How to Make Eclipse Glasses at Home: DIY Guide

Find out how to make Eclipse Glasses. Watching a solar eclipse is an awe-inspiring and remarkable experience that unveils the wonders of the universe. 

However, it is crucial to prioritize the safety of your eyesight by using appropriate eye protection. 

While commercially crafted eclipse glasses stand as the optimal and most secure choice for safeguarding your vision, it is reassuring to know that you can fashion your own pair at home if the need arises. 

How to make eclipse glasses:

1. Understanding Eclipse Glasses

Eclipse glasses are designed to filter out harmful solar radiation, including ultraviolet (UV), visible, and infrared light, allowing you to safely view a solar eclipse. 

The glasses use special-purpose solar filters to ensure you don’t damage your eyes. When making your own eclipse glasses, it’s crucial to use materials that meet the ISO 12312-2 international safety standard for direct solar viewing.

2. Materials Needed

To create your eclipse glasses, you will need the following materials:

• Black Polymer Film or Mylar Film: These materials are specifically designed to block out harmful light. They can be found online or at some specialty stores.
• Cardstock or Heavy Paper: To create the frame for the glasses.
• Scissors: For cutting the paper and film.
• Glue or Tape: To assemble the glasses.
• Ruler: To measure and cut accurately.
• Template: You can create or print a template for the glasses.

3. Creating the Template

Start by creating a template for your eclipse glasses. You can find printable templates online or make your own. The template should include the following parts:

1. Frame Outline: The outer shape of the glasses, including the arms and the part that fits over your nose.
2. Lens Cutouts: Two circles where the solar filter film will be attached.

Print or draw the template on a sheet of cardstock or heavy paper. Make sure the lens cutouts are large enough to cover your eyes completely.

4. Cutting the Template

1. Cut Out the Frame: Using scissors, carefully cut out the frame shape along the outer lines. Make sure to also cut out the areas for the lenses.
2. Cut Out the Lens Areas: The lens cutouts should be precise to ensure that the solar filters fit perfectly.

5. Preparing the Solar Filters

1. Cut the Solar Filter Film: Using scissors, cut the black polymer or Mylar film into two circles that are slightly larger than the lens cutouts in your template.
2. Attach the Filters: Carefully glue or tape the solar filter film over the lens cutouts. Ensure that the entire lens area is covered, with no gaps or overlaps.

6. Assembling the Glasses

1. Assemble the Frame: Fold and glue or tape the frame parts together. Ensure that the glasses will fit comfortably on your face. You may need to adjust the size or shape to fit your face correctly.
2. Secure the Filters: Make sure the solar filters are securely attached and that there are no loose edges. The filters should be positioned directly over the lens cutouts without any gaps.

7. Testing the Glasses

Before using your homemade eclipse glasses, it’s essential to test them to ensure they provide adequate protection:

1. Check for Gaps: Look through the glasses at a bright light source. The entire field of view should be uniformly dark, with no visible light leakage.
2. Inspect the Filters: Ensure that the solar filters are intact and not damaged. They should not have any scratches or holes.

8. Using Your Eclipse Glasses Safely

When using your eclipse glasses, follow these safety tips:

1. Never Look Directly at the Sun Without Proper Protection: Even during an eclipse, looking directly at the sun without proper protection can cause severe eye damage.
2. Supervise Children: If children are using homemade eclipse glasses, ensure they are supervised to avoid any accidents or misuse.
3. Avoid Using Damaged Glasses: If your glasses become scratched or damaged, do not use them. They will not provide adequate protection.

Making your own eclipse glasses at home is a satisfying endeavor that allows you to safely witness one of nature’s most spectacular occurrences. 

By following these methods and utilizing the proper materials, you may create a set of eclipse glasses that will protect your eyes while also improving your viewing experience. 

Always emphasize safety and make sure your glasses fulfill the required standards for solar viewing. Enjoy the eclipse knowing that your eyes are fully protected!
