How To Choose Contact Lenses?

Comparison of contact lens wearing time and water

In addition to different brands of contact lenses, there are also different types of lenses with different wearing times. The main types are daily disposable and annual disposable contact lenses. By 2021, most customers in the market will choose daily disposable lenses because of the benefits and advantages compared to annual disposable lenses. Let’s analyze the different categories such as cleanliness, breathability, and convenience, as different contact lens wearers have different needs, and see which contact lens is most suitable for you.

Cleanliness and hygiene: Daily disposable lenses are freshly opened each time you use them, so there is no accumulation of eye dirt or dust on the lenses or left behind when cleaning Con.

Breathability: Monthly and annual lenses will become less breathable as you use them for longer periods, but since monthly lenses can be made of highly breathable silicone hydrogel material, they are more breathable, but you need to do an excellent job of cleaning them every step of the way.

Convenience: Daily disposable is the best, no need to clean, no need to remember the replacement time, just open and use daily.

Comfort: Daily disposable lenses are the thinnest and softest in design, with the lowest foreign body sensation, while annual disposable lenses need special treatment to cope with a year of use, so the lenses are thicker and have more foreign body sensation.

Combination of prescriptions: Annual disposable lenses can be ordered in different prescriptions, no matter whether 100-degree astigmatism, 200-degree astigmatism, 1500-degree astigmatism, or special curvature needs, almost any prescription can be ordered, which is much better than daily disposable lenses.

Price: The cost of annual disposable lenses is the cheapest for daily use, and 1-day contact lenses are more expensive, but one thing to keep in mind is the cost of the number of times you use contact lenses each week.

In addition to the above considerations, we also need to pay attention to the water content of the lenses.

How to differentiate between high and low-water-content contact lenses

Each contact lens has a different water content, ranging from 38% to 69%.

The low water content is 38% and the medium water is 42%-69%.

Medium water content is generally 42%-60%, and

The high water content is more than 60%.

When comparing contact lens water content, the higher the water content, the better. Water helps to introduce oxygen into the air for the lens, and the higher the water content, the more moister it is. The higher the water content, the better the oxygen permeability and the softer the lens. These can be considered as one of the selection factors.

High water content lenses will evaporate faster and the lenses will absorb tears to keep them hydrated, so if you wear them with dry eyes, you will dry your eyes faster and easier. Low or medium water lenses are more suitable for people who are prone to dry eyes and wear them for a long time every day.


How to choose the correct contact lenses hydration?

If your contact lenses feel dry. You can find out the water content of the lens and try some lenses with lower water content. If the situation does not improve after switching, try switching to lenses with a shorter wearing time, such as changing from monthly lenses to daily lenses.

Low water content lenses

Some of you may ask: I am already using soft water lenses and all still have dry eye problems, how should I choose? Freshlady suggests you choose silicone hydrogel lenses with a new material design.
