I suffer from year round allergies which always affect my eyes. The mornings are especially rough. I have found tremendous relief with these drops. What impresses me most is that they are effective in treating my eyes while being one of the gentlest eye drops on the market. Most eyedrops in this category have an initial stinging sensation, these are soothing the minute you put them in your eyes. The redness begings to disappear immediately and the rough scratchy feeling soon disappears as well. I have always been concerned about overuse of drops, but these gentle drops put me at ease. I am impressed with the price point of these drops as well. Its a fair size bottle and literally one or two drops will last for hours. During the spring and fall when my allergies are at their worst I do reapply these in the afternoon. I am then set for the rest of the day. For those with severe allergies I recommend trying these drops.
