If I tighten the goggles very tight its very uncomfortable if I don't tighten it very tight water comes in

This goggle is just what I imagine for the perfect swimming.

I recently joined an aquatic center and despertly needed perscription goggles that didnt break my budget. I came across these Tracer's Goggles and couldn't believe the price. I bought this pair and they're exactly what I wanted. They don't give you perfect 20 / 20 vision, but they're close enough to see everything clearly. They're reasonably comfortable, don't fog, functional, and can't beat the price. What's not to love.

These fit very snug against the eye socket, maybe too snug, but for anyone who fears water in his/her eyes, these are great.

I bought these for my 12 year old who does not yet wear contacts.  She hated that when she was swimming she couldn't see clearly.  These corrected her vision enough for her to see better, although not perfect since they aren't customized.

Good fit, no leaks, no fogging!  Only downside is that it doesn't come with a case or plastic box to store them in after use.
