinhole glasses are not such a medical wonder, they were presented as, but maybe you can relax your eyes, wearing them for ten to fifteen minutes. At least it is an interesting experiment.
Please be sure to wear your pinhole spectacles only for training and not while doing dangerous things like driving a car, where you can hurt yourself or others. The pinhole spectacles concentrate your eyes attention on the seeing action and not the seen information.
You can make the glasses with different patterns:
1. normal pattern:
For the normal use and for everyone.
2. squared pattern:
For people, who don't wear glasses yet or people with under 2 diopters.
3. bi-focal patter:
Small holes with little distance between them in the upper half. Bigger and coarse holes in the down side. For the prophylaxis of elder people and above 3 diopters.
The unapproved patterns are easy to make, but in this instructable it is just the normal.
Step 1: Supllies.
- some old glasses
- paper* the attached or your own pattern
Step 2: Prepare Glasses and Print the Pattern.
First of all download the pattern and print it at 50% or in the ratio you think it fits for you.
While the pattern is printed, remove the glasses of your glasses. If the lenses are made of glass be very careful. If they are made of plastic like mine just push it out of the frame.
Step 3: Make Your Pattern "lenses"
Lay the popped out lenses onto the backside of the printed pattern. Draw the outerline of the lenses onto the paper, taking care that the outline you are drawing is within the pattern on the paper.
Then cut out two lenses along the outline you just have drawn.
After you have done this you can put the holes in with a needle as it is shown in the next step or you can glue the paper lenses onto the frame.
Step 4: Loop the Lenses.
Put something like cardboard or Styrofoam or just a mattress.
Loop the white points with a needle (you can use a small needle first and widen the holes with a bigger later).
Step 5: Use It.
The glasses are finished, now. You can use it.
The effect it is shown on the pictures. Read the intro again and the texts linked in the intro. Maybe do this whilst wearing the glasses.
