Delivering On-The-Spot Customized Prescription

Eyeglasses for Children and Adults

Greetings!

​

My name is Nizar Mamdani. I was born in a small town in Tanzania, East Africa, and received my education in both Tanzania and Japan. Together with my wife, Dr. Marsha Mamdani (Ph.D.), we founded First Sight Eyeglasses, Inc., a 501(c)(3) organization dedicated to transforming global vision care by providing affordable and accessible eyeglasses in under ten minutes. To date, tens of thousands of First Sight's high-quality eyeglasses have been distributed across 31 countries.
We believe that your commitment to improving lives aligns seamlessly with our mission. By integrating First Sight eyeglasses into your programs, we can significantly enhance educational outcomes and overall quality of life for those affected by vision problems.
First Sight is a groundbreaking initiative aimed at addressing one of the most common yet overlooked challenges in developing regions: vision impairment among schoolchildren and adults. Our solution is uniquely designed to meet the needs of individuals in resource-limited areas.

Clinically tested by a major medical center, First Sight eyeglasses exemplify simplicity and efficiency. Here’s what makes them ideal for your programs:

​

  • Low Tech, High Impact: Our eyeglasses are designed for ease of use, requiring no electricity or sophisticated equipment.

  • Quick and Efficient: A non-professional can conduct visual screenings and fit customized eyeglasses on the spot in under 10 minutes.

  • Foolproof and Accessible: Creating customized prescription eyeglasses with First Sight is straightforward, ensuring that anyone, regardless of their technical expertise, can manage the process with ease.

  • Completely Mobile: Due to their portability, First Sight eyeglasses can be distributed anywhere, perfectly catering to the needs of remote or underserved communities.

  • Speed and Efficiency: Each pair of custom prescription eyeglasses can be prepared in under 10 minutes, providing immediate relief to those in need.

  • Cost-Effective: Our eyeglasses are not only affordable but also enhance accessibility, ensuring vision correction reaches a broader audience.​

Pre-Screening Set Up Process for
Myopia/Near Sight 
(for individuals being tested for distance glasses, -1.50, -2.00 lenses, etc.)

Pre-Screening Setup Process:

  1. Gather Equipment:

    • Ensure you have the necessary tools: lens trial sets (-1.50, -2.00, etc.), an eye chart, a lens tree, and an eye blocker.

    • Prepare medical-grade wipes for cleaning equipment.

  2. Create a Comfortable Environment:

    • Find a well-lit, quiet space for the screening.

    • Arrange seating for the recipient at a comfortable distance from the eye chart.

  3. Prepare the Eye Chart:

    • Position the eye chart at the appropriate height and distance (typically 20 feet or 6 meters) for accurate testing.

  4. Check Equipment:

    • Inspect the lens trial sets and ensure they are clean and free from damage.

    • Set up the lens tree for easy access during the screening.

  5. Sanitize Surfaces:

    • Wipe down any surfaces that will be used during the screening, including the lens tree and eye blocker.

​

Setup for Visual Screening with Tumbling E’s Eye Charts

​

  1. Select Location:

    • Choose a well-lit area with ample natural light for optimal visibility of the charts. Ensure the space is free from distractions.

  2. Position the Charts:

    • Place two identical Tumbling E’s Eye Charts on adjacent walls or solid surfaces at eye level. The charts should be spaced adequately apart to allow the individuals being tested to stand or sit comfortably.

  3. Check Alignment:

    • Ensure that both eye charts are aligned at the same height and distance from the seating area. This will help maintain consistency in testing conditions.

  4. Lighting:

    • Verify that both charts are well-lit. Adjust any lighting as necessary to eliminate shadows or glare, ensuring clear visibility of the letters.

  5. Test Area Preparation:

    • Arrange seating or standing space for the individuals being tested, allowing enough room for them to move between the charts if needed.

  6. Final Check:

    • Confirm that everything is securely positioned, and that the environment is conducive to effective visual screening.

​

Once set up, you’re ready to conduct the visual screenings using the Tumbling E’s Eye Charts

Pro-7-300x209.jpg
Pro-8-300x209.jpg

Using the provided tape measure, mark 20 feet (6 meters) from the wall. The charts should be in well-lit areas (including natural lighting).

Screening Process for Myopia/Near Sight

Instruct the person being tested to cover their left eye using the Eyesight Blocker included in the First Sight Kit. This will help ensure an accurate assessment of their vision in the right eye.

Image-5.jpg
Image-6-300x289.jpg

  1.  Ask the person being tested to read the Es on the Tumbling Eye Chart by indicating the direction each E is facing. They can use a flat hand gesture to show the direction.

  2. Start at the top of the chart and move downward, allowing the individual to read each line.

  3. Determine the point at which the person can no longer clearly identify the direction of the E.

  4. The last line they read correctly represents their uncorrected visual acuity (UCVA).

  5. Repeat the procedure for the right eye, following the same steps.

  6. If the individual can read all the way to the bottom of the eye chart, their eyesight is considered normal.

  7. If they cannot read to the bottom, move them to the next identical screening station, using a lens tree.

Screening Steps for Near Sight (Myopia) with the Lens Tree

  1. Prepare: The tester holds the First Sight lens tree (BLACK). The person being tested does not hold it.

  2. Occlude Left Eye: Cover the left eye with the Eyesight Blocker.

  3. Read Chart: Ask the person to read the Es on the eye chart, indicating direction with a hand gesture.

Eye-44-300x225.jpg

CAUTION: Children sometimes stare and focus on the chart, which may cause the chosen lens to be too strong. They should be told to relax and not to try too hard by concentrating. Closing their eyes for a few minutes. If they were focusing too much, the lens choice could be reduced by 0.50.

4. Identify Limit: Start at the top and move down until they can no longer read clearly.

5. Record UCVA: The last line read is their uncorrected visual acuity (UCVA) on the Data sheet provided.

Tips For New Recipients of FIRST SIGHT Eyeglasses

​

Caring For Your New Eyeglasses

​

  1. The glasses come in white First Sight fabric pouches: Place the glasses in the pouch when you are not using them to prevent getting them dirty or scratching the lenses,

  2. When the lenses get dirty (for example with fingerprints) you may wash them with soapy water and dry them with a clean cloth. Do not use abrasive materials (like your nails) to remove stains, the lenses can scratch easily.

  3. If you’ve been given glasses with strong corrections, like -4.0 or -5.0, or if you haven’t had glasses before, don’t be surprised if you get slight headaches or discomfort during the first couple of few days. Your brain needs to get used to your new vision to acclimate to them, wear your glasses a few hours at a time and take breaks to rest your brain if needed. This will most likely go away after 2-4 days.

  4. If you received “reading glasses” (with a + correction), you probably do not need to always wear them, just when you are reading,

  5. After a few weeks of using your glasses, if you feel that your vision is not perfect, please ask to be retested to assess if your correction needs to be adjusted,

  6. Your vision is likely to change over time. It doesn’t mean that the glasses aren’t working, just that you need new lenses; this can be done with repeating your visual screening and getting new lenses at your school or where you received your original first pair of eyeglasses. You’ll keep your frame. Ask to be retested every year, if possible,

  7. If one of the lenses ever falls from the frame, this can be fixed easily by carefully inserting it in the frame, or better yet, if possible, visit the place where you received the eyeglasses. They will be able to easily fix this.

  8. Guard your eyeglasses for any breakage or damage.

  9. Enjoy your new pair of First Sight eyeglasses.
