Eye diseases that can cause constricted visual fields (“tunnel vision”) include glaucoma and retinitis pigmentosa (RP). In the early stages of these diseases, the visual acuity is often not affected, only the visual field (Item # 104). Advanced disease may lead to a further constriction of the visual field and a loss of visual acuity (#103).
“I recently received a pair of your goggles simulating 10 degrees of tunnel vision. I am very pleased with these goggles and have had the opportunity to let several people try them, so they can understand a little better how I see the world. I won’t tell you the grown up’s verbal response, but my teenage daughters tried them and after about three minutes said, “This isn’t fun.” Then they told me they understood a little better how I felt.” ( more )~ Roger Buchanan
Did you know…?
- Glaucoma is the second leading cause of blindness in the US and is the leading cause of blindness among African-Americans.
- Glaucoma has no warning signs. Left untreated, glaucoma can lead to permanent vision loss or blindness.
- RP is characterized by progressive visual field loss and night blindness. Its occurrence is reported to be between 1 in 2,000 and 1 in 7,000 and is more common in males.
- In the US, one definition of “legal blindness” is a visual field no greater than 20°. Item #104 portrays this maximum level of visual field allowed in determining this status.
