Welding Helmets

My $70 one is good but the only problem i have is seeing what Im welding sometimes. If there is very little ambient light I struggle to see. Now I dont know if thats the Helmet, my eyesight or adjustment. Sometimes I just run a chalk mark down the join so I can see where im going. I wondered if a more expensive helmet would help. By the way I am NO tradesman welder just a hack.
