Soft contacts are types of contact lenses commonly prescribed for people new to wearing contacts. It is made with flexible plastic that allows oxygen to pass through to the cornea. It is also the first set of contact lenses to be manufactured in the 70s. Soft lenses have the following characteristics;
- Soft lenses are made from just two components; plastic and water. Some newer designs include silicone for more flexibility. Hence they are less irritable for first-time wearers.
- Very thin, soft contact lenses stick and conform to unique eye shapes. This feature also means that it is rather easy to forget you were wearing contacts if you have soft contact lenses on.
Hard contact lenses unlike the softer types are made from rigid gas-permeable materials. Also called rigid gas permeable contacts or RGP lenses, eye doctors approve these types of eye infections or defects that need to be corrected. RGP contact lenses are made of harder plastic that keeps their shape instead of conforming to the shape of your eye. They are better for people who are already comfortable with contacts and need to correct one eye problem or the other.
Gas permeable contacts have the following characteristics;
- They have a harder membrane and so do not change shape to fit eye shapes
- The rigid gas-permeable membrane allows for more oxygen to pass through. Hence is usually recommended for improved eye health and to correct myopia, most astigmatism problems, and any age-related vision loss.
Hard contact lenses vs. soft contact lenses
Now that you understand rigid gas permeable and soft contact lenses, it is time to compare them. From the definition, you can draw out the following ideas;
The thickness of the membrane:
Without too much going into detail, the rigid gas-permeable contacts have a thicker membrane than soft lenses. The thickness of the membrane directly depends on how they feel and conform to your eye. While RGP lenses might not conform to the cornea, they keep their form, providing sharper vision. Soft contacts are flexible and conform more easily. However, its ability to change its form to fit your cornea gives it a more blurred vision.
Level of Permability:
The level of oxygen that gets into your eye has a lot to do with eye health. The more oxygen is allowed, the healthier your eye will be under the lenses. Rigid gas-permeable lenses allow more air to pass through, which is why it is the most recommended contact for eye-related illnesses and defects. Some of them include farsightedness, nearsightedness, astigmatism, and so on.
How long will my contact lenses last? That question, as simple as it is, has a rather non-straightforward answer. If you are using soft contact lenses, you can only have them for about a month. The contact lens might have lost form after two weeks or less if you used them daily. But you can own hard contact lenses for two years without needing to have them replaced frequently. You’ll only need daily cleaning and annual checking with your eye doctor to ensure that the contact lens stays durable.
When it comes to comfort, soft contact lenses take the lead. They are lighter on the eye and fit very well on the cornea. They stick, so they don’t move around too often. However, this means that they are not the easier to remove. Hard lenses, however, are loose on the eye and uncomfortable. But they are easier to remove.
