I am strong protan
I am strong protan. These glasses are amazing like near a miracle. I own 2 pairs of the Ellis style. I've had them for 6 or 7 years. I wear them all the time outdoors. They work best outdoors in sunlight, in natural light. The correction diminishes in proportion to the strength of the light. Inside, if the natural light is bright enough they will work. Otherwise artificial light doesn't help much. No more brown and gray world. Reds are not just dark neutrals. My world is so much more colorful. Colors in the orange-red, red, red-violet, violet spectrum are just brilliant and vibrant, like sunsets, stop signs, flowers, even the clothes people wear. In greens the correction is moderate but worthwhile. They work so well I am able to paint, do artwork, speak about colors with a degree of confidence. The correction has a lingering effect where the correction is somewhat moderate in some reds when I am not wearing them. Plus the Ellis style looks good on me. If colors matter, these glasses are near life changing and I recommend them. Hope the review helps.
