Frequently Asked Questions (FAQ)

• Can I put my prescription in the EN4300 frames? Yes. The included demo lenses must be replaced by an optician or online optical lab with your custom prescription lenses—single-vision, bifocal, or progressive.
• Are the EN4300 glasses heavy or uncomfortable? No. The plastic construction combined with a slim-profile full rim design keeps the total weight low, making them suitable for 12 or more hours of continuous wear.
• What age range are the EN4300 frames designed for? These frames are sized specifically for children's faces. We recommend comparing the listed measurements (lens width, bridge, temple length) against your child's current frames for the best fit.
