Prof. William Dalton, Ph.D.Blue light-filtering glasses provide many benefits, but users should be aware of their possible disadvantages. Some users experienced slight color distortion because of tinted lenses while performing daytime activities. Users have reported having slight adjustment problems when first using the glasses. Choosing the right ones eliminates this problem for most of us.
Visual Distortion Issues
- Tinted lenses alter color perception for design work
- Amber lenses shift yellows and greens noticeably
- Solution: Use clear lenses for color-sensitive tasks
Comfort and Fit Problems
- Poorly fitted frames cause pressure behind ears
- Loose temples allow light leakage reducing effectiveness
- Solution: Try multiple sizes before purchasing
Maintenance Difficulties
- Scratched coatings reduce blue light blocking
- Improper cleaning damages anti-reflective layers
- Solution: Use microfiber cloths and lens solution
The adjustment period occurs in only about 30 percent of new users. There may be a slight feeling of disorientation for the first three days. This condition is usually temporary and will resolve as your visual system adjusts to the new lenses. You should start wearing the lenses for short periods of one hour, with a gradual increase in the wear time.

Be sure to check the lens specifications before making a purchase. More affordable plastics may not offer either clarity or adequate protection.
